74HCT373PW-Q100,11

Latches Overview

The Nexperia 74HCT373PW-Q100,11 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 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL input levels, common output enable (OE) and latch enable (LE) controls, and includes clamp diodes on inputs. Packaged in a TSSOP20 (SOT360-1) format, it provides non-inverting outputs suitable for bus-oriented applications.

Latches Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• TTL-compatible input levels for direct interfacing with standard logic
• High noise immunity and low power dissipation characteristics
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Latches Applications

• Bus-oriented data storage systems
• Automotive electronic control units
• Mixed-signal translation interfaces

Latches Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the AEC-Q100 Grade 1 qualification aligns with target automotive reliability requirements. Ensure design margins respect the specified temperature range and voltage limits to maintain functional integrity under all operating conditions.

Latches Selection Notes

Select this component when TTL-level compatibility is required alongside automotive-grade reliability. The 3-state outputs facilitate efficient bus sharing in complex digital architectures. Verify that the TSSOP20 footprint accommodates the available board space constraints while meeting thermal dissipation needs for the intended application environment.

Latches Part Context

This part belongs to the Nexperia 74HCT373-Q100 family of octal latches. It shares functional architecture with the 74HC373-Q100 but utilizes HCT logic for TTL input compatibility. The PW suffix denotes the TSSOP20 surface-mount package, distinguishing it from SO or DHVQFN variants within the same product line.

Latches Replacement Considerations

Direct substitutes include other AEC-Q100 qualified octal latches with identical pinouts and HCT logic levels. Verify equivalent propagation delays and output drive capabilities before substitution.
