74LS136 DIP Quad 2-Input Exclusive-OR Gate With Open-Collector Outputs
The 74LS136 is a high speed TTL integrated circuit containing four independent 2-input Exclusive-OR (XOR) gates. This specific version features open-collector outputs, which differ from standard totem-pole outputs by requiring an external pull-up resistor to achieve a logic high state. This architecture allows for wired-AND logic applications and enables the device to interface with different voltage levels or drive heavier loads.
The XOR logic function provides a high output only when the two inputs are at different logic levels. With the open-collector configuration, these gates are ideal for implementing digital comparators, parity generators, and error detection circuits where multiple outputs need to be tied to a single line. The low power Schottky technology ensures high speed switching while maintaining the flexibility provided by the open-collector design.
