74AHCT573PW-Q100J

Latches Overview

The Nexperia 74AHCT573PW-Q100J 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 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL input levels, overvoltage tolerant inputs up to 5.5 V, and Schmitt-trigger action on all inputs. It utilizes a TSSOP20 (SOT360-1) package with 20 leads.

Latches Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• TTL input levels compatible with standard logic families
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• Schmitt-trigger action on all inputs for improved noise immunity

Latches Applications

• Bus-oriented applications requiring 3-state non-inverting outputs
• Input or output ports for microprocessors and microcomputers
• Data latching in automotive electronic control units

Latches Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature grade. Confirm that the requested component matches the exact part number listed in the official datasheet to avoid functional discrepancies related to input logic levels or electrical characteristics.

Latches Selection Notes

Select this component when TTL-compatible inputs are required alongside wide supply voltage flexibility. The 3-state outputs facilitate bus sharing in complex digital systems. Ensure the design accommodates the specified operating temperature range and power dissipation limits for the TSSOP20 package under maximum load conditions.

Latches Part Context

This component belongs to the Nexperia 74AHC(AHCT)573-Q100 family of octal D-type transparent latches. It shares functional similarities with other members of the series but differs in input logic compatibility, specifically utilizing TTL thresholds for the AHCT variant compared to CMOS thresholds for the AHC variant.

Latches Replacement Considerations

Direct substitutes include the 74AHC573PW-Q100J for CMOS input levels or the 74AHCT573PW without the Q100 suffix for non-automotive grades. Verify pinout and electrical specifications match before substitution.

Latches FAQ

What is the difference between the 74AHC573-Q100 and 74AHCT573-Q100?

The primary difference is the input level; the 74AHC573-Q100 uses CMOS input levels, while the 74AHCT573-Q100 uses TTL input levels.

How does the OE input affect the latch state?

The Output Enable (OE) input controls the high-impedance OFF-state of the outputs but does not affect the internal state stored in the latches.
