SN74AS756DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS756DWR is an octal buffer and line driver in a 20-pin Small-Outline (DW) package. It features open-collector outputs designed to drive bus lines or buffer memory address registers, eliminating the need for three-state overlap protection. The device operates with a supply voltage of 4.5 V to 5.5 V and supports an operating free-air temperature range of 0°C to 70°C. It utilizes pnp inputs to reduce DC loading and offers high fan-out and improved fan-in capabilities.
