74AC373MTC

Latches Overview

The onsemi 74AC373MTC is an octal transparent latch with 3-STATE outputs, housed in a 20-Lead Thin Shrink Small Outline Package (TSSOP). It operates within a supply voltage range of 2.0V to 6.0V and supports an operating temperature from -40°C to +85°C. The device features eight D-type latches where data enters when the Latch Enable (LE) input is HIGH. Outputs are controlled by the Output Enable (OE) input; OE LOW enables standard outputs, while OE HIGH places them in a high impedance state. Propagation delays for data inputs to outputs range from 1.5ns to 15.0ns depending on voltage and load conditions.

Latches Feature Summary

• Contains eight D-type latches with 3-STATE outputs suitable for bus organized system applications
• Outputs source and sink up to 24 mA for robust driving capability
• Latch Enable (LE) controls transparency, allowing data storage upon transition to LOW
• Output Enable (OE) manages output states between standard logic levels and high impedance

Latches Applications

• Bus organized system applications requiring data storage and buffering
• Digital systems utilizing 3-STATE outputs for shared signal lines
• Octal data latching in microprocessor-based designs

Latches Procurement Notes

Verify the specific package type matches the design requirements, as this component is available in multiple form factors including SOIC, SOP, and PDIP. Confirm that the ordering suffix corresponds to the desired packaging format, such as tape and reel options if applicable. Ensure compatibility with the target voltage range and temperature specifications before finalizing procurement decisions.

Latches Selection Notes

Select this component for applications requiring octal latching with tri-state control capabilities. Consider the propagation delay characteristics relative to system timing requirements. Evaluate the drive strength against load capacitance needs. Compare against other series members like the ACT variant if TTL-compatible inputs are necessary instead of standard AC thresholds.

Latches Part Context

This part belongs to the 74AC family of logic devices, specifically designed for high-speed operation compared to older standards. The MTC designation identifies the 20-lead TSSOP physical package. It serves as a fundamental building block for digital memory and interface circuits within broader semiconductor logic portfolios.

Latches Replacement Considerations

Direct substitutes include other manufacturers' 74AC373 equivalents in the TSSOP-20 package. Verify pinout compatibility and electrical specifications such as supply voltage ranges and output drive currents before substitution.
