DS1232 MicroMonitor Chip
₹40.00
DS1232 Micro Monitor? Chip monitors three vital conditions for a microprocessor: power supply, software execution, and external override. First, a precision temperature-compensated reference and comparator circuit monitors the status of VCC. When an out-of-tolerance condition occurs, an internal power fail signal is generated which forces reset to the active state. When VCC returns to an in-tolerance condition, the reset signals are kept in the active state for a minimum of 250 ms to allow the power supply and processor to stabilize.
The second function the DS1232 performs is push button reset control. The DS1232 debounces the push button input and guarantees an active reset pulse width of 250 ms minimum. The third function is a watchdog timer. The DS1232 has an internal timer that forces the reset signals to the active state if the strobe input is not driven low prior to timeout. The watchdog timer function can be set to operate on timeout settings of approximately 150 ms, 600 ms, and 1.2 seconds.

74LS83 4-Bit Binary Full Adder IC
IC 7483 4-Bit Binary Adder IC
74LS83 designed as a high-speed 4-bit fuller Adder IC featuring carry out function. The IC has four independent stages of full adder circuits during a single package. It?s commonly utilized in applications where arithmetic operations are involved. Although today we?ve cheap microcontrollers that would perform all arithmetic operations required for our application, in period of time the ICs like Adder, Counter, flip-flops etc were used for same. In this manner the complexity and therefore the BOM cost of the circuit design will greatly go low. 74LS83 may be a Full Adder with Carry in and perform feature. It?s a four-stage 4-bit counter, meaning it?s four individual Full adder circuits each of 4-bit inside one package. It also can be easily cascaded if quite four stages are required. These full adders perform the addition of two 4-bit binary numbers. The sum (?) outputs provided for every bit and therefore the resultant carry (C4) obtained from the fourth bit. These adders feature full internal look ahead across all four bits. This gives the system designer a partial lookahead performance at the economy and a lower package count when using ripple-carry. Because the adder logic, including the carry, is implemented in its actual form, end-around carries are frequently achieved without the need of logic or level inversion. The 74LS83 multiplies the input carry by two 4-bit binary words (A and B). On the sum outputs (1?4) and outgoing carry (C4) outputs, the binary sum shows. 74LS83 Datasheet

DS1225AB-70+
The DS1225AB and DS1225AD are 65,536-bit nonvolatile SRAMs that are structured as 8192 words by 8 bits. Each NV SRAM contains its own lithium energy source as well as control circuitry that constantly monitors VCC for out-of-tolerance conditions. When this occurs, the lithium energy source is automatically activated, and write protection is enabled unconditionally to avoid data corruption. The NV SRAMs can be used in place of existing 8k ? 8 SRAMs that are directly compatible with the common bytewide 28-pin DIP standard. The devices also have the same pinout as the 2764 EPROM and 2864 EEPROM, allowing for straightforward replacement while improving performance. The number of write cycles that can be performed is not limited, and no additional support circuitry is required for microprocessor connection.
