SN74AS757DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS757DW is an octal buffer and line driver from the Texas Instruments AS logic series, housed in a 20-pin Small-Outline (DW) package. It features two independent non-inverting functions with open-collector outputs designed to drive bus lines or memory address registers. The device 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. Key electrical characteristics include a low-level output current capability of 64 mA and propagation delays ranging from 1 ns to 21 ns depending on the signal path.
