74FCT162827ATPVCT

Buffers, Drivers, Receivers, Transceivers Overview

The CY74FCT162827ATPVCT is a 20-bit buffer and line driver manufactured by Texas Instruments. It operates within an industrial temperature range of -40°C to +85°C with a supply voltage of 5V ± 10%. The device features balanced 24 mA output drivers, providing typical ground bounce (VOLP) of less than 0.6V at 25°C. Propagation delay ranges from 1.5 ns to 5.0 ns depending on load capacitance. It utilizes a 56-lead SSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports partial-power-down mode operation via Ioff circuitry to prevent damaging current backflow when powered down.
• Features edge-rate control circuitry for significantly improved noise characteristics and reduced system switching noise.
• Includes balanced 24 mA output drivers with current-limiting resistors to minimize undershoot and reduce the need for external terminating resistors.

Buffers, Drivers, Receivers, Transceivers Applications

• High-performance bus interface buffering for wide data or address paths
• Driving transmission lines in systems requiring minimal ground bounce
