74FCT162244CTPVG

Overview

The IDT 74FCT162244CTPVG is a high-speed, low-power CMOS bus driver belonging to the 74FCT logic series. It features sixteen non-inverting outputs organized into four functional blocks of four bits each. The device utilizes a 48-pin TSSOP surface-mount package with a 0.50 mm pin pitch. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels while providing TTL-compatible output levels. Key electrical characteristics include a maximum propagation delay of 3.5 ns at 50 pF load, with output drive capabilities of -24 mA for high state and 24 mA for low state.

Feature Summary

• Provides sixteen non-inverting buffered outputs for signal transmission
• Supports live insertion via power-off disable functionality
• Offers high electrostatic discharge protection exceeding 2000V per MIL-STD-883

Applications

• High-speed data bus buffering in computing systems
• Clock distribution networks requiring low skew
• Memory interface drivers for parallel data paths

Procurement Notes

Verify the specific suffix 'CTPVG' against official manufacturer documentation to confirm package type, temperature grade, and lead finish specifications. Ensure compatibility with existing PCB footprints for the 48-pin TSSOP configuration. Confirm RoHS compliance status if required by project regulations, as manufacturing processes may vary across different production runs or legacy stock sources.

Selection Notes

Select this component when designing systems requiring fast, non-inverting buffer functions with moderate drive strength. The 74FCT series serves as a direct replacement for older ABT logic families while offering improved speed and lower power consumption. Consider the 48-pin TSSOP package constraints regarding board space and thermal management during layout planning.

Part Context

This part belongs to the Integrated Device Technology (IDT) 74FCT family of fast CMOS logic devices. These components are engineered to replace faster bipolar technologies like ABT while maintaining CMOS power efficiency. The 74FCT162244 specifically addresses applications needing wide bus buffering with tri-state control capabilities.

Replacement Considerations

Texas Instruments offers the CY74FCT162244CTPVC as a parameter-equivalent alternative. Verify pinout compatibility and electrical specifications before substitution.
