74FCT162H244CTPVCT

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74FCT162H244CTPVCT is a 16-bit buffer and line driver belonging to the FCT logic family. It features three-state outputs, bus hold functionality on data inputs, and Ioff support for partial-power-down mode operation. The device operates within an industrial temperature range of -40°C to +85°C with a supply voltage of 5V ± 10%. Key electrical parameters include a propagation delay of 4.1 ns maximum, output skew of 0.5 ns, and balanced 24 mA drive capability. It utilizes a 48-lead SSOP package.
