74FCT16244CTPVG8

Overview

The IDT 74FCT16244CTPVG8 is a 16-bit buffer and line driver belonging to the FCT logic series. It features four independent input lines and four output lines with non-inverting polarity. The device utilizes TSSOP-48 packaging for surface mount installation. Electrical characteristics include a high-level output current of -32 mA and a low-level output current of 64 mA. Static current consumption is specified at 5 uA, while operating supply current reaches 6.4 mA. The unit operates within a voltage range of 4.5 V to 5.5 V and supports a propagation delay of 1.5 ns across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides high-drive capability with asymmetric output currents for robust signal transmission
• Offers three-state outputs to facilitate bus sharing and system isolation
• Integrates power-off disable functionality to permit live insertion without electrical interference

Applications

• High-speed data buffering in parallel communication architectures
• Line driving for memory interface buses
• Signal distribution in industrial control systems requiring live insertion support

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status and specific package markings against official datasheets before integration. Ensure supply chain stability as this component may be subject to end-of-life notices or manufacturing transitions. Validate pin compatibility with existing PCB footprints during procurement planning.

Selection Notes

Select this component when designing systems requiring 16-bit wide buffering with high drive strength. The FCT technology offers a CMOS replacement for older ABT functions with improved speed and lower power. Consider the TSSOP-48 package dimensions for board space constraints. Evaluate the 1.5 ns propagation delay against system timing requirements to ensure signal integrity is maintained.

Part Context

This part belongs to the IDT 74FCT16244T family, which includes variants like AT, CT, and ET suffixes indicating different temperature ranges or packaging options. The FCT series represents Fast CMOS technology designed for high-performance digital applications. Renesas Electronics currently manufactures these devices following the acquisition of IDT's logic business, maintaining the original functional specifications.

Replacement Considerations

Cross-reference with IDT74FCT162H244ETPA for similar quad 4-bit driver configurations. Verify pinout compatibility with other 74FCT16244 variants from manufacturers such as Texas Instruments or Renesas. Ensure that substitute components maintain the same 3-state output behavior and drive current capabilities.
