MC74HC373ADWR2G

Latches Overview

The MC74HC373ADWR2G is an octal transparent latch manufactured by onsemi, belonging to the HC logic series. It features eight non-inverting D-type latches with a 20-pin SOIC-Wide package. The device operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -55 °C to +125 °C. Key electrical parameters include a maximum static current of 4 µA, low-level output current of 32 mA, and high-level output current of -7.8 mA. Propagation delays vary based on voltage: 125 ns at 2 V, 80 ns at 3 V, 25 ns at 4.5 V, and 21 ns at 6 V.

Latches Feature Summary

• Transparent latch operation allows data to pass directly to outputs when enabled.
• Non-inverting polarity maintains signal direction without logical inversion.
• Wide operating temperature range supports harsh environmental conditions.
• Low static current consumption reduces power usage during standby.

Latches Applications

• Parallel-to-serial data conversion circuits
• Register storage for microprocessor interfaces
• Buffering digital signals in control systems

Latches Procurement Notes

Verify the specific suffix ADWR2G against official datasheets to confirm package type and tape-and-reel packaging configuration. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles required for surface-mount assembly processes.

Latches Selection Notes

Select this component when an octal latch with HC-speed performance and wide voltage tolerance is required. Compare propagation delays and output drive capabilities against AC-series alternatives if higher speed is needed. Confirm package dimensions match PCB footprint requirements.

Latches Part Context

This part belongs to the MC74HC373A family of octal transparent latches. It shares functional similarities with other 74HC series logic devices but offers specific timing characteristics suited for general-purpose digital applications. The manufacturer provides ECAD models and detailed specifications for integration into larger electronic designs.

Latches Replacement Considerations

Check for direct pin-compatible substitutes within the same logic family. Verify that alternative parts meet identical voltage, current, and temperature specifications before substitution.
