SN74AS641DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS641DWR is an octal bus transceiver from the Texas Instruments AS logic series, designed for asynchronous two-way communication between data buses. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device features true logic polarity with bidirectional data transfer controlled by a DIR input and isolation via an OE input. It utilizes a 20-pin Small-Outline (DW) package.
