74HC373PW-Q100,118

Latches Overview

The Nexperia 74HC373PW-Q100,118 is an octal D-type transparent latch with 3-state outputs, qualified to AEC-Q100 Grade 1 for automotive use. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features CMOS low power dissipation, high noise immunity, and latch-up performance exceeding 100 mA per JESD 78 Class II Level B. Inputs include clamp diodes for interfacing with voltages exceeding VCC. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM).

Latches Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1)
• Wide supply voltage range from 2.0 V to 6.0 V
• High noise immunity and robust latch-up performance
• ESD protection compliant with ANSI/ESDA/JEDEC standards

Latches Applications

• Bus-oriented applications requiring 3-state non-inverting outputs
• Automotive electronic systems
• Mixed voltage environments utilizing input clamp diodes

Latches Procurement Notes

Verify the specific suffix '118' corresponds to the TSSOP-20 package variant SOT360-1 as documented in the ordering information table. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Ensure design inputs respect the absolute maximum ratings for supply voltage and clamping currents to prevent permanent damage.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for bus-oriented designs. The HC logic family provides CMOS compatibility and wide voltage operation suitable for general-purpose digital interfaces. Verify that the TSSOP-20 package dimensions fit the PCB layout constraints and that the thermal derating characteristics are adequate for the expected power dissipation levels.

Latches Part Context

This part belongs to the 74HC373-Q100 series of octal D-type transparent latches manufactured by Nexperia USA Inc. It shares functional similarities with other variants like the 74HCT373PW-Q100 but differs in input level specifications. The PW suffix indicates the TSSOP20 plastic thin shrink small outline package, while the Q100 designation confirms its automotive grade qualification status.

Latches Replacement Considerations

The 74HCT373PW-Q100 serves as a parameter-equivalent alternative within the same product family, offering TTL-compatible input levels instead of CMOS levels.
