74LV573DB,118

Latches Overview

The 74LV573DB,118 is a low-voltage Si-gate CMOS octal D-type transparent latch with 3-state outputs. It operates within a supply voltage range of 1.0 V to 5.5 V and features separate D-type inputs for each latch. The device includes common Latch Enable (LE) and Output Enable (OE) inputs. It is housed in a 20-lead SSOP package (SOT339-1) and supports an operating temperature range from -40 °C to +125 °C.

Latches Feature Summary

• Wide operating voltage range supporting applications from 1.0 V to 5.5 V
• Inputs accept TTL levels between VCC = 2.7 V and VCC = 3.6 V
• ESD protection exceeds 2000 V per HBM and 200 V per MM standards
• Inputs and outputs positioned on opposite sides of the package for microprocessor interfacing

Latches Applications

• Bus-oriented applications requiring 3-state true outputs
• Input or output port interfaces for microprocessors
• Low voltage logic systems compatible with 74HC573 and 74HCT573 pinouts

Latches Procurement Notes

Verify current product status as manufacturing availability may vary. Confirm package variant matches design requirements, specifically the SSOP20 form factor. Ensure environmental compliance aligns with project specifications. Review latest datasheet revisions for any functional updates before finalizing procurement.

Latches Selection Notes

Select this component for designs requiring wide voltage compatibility and high ESD robustness. It serves as a direct pin-compatible alternative to HC and HCT variants. Consider the specific propagation delay characteristics relative to the target supply voltage when designing timing-critical bus structures.

Latches Part Context

This device belongs to the NXP 74LV series of low-voltage CMOS logic components. It provides octal latching functionality with 3-state outputs. The part is functionally identical to the 74LV373 but utilizes a different pin arrangement. It is designed for general-purpose digital logic applications requiring transparent latching capabilities.

Latches Replacement Considerations

The 74LV373 offers equivalent logical functionality but differs in pin configuration. Other 74LV-series latches may provide similar performance metrics. Verify pinout compatibility and electrical specifications against existing circuit designs before substituting.
