SN74HCT646NT TI Bus Transceiver | 24-PDIP | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74HCT646NT is a high-speed CMOS octal bus transceiver from Texas Instruments, designed for asynchronous two-way communication between data buses. It features non-inverting 3-state outputs and operates from a 4.5V to 5.5V supply. The device is housed in a 24-pin PDIP package, making it suitable for through-hole PCB assembly. With TTL-compatible inputs and balanced propagation delays, it is ideal for interfacing between different logic families in industrial and automotive systems.
