74FCT373PCTQ

Latches Overview

The IDT 74FCT373PCTQ is an octal transparent latch manufactured by Integrated Device Technology Inc. It belongs to the FCT logic series and features eight non-inverting outputs with tri-state capability. The device operates within a supply voltage range of 4.75 V to 5.25 V. It exhibits a propagation delay of 5.2 ns at 5 V and provides output drive currents of 32 mA for both high and low states. The component supports surface mount installation in a QSOP-20 package and functions reliably across an operating temperature range from -40°C to +85°C.

Latches Feature Summary

• Provides eight-bit data storage with transparent latch functionality
• Features tri-state outputs for bus-oriented memory applications
• Supports power-off disable to prevent floating outputs

Latches Applications

• Bus-oriented memory register implementations
• Temporary storage of digital data in communication systems
• Interface circuits requiring tri-state buffering

Latches Procurement Notes

Verify the manufacturer designation as IDT or Integrated Device Technology Inc, noting historical corporate acquisitions. Confirm the specific suffix PCTQ corresponds to the QSOP-20 package type and bulk packaging format. Ensure the component meets RoHS compliance requirements if specified for your project. Cross-reference the datasheet revision to confirm electrical characteristics match your design constraints.

Latches Selection Notes

Select this component when an octal latch with tri-state control is required for 5V CMOS logic systems. Consider the 5.2 ns propagation delay for timing-sensitive designs. Evaluate the QSOP-20 package dimensions against available PCB space. Verify that the 32 mA output current capability meets the load requirements of the connected circuitry without exceeding thermal limits.

Latches Part Context

This part belongs to the FCT (Fast CMOS) logic family, designed for high-speed operation with CMOS power consumption. The 74FCT373 variant specifically provides octal latching with tri-state outputs. IDT was a prominent provider of high-performance semiconductor solutions before being acquired by Renesas Electronics. This component serves as a standard interface element in digital logic designs requiring parallel data retention.

Latches Replacement Considerations

The CY74F373ATQCT from Texas Instruments offers similar octal latch functionality in a QSOP-20 package. Verify pin compatibility and electrical specifications before substitution. Check for differences in propagation delay and output drive strength to ensure system performance remains unaffected.
