74FCT162244ATPVG

Overview

The 74FCT162244ATPVG is a 16-bit buffer and line driver manufactured by Renesas Electronics Corporation. It belongs to the FCT logic series and features non-inverting polarity with three-state outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface mount installation in a 48-pin SSOP package. It provides an output current capability of 24 mA for both high and low states, with a propagation delay of 4.8 ns at nominal supply. The component functions across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides 16-bit buffering with non-inverting signal transmission
• Features three-state outputs for bus line isolation
• Supports 24 mA drive strength for reliable signal integrity

Applications

• Parallel data bus buffering in computer systems
• Clock distribution networks requiring high drive capability
• Memory interface drivers for address and data lines

Procurement Notes

Verify the specific suffix 'TPVG' against official Renesas documentation to confirm pinout and electrical characteristics, as suffixes often denote package type or tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 48-SSOP form factor. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before procurement.

Selection Notes

Select this component when a 16-bit wide buffer with moderate speed and high drive current is required. The FCT technology offers faster switching than standard LS logic while maintaining CMOS input compatibility. Consider the 4.5V to 5.5V operating range and ensure the system power supply aligns with these limits. Evaluate thermal performance if multiple units are placed closely on the board.

Part Context

This part is part of the 74FCT162244 family of 16-bit buffers. Similar variants include the 74FCT162244ATPF and 74FCT162244ATPAG8, which may differ in packaging or reel specifications. The FCT series is designed for applications requiring fast propagation delays and strong output drive capabilities compared to older logic families.

Replacement Considerations

Publicly confirmed substitute part numbers include 74FCT162244CTPVCT from Texas Instruments and CY74FCT162244CTPVC from Cypress Semiconductor. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
