SN74AUCH32244ZKER

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUCH32244ZKER is a 32-bit buffer/driver with 3-state outputs from the Widebus+ family. It operates at 0.8-V to 2.7-V VCC, optimized for 1.65-V to 1.95-V. Key electrical parameters include a maximum propagation delay of 1.8 ns at 1.8 V, ±8-mA output drive at 1.8 V, and max ICC of 40 µA. It features Ioff support for partial-power-down mode and bus hold on data inputs. The device uses a GKE (LFBGA) package.
