128 byte receive buffer and 256 byte transmit buffer utilising buffer smoothing technology to allow for high data throughput.
MAX3232 RS-232 Line Driver
The MAX3232 device consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection pin to pin (serial-port connection pins, including GND). The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector. The devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/µs driver output slew rate.
P6KE150CA TVS Diode
The P6KE Series diodes is designed specifically to save your circuit from this sudden spike in voltage. P6KE Series diode are a very good Transient Voltage Suppressor (TVS) Diode. P6KE TVS Diodes are rated at 600 Watts and protects the sensitive electronic devices from the voltage spikes induced on circuit.
The characteristic of a P6KE TVS diode is that it respond to over voltages faster than other common overvoltage protection components such as varistors or gas discharge tubes. This makes TVS diodes useful for protection against very fast and often damaging voltage spikes.
AM26C32 Differential Line Receiver (SOIC)
AM26C32 is an improved replacement for AM26LS32 IC. The AM26C32 device is a quadruple differential line receiver for balanced or unbalanced digital data transmission. The enable function is common to all four receivers and offers a choice of active-high or active-low input. The 3-state outputs permit connection directly to a busorganized system. Fail-safe design specifies that if the inputs are open, the outputs always are high. The AM26C32 devices are manufactured using a BiCMOS process, which is a combination of bipolar and CMOS transistors.
AM26C31 Differential Line Receiver (SOIC)
The AM26C31 is an improved replacement for AM26LS31 IC. The AM26C31 device is a quadruple differential line receiver for balanced or unbalanced digital data transmission. The enable function is common to all four receivers and offers a choice of active-high or active-low input. The 3-state outputs permit connection directly to a busorganized system. Fail-safe design specifies that if the inputs are open, the outputs always are high. The AM26C31 devices are manufactured using a BiCMOS process, which is a combination of bipolar and CMOS transistors
MAX232 TTL to RS232 IC
MAX232 is a communication IC. It is used to convert TTL Signals to RS232 Signal and vice versa. MAX232 provides RS-232 voltage level outputs (approx. ± 7.5 V) from a single 5 V supply via on-chip charge pumps and external capacitors. This makes it useful for implementing RS-232 in devices that otherwise do not need any voltages outside the 0 V to 5 V range, as power supply design does not need to be made more complicated just for driving the RS-232 in this case.
The receivers reduce RS-232 inputs (which may be as high as ± 25 V), to standard 5 V TTL levels. These receivers have a typical threshold of 1.3 V, and a typical hysteresis of 0.5 V.
ISO3082 Isolated RS485 Transceivers
ISO3082 is an isolated half duplex differential line transceivers for TIA/EIA 485/422 applications. These devices are ideal for long transmission lines because the ground loop is broken to allow for a much larger common-mode voltage range. The symmetrical isolation barrier of the device is tested to provide 2500 VRMS of isolation for 60 s per UL 1577 between the bus-line transceiver and the logic-level interface.
Any cabled I/O can be subjected to electrical noise transients from various sources. These noise transients can cause damage to the transceiver and/or nearby sensitive circuitry if they are of sufficient magnitude and duration. These isolated devices can significantly increase protection and reduce the risk of damage to expensive control circuits.
The MAX481, MAX483, MAX485, MAX487–MAX491, and MAX1487 are low-power transceivers for RS-485 and RS-422 communication. Each part contains one driver and one receiver. The MAX483, MAX487, MAX488, and MAX489 feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps.
The driver slew rates of the MAX481, MAX485, MAX490, MAX491, and MAX1487 are not limited, allowing them to transmit up to 2.5Mbps. These transceivers draw between 120µA and 500µA of supply current when unloaded or fully loaded with disabled drivers. Additionally, the MAX481, MAX483, and MAX487 have a low-current shutdown mode in which they consume only 0.1µA. All parts operate from a single 5V supply. Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.
