74LV573DB,112

Latches Overview

The 74LV573DB,112 is an octal D-type transparent latch manufactured by NXP Semiconductors. It features eight D-type inputs and three-state true outputs suitable for bus-oriented applications. The device operates within a supply voltage range of 1.0 V to 5.5 V and accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V. It utilizes a 20-lead SSOP plastic shrink small outline package (SOT339-1). The component supports ambient temperatures from -40 °C to +125 °C.

Latches Feature Summary

• Wide operating voltage range supporting low-voltage applications down to 1.0 V
• Inputs and outputs positioned on opposite sides of the package for easy microprocessor interfacing
• High electrostatic discharge protection exceeding 2000 V via Human Body Model standard

Latches Applications

• Bus-oriented data storage applications
• Microprocessor input or output port interfaces
• Low-voltage logic systems requiring wide supply compatibility

Latches Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and temperature range specifications. Confirm RoHS compliance status and REACH SVHC declarations with the supplier prior to procurement. Ensure the component source matches the authorized NXP distribution channels to guarantee authenticity and traceability.

Latches Selection Notes

Select this component when designing systems requiring an octal latch with three-state outputs in a compact surface-mount form factor. It serves as a pin-compatible alternative to 74HC573 and 74HCT573 devices while offering extended low-voltage operation capabilities. Consider the SSOP20 package dimensions for PCB layout constraints.

Latches Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices produced by NXP Semiconductors. The 74LV573 family provides octal latching functionality compatible with standard digital logic families. The DB variant specifically denotes the SSOP20 package configuration, distinguishing it from SO20 or DIP20 versions within the same logical family.

Latches Replacement Considerations

The 74LV573D,118 is a documented equivalent part number representing the same logical function in a similar package format. Verify pinout compatibility and electrical characteristics before substitution.
