SNJ54HC645FK TI Bus Transceiver | Octal | 2V-6V, 8mA

Product Overview

The SNJ54HC645FK is a high-speed octal bus transceiver from Texas Instruments, designed for bidirectional asynchronous communication between two data buses. It features non-inverting 3-state outputs and operates over a wide voltage range of 2V to 6V. The device is ideal for driving heavily loaded buses with up to 8mA output current per channel. Housed in a ceramic flatpack (FK) package, it is specified for the military temperature range (-55°C to +125°C), ensuring reliable performance in harsh environments.
