74HC373DTR2G

Latches Overview

The onsemi 74HC373DTR2G is an octal 3-state non-inverting transparent latch manufactured using high-performance silicon-gate CMOS technology. It operates within a DC supply voltage range of 2.0 V to 6.0 V and supports an operating temperature from -55°C to +125°C. The device features eight D-type inputs and corresponding outputs, with propagation delays ranging from 21 ns to 190 ns depending on voltage and temperature. It provides an output drive capability equivalent to 15 LSTTL loads and includes low input current characteristics.

Latches Feature Summary

• Transparent data latching when the Latch Enable signal is high, capturing data upon transition to low
• Three-state outputs controlled by the Output Enable pin for bus-driven applications
• High noise immunity and ESD protection rated at 2000 V (HBM) and 200 V (Machine Model)
• Direct interface compatibility with CMOS, NMOS, and TTL logic families

Latches Applications

• Bus-oriented memory mapping
• Clock buffering
• Bus drivers

Latches Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the TSSOP-20 package and tape-and-reel shipping configuration. Confirm RoHS compliance status as indicated in the datasheet documentation. Ensure the component matches the exact manufacturer part number to avoid functional discrepancies associated with different package types or speed grades.

Latches Selection Notes

Select this component for designs requiring octal data storage with tri-state control. Consider the 2.0 V to 6.0 V operating range for flexibility in system power supplies. Evaluate the propagation delay specifications against the target clock frequency requirements. Verify that the TSSOP-20 package dimensions fit the available PCB real estate constraints.

Latches Part Context

This device belongs to the 74HC series of high-speed CMOS logic integrated circuits. It serves as a standard octal latch solution compatible with industry-standard pinouts similar to older LS logic families. The product line emphasizes performance improvements while maintaining backward compatibility for design migration purposes.

Latches Replacement Considerations

Check for alternative packages such as SOIC if lead-free soldering profiles differ. Verify if other manufacturers offer functionally equivalent parts with identical pinouts and electrical characteristics for supply chain diversification.
