SN74AHC245N TI Bus Transceiver | 20-PDIP | 8-Bit, Non-Inverting, 2V to 5.5V

Product Overview

The SN74AHC245N is an octal bus transceiver from Texas Instruments (TI) designed for asynchronous two-way communication between data buses. It features 8-bit non-inverting buffers with 3-state outputs, allowing bidirectional data flow controlled by direction (DIR) and output enable (OE) inputs. Housed in a 20-pin PDIP package, this device operates over a wide supply voltage range of 2V to 5.5V, making it suitable for interfacing with both 3.3V and 5V logic systems. The SN74AHC245N is part of TI's AHC family, offering high-speed performance with low power consumption.
