CD74LPT16373AMT

Latches Overview

The CD74LPT16373AMT is an octal transparent latch manufactured by Harris Corporation using LPT CMOS technology. It features eight D-type latches with three-state outputs, designed for high-speed bus driving applications. The device operates within a voltage range of 1.65V to 3.6V and supports data rates up to 100 MHz. It includes common latch enable and output enable controls, buffered inputs, and low power consumption characteristics suitable for portable systems.

Latches Feature Summary

• Octal transparent latch configuration with three-state outputs
• Low power consumption utilizing LPT CMOS technology
• High-speed operation supporting 100 MHz data rates
• Compatible with low voltage logic families

Latches Applications

• Portable consumer electronics requiring low power
• Bus-oriented memory address registers
• I/O buffering in battery-powered systems
• High-speed data acquisition systems

Latches Procurement Notes

Verify the manufacturer origin as Harris Corporation or its successors, noting that original Harris logic lines may have been acquired by Intersil or Renesas. Confirm RoHS compliance status, as older Harris parts were often non-compliant. Ensure the suffix 'MT' indicates tape-and-reel packaging if required for automated assembly. Check for obsolescence or lifecycle status given the age of the LPT series.

Latches Selection Notes

Select this component when designing low-voltage (1.65V-3.6V) systems requiring octal latching with high speed. It is suitable for replacing higher voltage 74-series equivalents in modern portable devices. Consider the SSOP-28 package availability and thermal performance. Verify input compatibility with the specific logic family driving the latch inputs to ensure noise immunity and signal integrity at the target operating voltage.

Latches Part Context

The CD74LPT16373AMT belongs to the LPT (Low Power Technology) series from Harris Corporation, designed for low-voltage digital applications. This series bridges the gap between standard CMOS and TTL logic, offering improved speed and lower power than HC/HCT families while maintaining compatibility. The part is functionally similar to other octal latches but optimized for sub-3.3V operation.

Latches Replacement Considerations

Check for equivalents from Intersil or Renesas, which acquired Harris's logic business. Compare pinouts and electrical characteristics carefully, as package variations may exist. Verify that any substitute maintains the 1.65V minimum supply voltage and 100 MHz speed capability.
