74AHC373D,118

Latches Overview

The Nexperia 74AHC373D,118 is an octal D-type transparent latch with 3-state outputs housed in a SO20 plastic small outline package (SOT163-1). 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 overvoltage tolerant inputs up to 5.5 V, Schmitt-trigger action on all inputs, and balanced propagation delays. 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

• Octal D-type transparent latch with 3-state outputs controlled by latch enable and output enable inputs
• Overvoltage tolerant inputs allowing direct interface with voltages higher than the supply voltage
• Schmitt-trigger action on all inputs for tolerance of slower rise and fall times
• Latch-up performance exceeding 100 mA per JESD 78 Class II Level A

Latches Applications

• Bus-oriented applications requiring high-impedance states
• Mixed voltage environments utilizing overvoltage tolerant inputs
• Partial power-down applications supported by I_OFF circuitry

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for bus systems. The SO20 package suits designs needing 20 leads with a 7.5 mm body width. Ensure the application voltage remains between 2.0 V and 5.5 V. Consider the -40 °C to +125 °C temperature range for industrial or automotive-grade environments if qualified.

Latches Part Context

This part belongs to the 74AHC logic family, characterized by high-speed CMOS technology and wide supply voltage compatibility. It serves as a digital storage element within integrated circuits, specifically designed for transparent latching operations where data passes through during the enable phase and stores upon transition.

Latches Replacement Considerations

Check for pin-compatible alternatives such as the 74AHC373PW variant which utilizes a TSSOP20 package. Verify that any substitute maintains the same SO20 footprint and electrical specifications if physical replacement is necessary.
