74FCT373CTSOG

Latches Overview

The IDT 74FCT373CTSOG is an octal transparent latch featuring tri-state outputs, manufactured using Fast CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 10 MHz. The device provides balanced output drivers with a low-level output current of 48 mA and a high-level output current of -15 mA. It exhibits a typical propagation delay of 6.2 ns at 5 V. The component is housed in a 20-pin SOIC package and functions as a non-inverting bus driver suitable for industrial temperature ranges.

Latches Feature Summary

• Octal transparent latch architecture with tri-state control
• Fast CMOS technology enabling high-speed operation
• Balanced output drivers for reduced system switching noise

Latches Applications

• Memory address latching
• I/O port buffering
• Bus driver implementation

Latches Procurement Notes

Verify the manufacturer designation carefully, as the 74FCT series has been produced by multiple entities including IDT, Renesas, and Texas Instruments. Confirm that the specific suffix matches the required package type and electrical characteristics. Ensure compliance with RoHS directives if applicable to the target assembly process. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Latches Selection Notes

Select this component when an octal latch with tri-state capability is required for high-speed digital systems. It serves as a replacement for older ABT logic families due to its lower power consumption and faster switching speeds. Consider the 20-pin SOIC package constraints and the 4.5 V to 5.5 V operating voltage window during circuit design. Evaluate the 6.2 ns propagation delay against system timing requirements.

Latches Part Context

This part belongs to the FCT (Fast CMOS) logic family, designed to offer performance comparable to Schottky TTL while maintaining CMOS power efficiency. The 74FCT373 variant specifically implements an 8-bit transparent latch function. The CTSOG suffix indicates a commercial temperature range and a specific surface-mount package configuration. This family is widely used in embedded systems requiring reliable data storage and bus isolation.
