74AHCT373D,112

Latches Overview

The Nexperia 74AHCT373D,112 is an octal D-type transparent latch with 3-state outputs housed in a SO20 plastic small outline package (SOT163-1). It operates within a supply voltage range of 2.0 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, allowing use as translators in mixed-voltage environments. Static characteristics specify input leakage current at 2.0 μA maximum under extreme conditions.

Latches Feature Summary

• Octal D-type transparent latch architecture with common 3-state output enable control
• Overvoltage tolerant inputs compatible with voltages exceeding the supply rail
• Schmitt-trigger action on all inputs for improved noise immunity
• ESD protection compliant with ANSI/ESDA/JEDEC JS-001 class 2 and JS-002 class C3 standards

Latches Applications

• Data storage registers in digital logic circuits
• Bus interface applications requiring latching functionality
• Mixed-voltage translation between different logic families

Latches Procurement Notes

Verify the specific ordering suffix '112' against the manufacturer's official documentation to confirm the exact tape-and-reel or tube packaging configuration intended for your assembly process. Confirm that the component status remains active or qualified for new designs, as discontinuation notices may affect long-term availability. Ensure compliance with RoHS directives and REACH regulations relevant to your target market before finalizing procurement orders.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for high-speed data handling. The AHCT series ensures TTL-compatible input levels while maintaining CMOS performance. Verify that the operating voltage range of 2.0 V to 5.5 V aligns with your system power rails. Consider the SO20 package dimensions if board space constraints are critical compared to alternative packages like TSSOP.

Latches Part Context

This part belongs to the 74AHC family of high-speed CMOS logic devices manufactured by Nexperia. It serves as the octal latch counterpart within the broader 74-series logic ecosystem. The device provides eight independent D-type latches with transparent operation controlled by a latch enable signal and tri-state outputs managed by a separate output enable input.

Latches Replacement Considerations

Direct substitutes include the 74AHCT373PW variant which utilizes a TSSOP20 package instead of SO20. Other manufacturers offer equivalent octal D-type latches with 3-state outputs, but pin compatibility and electrical specifications must be verified against the original datasheet requirements.
