CY74FCT162244ATPAC

Overview

The CY74FCT162244ATPAC is a 16-bit buffer and line driver from the FCT logic series, manufactured by Texas Instruments. It features TTL-compatible CMOS inputs and three-state outputs, operating within a supply voltage range of 4.5 V to 5.5 V. The device provides high drive capability with output currents of -24 mA (high) and 24 mA (low). Key electrical parameters include a propagation delay of 4.8 ns at 5 V, static current of 5 uA, and maximum power dissipation of 1 W. It is housed in a TSSOP-48 package and supports surface-mount installation across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides non-inverting buffering for 16 input lines with corresponding outputs
• Features three-state output control for bus-oriented applications
• Utilizes TTL-compatible CMOS input technology for system integration

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• High-speed data transmission line driving

Procurement Notes

Verify the specific suffix 'ATPAC' against the manufacturer's official datasheet to confirm pinout and electrical specifications match your design requirements. Note that availability may be limited as this component type can reach end-of-life status; consult the manufacturer for current production status and alternative sourcing options before finalizing procurement plans.

Selection Notes

Select this component when a 16-channel buffer with three-state outputs is required for high-speed digital systems. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage range and the TSSOP-48 package constraints. Consider the 4.8 ns propagation delay and 1 W power dissipation limits during thermal management planning for dense PCB layouts.

Part Context

This part belongs to the Texas Instruments FCT (Fast CMOS Technology) family, designed for high-speed digital applications. It serves as a 16-bit version of the 8-bit FCT buffers, offering increased channel density in a single package. The FCT series is characterized by its compatibility with TTL logic levels while maintaining CMOS low-power characteristics, making it suitable for mixed-logic environments.

Replacement Considerations

Check for direct substitutes such as the PI74FCT162244TA or other FCT-series equivalents from different manufacturers. Verify pin-to-pin compatibility and electrical parameter alignment, particularly output current and propagation delay, before replacing the original component.
