74HC245D (Octal Bus Transceiver- 3 State Outputs) SMD

Overview

The 74HC245D is a high-speed CMOS Octal Bus Transceiver designed for bidirectional asynchronous communication between two data buses. Featuring three-state non-inverting outputs, this SMD component is essential for bus-oriented systems where data direction control and high-impedance states are required. Manufactured using silicon-gate CMOS technology, it achieves the low power dissipation of standard CMOS while operating at speeds comparable to LSTTL.
