74AC373PC

Latches Overview

The Fairchild Semiconductor 74AC373PC is an octal transparent latch with three-state outputs, housed in a 14-pin PDIP package. It operates within a supply voltage range of 2V to 6V and supports data rates up to 90 MHz. The device features low input capacitance of 4.5 pF and static current consumption of 40 µA. Propagation delay is specified at 8.5 ns under standard test conditions.

Latches Feature Summary

• Octal D-type transparent latch architecture for bus-oriented applications
• Three-state outputs enabling direct system bus interfacing
• Buffered positive edge-triggered clock inputs

Latches Applications

• Bus-oriented system data storage
• High-speed digital logic circuits
• CMOS memory interface modules

Latches Procurement Notes

Verify the specific manufacturer designation on the component marking, as Fairchild Semiconductor products are now managed by onsemi. Confirm that the PDIP-14 package matches your PCB footprint requirements. Ensure the operating environment remains within the specified temperature range and voltage limits to maintain signal integrity and performance specifications.

Latches Selection Notes

Select this component when an octal latch with three-state capability is required for bus systems. The AC series offers higher speed than HC variants while maintaining CMOS power efficiency. Verify that the single-ended input and differential output characteristics align with the target circuit design constraints.

Latches Part Context

This part belongs to the 74AC logic family, designed for high-speed CMOS applications. It serves as a functional equivalent to other octal latches like the 74ACT373, though with different drive strengths and voltage thresholds. The PC suffix indicates a plastic dual in-line package suitable for through-hole mounting.

Latches Replacement Considerations

Public confirmed substitute part numbers include CD74AC373E from Texas Instruments.
