MC74AC373M

Latches Overview

The MC74AC373M is an octal transparent latch with three-state outputs manufactured by onsemi. It belongs to the 74AC logic series and operates within a supply voltage range of 2 V to 6 V. The device features eight D-type latches in a single package, providing non-inverting data paths. Key electrical parameters include a propagation delay of 13.5 ns at 3.3 V and 9.5 ns at 5 V. Static current consumption is specified at 8 uA. Output drive capabilities are rated at 32 mA for low-level output and -24 mA for high-level output. The component supports surface-mount installation in an SOIC-20 package and functions reliably across an operating temperature range from -40 C to +85 C.

Latches Feature Summary

• Octal transparent latch architecture with three-state bus-compatible outputs
• High-speed AC logic performance optimized for system efficiency
• Wide supply voltage operation supporting multiple logic levels

Latches Applications

• Bus-oriented system applications requiring data storage
• Register banks for temporary data holding
• Interface circuits between microprocessors and peripheral devices

Latches Procurement Notes

Verify the specific suffix designation against official datasheets to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact pinout and electrical characteristics required for your design.

Latches Selection Notes

Select this component when designing systems that require high-density data latching with minimal power consumption. The wide voltage range allows compatibility with various logic families. Consider the propagation delay specifications relative to your system clock speed to ensure timing margins are met during data capture operations.

Latches Part Context

This part is a member of the 74AC family, which offers higher speed than standard 74LS logic while maintaining lower power consumption than older CMOS technologies. The octal configuration provides eight independent latches, reducing board space compared to using multiple quadruple latches. It serves as a fundamental building block for digital memory interfaces.

Latches Replacement Considerations

Direct substitutes include SN74AC373N and CD74AC373E from Texas Instruments. Verify pin compatibility and electrical parameter equivalence before substitution.
