74FCT162244ETPAG8

Overview

The 74FCT162244ETPAG8 is a 16-bit buffer and line driver manufactured by Renesas Electronics. 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, drawing a maximum static current of 5 uA. It provides high-level output current of -32 mA and low-level output current of 64 mA. The component exhibits a propagation delay of 1.5 ns and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides 16-bit buffering capability through four independent channels
• Features three-state outputs for bus-oriented applications
• Operates on standard 5V power supplies with low quiescent current

Applications

• Bus-oriented memory systems
• Clock drivers
• Buffering applications in high-speed digital circuits

Procurement Notes

Verify the specific suffix 'E' against official datasheets to confirm package or temperature variations. Confirm end-of-life status as this series may be discontinued. Ensure RoHS compliance matches project requirements. Check for alternate assembly facilities listed in product change notices. Validate pinout compatibility if replacing existing components.

Selection Notes

Select this component when 16-bit wide data paths require buffering with high drive strength. The FCT series offers faster switching speeds compared to LVC alternatives. Verify that the TSSOP-48 package fits the PCB layout constraints. Ensure the 5V supply rail is stable within the specified tolerance. Consider the 1.5 ns propagation delay for timing closure in high-frequency designs.

Part Context

This part is part of the 74FCT162244T family of 16-bit buffers. It shares functional similarities with other FCT devices but differs in package and specific electrical characteristics. The E suffix typically denotes a specific tape and reel configuration or environmental rating. It serves as a critical interface component between microprocessors and peripheral devices.

Replacement Considerations

Public confirmed substitute part numbers include CY74FCT162244CTPVC and CY74FCT162244TPVC from Texas Instruments.
