MC74LCX373DTG

Latches Overview

The MC74LCX373DTG is a low-voltage CMOS octal transparent latch manufactured by onsemi. It operates from a 2.0 V to 3.6 V supply and features 5 V tolerant inputs and outputs, allowing safe interfacing with 5 V logic devices. The device contains eight D-type latches with three-state outputs controlled by Latch Enable (LE) and Output Enable (OE) inputs. It provides balanced output sink and source capabilities of up to 24 mA. The component supports live insertion and withdrawal and includes an IOFF specification for high impedance when VCC is 0 V.

Latches Feature Summary

• Features 5 V tolerant inputs and outputs for direct interface with 5 V TTL logic without level shifting.
• Provides balanced 24 mA output drive capability for improved switching noise performance.
• Supports live insertion and withdrawal operations through dedicated control inputs.
• Guarantees high impedance state during power-off conditions via the IOFF specification.

Latches Applications

• Interface between 5 V logic systems and lower voltage CMOS components
• Data storage in memory architectures requiring octal latching
• Bus driver applications utilizing three-state output control

Latches Procurement Notes

Verify the specific package suffix matches the required form factor, as the DT suffix denotes TSSOP-20. Confirm that the procurement channel sources genuine onsemi products to ensure compliance with RoHS and Pb-Free standards. Check for any -Q suffix variants if automotive qualification or AEC-Q100 certification is required for the target application environment.

Latches Selection Notes

Select this component when designing circuits that require octal data latching with mixed voltage domains. It is suitable for applications needing 5 V tolerance on both input and output lines while operating at core voltages between 2.0 V and 3.6 V. Consider the TSSOP-20 package constraints and thermal requirements for surface mount assembly processes.

Latches Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices. It serves as an octal version of the standard 74LS373 latch but optimized for modern low-power applications. The device replaces older bipolar technologies in systems requiring reduced power consumption and higher speed operation within low-voltage environments.

Latches Replacement Considerations

Check for NLV74LCX373DTR2G for automotive qualified versions. Verify pin compatibility with other 74LCX373 derivatives from different manufacturers before substitution.
