SN74AS245N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS245N is an octal bus transceiver manufactured by Texas Instruments, designed for asynchronous bidirectional data communication between two buses. It features eight non-inverting channels with three-state outputs housed in a 20-pin plastic dual in-line package (PDIP). The device operates within a temperature range of 0°C to 70°C and utilizes AS-TTL logic levels. Control inputs manage data direction and output enablement, allowing efficient bus isolation and signal routing in digital systems.
