CY74FCT162244CTPAC

Overview

The CY74FCT162244CTPAC is a 16-bit buffer and line driver manufactured by Cypress Semiconductor. It features three-state outputs and operates within a voltage range of 4.5V to 5.5V. The device utilizes FCT technology for high-speed performance with low power consumption. It is housed in a 48-pin TSSOP package with a 0.240-inch width. Key electrical characteristics include a typical propagation delay of 4.1 ns and balanced output drivers capable of 24 mA current. The component supports an industrial temperature range from -40°C to +85°C.

Feature Summary

• Balanced output drivers reduce system switching noise and minimize ground bounce.
• Ioff circuitry enables partial power-down mode by preventing backflow current.
• Edge rate control circuits improve noise immunity and signal integrity.
• Bus-hold functionality on data inputs eliminates the need for external pull-up or pull-down resistors.

Applications

• Memory bus driving applications
• Clock distribution networks
• High-speed and low-power bus interface systems
• Driving transmission lines and high capacitive loads

Procurement Notes

Verify the specific suffix 'CTPAC' against official Cypress documentation to confirm the exact package type, tape-and-reel quantity, and environmental compliance status. Ensure the source document explicitly lists this full part number to avoid confusion with similar variants like CY74FCT162H244 or CY74FCT16244. Cross-reference the manufacturer's latest datasheet for any pinout or electrical specification updates.

Selection Notes

Select this component when designing systems requiring 16-bit buffering with controlled edge rates to mitigate electromagnetic interference. The balanced drive capability makes it suitable for applications sensitive to ground bounce. Consider the TSSOP-48 package constraints for board layout. Verify that the 4.5V to 5.5V supply range aligns with the system's power architecture and that the -40°C to +85°C operating range meets environmental requirements.

Part Context

This device belongs to the FCT (Fast CMOS) logic family, designed for high-speed digital applications. It serves as a bridge between different logic levels or buffers signals across long traces. The 16-bit configuration allows for parallel data handling, reducing the number of components needed compared to smaller bit-width drivers. It is commonly used in computer peripherals and communication interfaces.
