CY74FCT162244TPVCT

Overview

The CY74FCT162244TPVCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic family. It features non-inverting logic with three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a 48-pin SSOP package for surface-mount installation. Key electrical characteristics include a typical propagation delay of 4.1 ns at 5 V, with output drive capabilities specified as 32 mA source current and 64 mA sink current. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Incorporates Ioff circuitry to support partial power-down mode operation by disabling outputs and preventing backflow current during power loss.
• Features edge-rate control circuits designed to significantly improve noise characteristics and reduce system switching noise.
• Provides balanced output drivers that minimize undershoot and ground bounce without requiring external termination resistors.

Applications

• Memory bus interface applications
• Clock signal distribution systems
• High-speed low-power bus interfaces
