CY74FCT16244TPACT

Overview

The CY74FCT16244TPACT is a 16-bit buffer and line driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features three-state outputs. The device provides high drive capability with output currents of -32 mA for high level and 64 mA for low level. Propagation delay is specified at 6.5 ns at 5 V, with a maximum power dissipation of 1 W. It is housed in a TSSOP-48 package and supports surface mount installation.

Feature Summary

• Provides non-inverting buffering for 16 input lines
• Features three-state outputs for bus driving applications
• Delivers high current drive capability for signal integrity

Applications

• High-speed data bus buffering
• Clock distribution networks
• Memory interface drivers

Procurement Notes

Verify the specific suffix 'TPACT' against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the component status is reviewed as availability may vary. Confirm RoHS compliance details directly from the latest documentation before finalizing procurement decisions.

Selection Notes

Select this component when a 16-channel non-inverting buffer with three-state control is required. It is suitable for systems operating between 4.5 V and 5.5 V. Consider the TSSOP-48 package constraints and the 6.5 ns propagation delay relative to system timing budgets. Verify thermal management needs given the 1 W power dissipation rating.

Part Context

This part belongs to the FCT logic family, designed for CMOS compatibility with TTL input levels. It serves as a high-performance alternative to standard logic buffers, offering improved switching speeds and drive strength. The 16-bit configuration reduces board space compared to using multiple octal devices.

Replacement Considerations

Check for direct substitutes such as the 74FCT16244CTPVCT or CY74FCT16244ATPACT. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
