MM74C373N

Latches Overview

The MM74C373N is a CMOS octal D-type transparent latch featuring three-state outputs, manufactured by onsemi. It operates within a supply voltage range of 3V to 15V and utilizes a 20-pin dual-in-line package (PDIP) with 0.300-inch pin centers. The device provides eight storage elements in a single package, designed for bus-organized systems. Propagation delay ranges from 70ns to 390ns depending on load capacitance and voltage. It offers high noise immunity and low power consumption.

Latches Feature Summary

• CMOS technology providing wide supply voltage range and low power consumption
• Three-state outputs capable of driving high capacitive loads and standard TTL
• Transparent latch operation where outputs follow inputs when Latch Enable is high
• Single control input for both data latching and output disabling

Latches Applications

• Data bus interfacing elements
• Octal LED indicator drivers with blanking capabilities
• Bus monitoring circuits
• Microprocessor front panel displays

Latches Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering code matches the required package type. Check for RoHS compliance status as specifications may vary by production batch. Ensure the device meets the environmental temperature requirements for the intended application environment before finalizing procurement decisions.

Latches Selection Notes

Select this component for applications requiring an octal latch with high drive capability and wide voltage tolerance. Consider the propagation delay variations under different load conditions. Evaluate the package size benefits compared to alternative configurations. Ensure the design accounts for the specific setup and hold time requirements relative to the clock signal frequency.

Latches Part Context

This part belongs to the MM74C series of complementary MOS logic devices. It is functionally paired with the MM74C374 flip-flop in the same datasheet documentation. The device represents a standard solution for parallel data storage in digital systems, offering a compact footprint relative to older packaging technologies while maintaining compatibility with standard logic families.

Latches Replacement Considerations

Direct substitutes include other manufacturers' versions of the 74C373 octal latch. Verify pinout compatibility and electrical characteristics such as propagation delay and output current drive. Ensure the replacement supports the required operating voltage range and package dimensions for board integration.
