74AHC373PW,118

Latches Overview

The Nexperia 74AHC373PW,118 is an octal D-type transparent latch with 3-state outputs housed in a TSSOP20 (SOT360-1) package. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features balanced propagation delays, Schmitt-trigger action on all inputs, and overvoltage tolerant inputs up to 5.5 V. Static characteristics include a maximum input leakage current of 2.0 μA at -40 °C to +125 °C and a typical power dissipation capacitance of 10 pF.

Latches Feature Summary

• Features overvoltage tolerant inputs that accept voltages higher than the supply voltage, enabling use as translators in mixed voltage environments.
• Includes latch enable (LE) and output enable (OE) inputs for controlling data transparency and high-impedance OFF-states.
• All inputs have Schmitt-trigger action to provide high noise immunity.
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level A.

Latches Applications

• Bus-oriented applications requiring 3-state non-inverting outputs
• Mixed voltage translation environments due to overvoltage tolerant inputs
• Data storage and register operations using transparent latch functionality

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for bus-oriented designs. The TSSOP20 package offers a compact footprint suitable for space-constrained PCB layouts. Ensure the application voltage remains within the 2.0 V to 5.5 V range and consider the -40 °C to +125 °C operating temperature specification for industrial or automotive-grade environments if applicable.

Latches Part Context

This part belongs to the 74AHC series of CMOS logic devices, specifically designed for low power dissipation and high noise immunity. The 74AHC373 variant provides eight independent D-type latches with a common latch enable and a common 3-state output enable. It is functionally compatible with other 74AHC family members but distinguished by its latch configuration rather than simple gates or flip-flops.
