74LCX16374MEA

Overview

The onsemi 74LCX16374MEA is a low-voltage 16-bit D-type flip-flop featuring five-state outputs, designed for bus-oriented applications. It operates within a supply voltage range of 2V to 3.6V and supports clock frequencies up to 170 MHz. The device provides high noise immunity and includes an enable function. Key electrical parameters include a maximum propagation delay of 6.2ns at 3.3V with 50pF load, output drive currents of 24mA for both high and low states, and a typical static current of 20µA. It is housed in a 48-TFSOP package.

Feature Summary

• Low voltage operation supporting 2V to 3.6V supply ranges
• High noise immunity suitable for noisy environments
• Five-state outputs for effective bus driving
• Enable function for controlled data latching

Applications

• Bus-oriented data storage applications
• Portable equipment requiring low power consumption
• Battery-powered systems
• High-speed data buffering

Procurement Notes

Verify the specific suffix 'MEA' against official onsemi documentation to confirm package type and tape/reel specifications. Ensure compatibility with design-in requirements regarding operating temperature and voltage levels. Cross-reference with current product availability status as component lifecycles may change. Confirm that the selected variant meets all necessary environmental and regulatory standards for the intended application.

Selection Notes

Select this component for designs requiring 16-bit parallel data storage with low power consumption. It is suitable for systems operating between 2V and 3.6V where high noise immunity is critical. Consider the 48-TFSOP package dimensions for PCB layout constraints. Evaluate the 170 MHz clock frequency capability against system timing requirements to ensure adequate performance margins.

Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices from onsemi. The LCX family is characterized by its ability to operate at lower voltages than standard 5V logic while maintaining compatibility. The 16374 specifically denotes a 16-bit D-type flip-flop configuration, distinguishing it from other logic functions like buffers or gates within the same series.

Replacement Considerations

Public confirmed substitutes include SN74ALVCH16374DGGR from Texas Instruments and SN74LVTH16374DGGR from Texas Instruments. Verify pinout and electrical parameter compatibility before substitution.
