SN74AHCT245NSR TI Bus Transceiver | 20-SO | 8-Bit, Non-Inverting, 4.5V-5.5V

Product Overview

The SN74AHCT245NSR is a high-performance octal bus transceiver from Texas Instruments, designed for asynchronous two-way communication between data buses. It operates with a supply voltage range of 4.5V to 5.5V, making it ideal for 5V systems. The device features non-inverting 3-state outputs and is housed in a 20-pin SO package (NSR suffix). With a typical propagation delay of 7.5 ns and low power consumption, it is suitable for high-speed data transfer in industrial and consumer applications.
