74LCX16374MEAX

Overview

The Fairchild Semiconductor 74LCX16374MEAX is a 16-bit D-type flip-flop with 3-state outputs, designed for low-voltage applications. It operates within a supply voltage range of 2.3V to 3.6V and features 5V tolerant inputs and outputs. The device utilizes advanced CMOS technology to achieve high-speed performance with low power consumption. Key electrical characteristics include a maximum propagation delay of 4.5ns and a quiescent current of 10µA. It is housed in a 48-lead TSSOP package, suitable for surface-mount assembly.

Feature Summary

• Provides 16-bit data storage with independent 3-state output control
• Features 5V tolerant I/Os compatible with mixed voltage systems
• Utilizes patented noise reduction circuitry for EMI suppression

Applications

• Memory address drivers
• Clock distribution networks
• Bus-oriented transmitter/receiver circuits

Procurement Notes

Verify the specific suffix 'MEA' against the manufacturer's official datasheet to confirm package dimensions and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering information with the latest Fairchild or ON Semiconductor product change notices to avoid obsolete variants.

Selection Notes

Select this component when designing low-voltage logic interfaces requiring 16-bit parallel data latching. It is appropriate for systems operating at 3.3V where 5V signal compatibility is necessary. Consider the 48-lead TSSOP footprint during PCB layout planning to ensure adequate thermal dissipation and trace routing space for high-density designs.

Part Context

This part belongs to the LCX family of low-voltage CMOS logic devices. It serves as a 16-bit variant within the 74LCX374 series, offering higher density than standard 8-bit counterparts. The LCX series is engineered for portable electronics and battery-powered devices due to its extended voltage range and reduced power profile compared to older LS or HC families.
