MT8870 DTMF RECEIVER
The MT8870D/MT8870D-1 is a complete DTMF receiver integrating both the band split filter and digital decoder functions. The filter section uses switched capacitor techniques for high and low group filters; the decoder uses digital counting techniques to detect and decode all 16 DTMF tone pairs into a 4-bit code. External component count is minimized by on chip provision of a differential input amplifier, clock oscillator and latched three-state bus interface.
In addition, it is compatible with RS-422. The driver and receiver outputs feature TRI-STATE capability, for the driver outputs over the entire common mode range of 12V to −7V. Bus contention or fault situations that cause excessive power dissipation within the device are handled by a thermal shutdown circuit, which forces the driver outputs into the high impedance state. DC specifications are guaranteed over the 0 to 70˚C temperature and 4.75V to 5.25V supply voltage range.
LM2596S 5 Volts fixed Voltage Converter (TO-263)
The LM2596 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1 Ampere load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, and an adjustable output version.
Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed frequency oscillator.
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.

FT232 USB UART IC
Features of FT232
Single chip USB to asynchronous serial data transfer interface.
Entire USB protocol handled on the chip. No USB specific firmware programming required.
Fully integrated 1024 bit EEPROM storing device descriptors and CBUS I/O configuration.
Fully integrated USB termination resistors.
Fully integrated clock generation with no external crystal required plus optional clock output selection enabling a glue-less interface to external MCU or FPGA.
Data transfer rates from 300 baud to 3 Mbaud (RS422, RS485, RS232) at TTL levels.
128 byte receive buffer and 256 byte transmit buffer utilising buffer smoothing technology to allow for high data throughput.
MAX485ESA RS422 RS485 Interface IC
MAX485 is a low power transceivers for RS485 and RS422 communication. MAX485 contains one driver and one receiver. The driver slew rates of the MAX485 are not limited, allowing it to transmit up to 2.5Mbps.
These transceivers draw between 120µA and 500µA of supply current when unloaded or fully loaded with disabled drivers. MAX485ESA RS422 RS485 IC operates 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.
