74ACT373PC

Latches Overview

The Fairchild Semiconductor 74ACT373PC is an octal transparent latch featuring three-state outputs, designed for bus-organized system applications. It belongs to the 74ACT logic series and operates within a supply voltage range of 4.5V to 5.5V. The device provides eight latches in a single package with TTL-compatible inputs. It utilizes advanced silicon-gate CMOS technology to achieve high-speed performance while maintaining low power consumption. The component is housed in a 20-pin DIP package and supports through-hole mounting.

Latches Feature Summary

• Octal transparent latch architecture with three-state outputs for efficient bus interfacing
• TTL-compatible inputs ensuring compatibility with standard logic families
• Advanced silicon-gate CMOS technology providing high noise immunity and low power consumption

Latches Applications

• Bus-oriented system data storage
• Microprocessor-based system address latching
• High-speed digital signal buffering

Latches Procurement Notes

Verify the specific manufacturer origin as Fairchild Semiconductor or onsemi, noting that Fairchild's semiconductor division was acquired by onsemi. Confirm the package type is strictly 20-pin DIP (N20A) and check for RoHS compliance status relative to production date. Ensure the part number suffix matches the exact pin configuration and material specifications required for your design.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for bus systems. It offers higher speed than standard 74LS equivalents while maintaining similar power characteristics. Consider the 74AC373 if lower power is prioritized over speed, or the 74HC373 for broader voltage compatibility. Verify input drive requirements match the source logic family.

Latches Part Context

The 74ACT373 is part of the 74ACT logic family, which bridges the performance gap between 74ALS and 74AC families. It shares pinouts with other 74-series octal latches like the 74LS373 but offers superior switching speeds. The 'PC' suffix denotes the plastic dual in-line package format commonly used in through-hole PCB designs.

Latches Replacement Considerations

Direct substitutes include the MC74ACT373PC from onsemi. Other compatible options are the SN74ACT373PWR from Texas Instruments and the CD74ACT373M96 from Texas Instruments. Ensure replacement parts maintain the same 20-pin DIP footprint and electrical specifications.
