SN74HCT645PW TI Bus Transceiver | 20-TSSOP | 8-Bit, Non-Inverting

Product Overview

The SN74HCT645PW is a high-performance octal bus transceiver from Texas Instruments, designed for asynchronous two-way communication between data buses. It features 8-bit non-inverting buffers with three-state outputs, enabling bidirectional data flow with direction control (DIR) and output enable (OE) pins. Operating from a 4.5V to 5.5V supply, it is compatible with TTL levels and offers high noise immunity. Housed in a compact 20-TSSOP package, it is ideal for space-constrained applications requiring reliable data transfer.
