74LS245 DIP-20 Octal Bidirectional Bus Transceiver IC (3-State Outputs, TTL, 5V)

Description -

The 74LS245 DIP is a TTL logic integrated circuit that functions as an octal bidirectional bus transceiver in a 20-pin Dual Inline Package (DIP). It belongs to the 74LS Low Power Schottky logic family and is designed for high-speed bidirectional data transfer between digital buses in microprocessor and embedded systems.

The device features eight non-inverting bidirectional transceivers with 3-state outputs. Data direction is controlled by the DIR (Direction) input, while the active LOW Output Enable (OE) input places all bus lines into a high-impedance state for efficient bus sharing. The 74LS245 is widely used for memory interfacing, bus buffering, microprocessor systems, and digital communication.
