74LVC573ABQ,115

Latches Overview

The Nexperia 74LVC573ABQ,115 is an octal D-type transparent latch with 3-state outputs and 5 V tolerant inputs/outputs. It operates within a supply voltage range of 1.2 V to 3.6 V. The device features latch enable (LE) and output enable (OE) inputs. Propagation delay from Dn to Qn is 3.4 ns at 3.3 V. Static current is 40 uA. High-level output current is -24 mA. Operating temperature ranges from -40 °C to +125 °C. Package is DHVQFN-20.

Latches Feature Summary

• Octal D-type transparent latch with 3-state outputs
• 5 V tolerant inputs and outputs for mixed voltage environments
• IOFF circuitry provides partial power-down mode operation
• Schmitt-trigger action on all inputs

Latches Applications

• Bus-oriented applications requiring 3-state non-inverting outputs
• Input or output port for microprocessors and microcomputers
• Translators in mixed 3.3 V and 5 V environments

Latches Procurement Notes

Verify the specific ordering suffix ABQ corresponds to the DHVQFN20 package (SOT764-1). Confirm the temperature range is specified as -40 °C to +125 °C for this variant. Ensure compliance with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 is required for the target operating voltage. Check for any recent Product Change Notifications affecting pinout or marking.

Latches Selection Notes

Select this component when an octal latch with 5 V tolerance is needed alongside low-voltage logic families. The DHVQFN20 package offers a compact footprint suitable for space-constrained designs. Verify that the input transition rates comply with recommended operating conditions for the chosen supply voltage to ensure signal integrity.

Latches Part Context

This part belongs to the 74LVC573A family of octal D-type transparent latches. It shares functional similarities with other LVC series devices but is distinguished by its 5 V tolerance and specific package configuration. The ABQ suffix denotes the DHVQFN20 thermal enhanced very thin quad flat package without leads.

Latches Replacement Considerations

Direct replacements include 74LVC573AD,118 (SO20 package) and 74LVC573APW,118 (TSSOP20 package). These variants maintain identical electrical characteristics and pinouts but differ in physical package dimensions.
