SN74AHC245NS TI Bus Transceiver | 20-SO | 8-Bit, Non-Inverting, 2V to 5.5V

Product Overview

The SN74AHC245NS is a high-performance octal bus transceiver from Texas Instruments, designed for bidirectional asynchronous communication between two data buses. Housed in a 20-pin SO package, this device operates over a wide supply voltage range of 2V to 5.5V, making it suitable for both 3.3V and 5V systems. It features non-inverting outputs and 8-bit data paths with direction control (DIR) and output enable (OE) inputs. The SN74AHC245NS is part of TI's AHC family, offering low power consumption and high noise immunity.
