MC74HC373ADWG

Latches Overview

The MC74HC373ADWG is an octal transparent latch manufactured by onsemi, belonging to the HC logic series. It features eight D-type latches with non-inverting outputs and three-state control. The device operates within a supply voltage range of 2 V to 6 V. Propagation delay varies from 125 ns at 2 V to 21 ns at 6 V. Static current is specified at 4 uA. Low-level output current reaches 32 mA, while high-level output current is -7.8 mA. It is housed in a 20-pin SOIC-Wide package and supports surface mount installation.

Latches Feature Summary

• Transparent latch functionality allowing direct data passage when enabled
• Three-state outputs for bus-oriented system applications
• Non-inverting signal path maintaining input logic levels
• CMOS technology ensuring low static power consumption

Latches Applications

• Bus organization systems requiring address or data latching
• Microcontroller interface circuits for memory addressing
• Digital signal processing data buffering
• Portable battery-powered equipment due to wide voltage operation

Latches Procurement Notes

Verify the specific suffix ADWG confirms the SOIC-Wide-20 package and tube packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure moisture sensitivity level requirements are met for surface mount assembly processes. Cross-reference the exact part number against the latest datasheet revision to validate electrical characteristics and pinout compatibility.

Latches Selection Notes

Select this component when an octal latch with three-state capability is required for CMOS logic interfaces. The HC series offers compatibility with standard CMOS outputs and LSTTL outputs via pull-up resistors. Consider the propagation delay specifications relative to the operating voltage for timing-critical designs. Evaluate the SOIC-Wide package dimensions against available PCB space constraints.

Latches Part Context

This component is part of the MC74HC373A family of octal transparent latches. It shares functional similarities with other 74HC series devices but is distinct from the HCT variant which targets TTL-compatible inputs. The ADWG suffix denotes the specific wide SOIC package and manufacturing traceability. It serves as a digital storage element in sequential logic circuits.

Latches Replacement Considerations

MC74HC373ADTR2G: Tape and reel version of the same logical function and package type. MC74HC373ADTG: TSSOP package alternative requiring footprint modification. MM74HC373SJ: Legacy version currently marked as obsolete.
