Product Overview
The SN74LS136N is a quad 2-input exclusive-OR gate with open-collector outputs from Texas Instruments. It features Schottky-clamped transistors for high speed and is designed for use in systems requiring high noise immunity and low power consumption. The open-collector outputs allow wired-OR connections and drive lines with higher voltage or current than standard TTL outputs. Housed in a 14-pin PDIP package, this device is ideal for logic level conversion, data comparison, and parity generation/checking.
