SN74AHCT245N TI Bus Transceiver | 20-PDIP | 8-Bit, Non-Inverting, 4.5V-5.5V

Product Overview

The SN74AHCT245N 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 3-state outputs, enabling bidirectional data flow controlled by direction (DIR) and output enable (OE) inputs. Operating from 4.5V to 5.5V, it is compatible with TTL levels and offers high drive capability up to 8 mA. Housed in a 20-pin PDIP package, it is ideal for through-hole PCB designs requiring robust signal translation.
