MC74LCX373DTR2G

Latches Overview

The MC74LCX373DTR2G is a low-voltage CMOS octal transparent latch with 5 V-tolerant inputs and outputs, manufactured by onsemi. It operates from a 2.3 to 3.6 V supply and contains eight D-type latches with three-state outputs. The device features balanced output sink and source capabilities of 24 mA. Propagation delay ranges from 1.5 ns to 9.6 ns depending on voltage and load conditions. Quiescent supply current is typically 10 µA at 3.6 V. It is housed in a TSSOP-20 package.

Latches Feature Summary

• Features 5 V tolerant inputs and outputs for safe interfacing with 5 V devices.
• Supports live insertion and withdrawal operations.
• Provides high impedance state when VCC is 0 V via IOFF specification.
• Offers near zero static supply current across all logic states.

Latches Applications

• Interface capability with 5 V TTL logic
• LVTTL compatible systems
• LVCMOS compatible systems

Latches Procurement Notes

Verify the specific suffix 'DTR2G' corresponds to the TSSOP-20 tape and reel packaging configuration. Confirm RoHS compliance and Pb-free status as indicated in the ordering information table. Ensure the application environment remains within the specified operating temperature range of -40 °C to +85 °C. Check for any recent PCN updates regarding assembly or material changes.

Latches Selection Notes

Select this component when an octal latch with 5 V tolerance is required for low-voltage applications between 2.3 V and 3.6 V. It is suitable for designs needing balanced 24 mA drive strength and minimal static power consumption. Consider the TSSOP-20 package constraints and ensure input signals do not exceed the absolute maximum ratings during transients.

Latches FAQ

What is the maximum input voltage allowed?

The DC input voltage can range from -0.5 V to +7.0 V according to maximum ratings, with recommended operation up to 5.5 V.

How does the Output Enable (OE) pin function?

When OE is LOW, the standard outputs are enabled. When OE is HIGH, the outputs enter a high impedance state without interfering with data entering the latches.
