SN74AC373NE4

Latches Overview

The SN74AC373NE4 is an octal D-type transparent latch with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and accepts input voltages up to 6V. The device features a maximum propagation delay of 9.5ns at 5V. It utilizes a 20-pin PDIP package for through-hole mounting.

Latches Feature Summary

• Features 3-state noninverting outputs designed to drive bus lines directly.
• Provides full parallel access capability for data loading.
• Includes a buffered output-enable input to control high-impedance states.

Latches Applications

• Implementing buffer registers
• Configuring I/O ports
• Bidirectional bus drivers
• Working registers

Latches Procurement Notes

Verify the specific ordering suffix 'E4' against current manufacturer documentation to confirm lead finish and RoHS compliance status, as packaging options may vary. Confirm that the PDIP-20 package aligns with your board assembly requirements before finalizing procurement.

Latches Selection Notes

Select this component when designing systems requiring octal latching with bus-compatible 3-state outputs. Ensure the operating voltage falls between 2V and 6V. Consider the 9.5ns propagation delay at 5V for timing constraints in your circuit design.

Latches Part Context

This part belongs to the SNx4AC373 family of octal D-type transparent latches with 3-state outputs. The 'SN74' prefix indicates commercial temperature range operation (-40°C to +85°C), while the 'AC' series denotes advanced CMOS technology optimized for speed and power consumption.

Latches Replacement Considerations

Direct substitutes include other variants within the SN74AC373 family such as SN74AC373N or SN74AC373NSR, provided the package type matches the PCB footprint. Verify pinout compatibility and electrical specifications before substitution.
