74LCX16373GX

Latches Overview

The Fairchild Semiconductor 74LCX16373GX is a low-voltage CMOS 16-bit transparent latch featuring non-inverting outputs. It operates within a supply voltage range of 2.0 V to 3.6 V, ensuring compatibility with modern low-power digital systems. The device utilizes advanced silicon-gate CMOS technology to achieve high noise immunity and low power consumption. Propagation delays are specified at 5.9 ns at 2.7 V and 5.4 ns at 3.3 V. It includes guaranteed latch-up protection exceeding 100 mA per JESD 78 standards and supports hot insertion without destructive effects.

Latches Feature Summary

• Transparent data latching controlled by a dedicated Latch Enable input for byte-oriented applications
• High-impedance glitch-free bus loading maintained throughout the entire power-up and power-down cycle
• Non-destructive hot insertion capability allowing safe connection while the system is active
• Robust ESD protection and guaranteed latch-up performance exceeding industry stress standards

Latches Applications

• Bus-oriented memory mapping and address latching in portable electronic devices
• Data buffering and storage in battery-powered consumer electronics
• Interface circuits between microprocessors and peripheral logic components
• Byte-controlled data acquisition systems requiring low-voltage operation

Latches Procurement Notes

Verify the specific suffix 'GX' against official onsemi/Fairchild documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing process. Cross-reference the manufacturer part number with current lifecycle status to confirm availability and obsolescence warnings before finalizing procurement plans.

Latches Selection Notes

Select this component when designing systems requiring 16-bit parallel data storage with low-voltage compatibility. It is suitable for applications needing high-speed latching with minimal power dissipation. Consider the TSSOP or similar surface-mount package options available under this part number for space-constrained PCB layouts. Verify that the operating temperature range aligns with your environmental specifications.

Latches Part Context

This device belongs to the 74LCX family of low-voltage CMOS logic integrated circuits. The LCX series is designed to bridge the gap between older 5V TTL-compatible logic and modern 3.3V and 2.5V systems. It offers improved speed and lower power consumption compared to standard HC or HCT families while maintaining pin-out compatibility with legacy designs.

Latches Replacement Considerations

Direct substitutes include the MC74LCX16373 from onsemi. Other compatible alternatives may include the SN74LCX16373 from Texas Instruments or the ALVC16373 from NXP, provided voltage levels and package types match.
