74HC75D,653

Latches Overview

The Nexperia 74HC75D,653 is a quad bistable transparent latch housed in a 16-lead SO plastic small outline package (SOT109-1). It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features two active HIGH enable inputs (LE12 and LE34) controlling four latches with complementary outputs. Static characteristics include input leakage current up to ±1.0 μA at 6.0 V and supply current up to 80 μA. Dynamic propagation delay ranges from 19 ns to 32 ns depending on voltage and temperature.

Latches Feature Summary

• Quad bistable transparent latch architecture with complementary Q and nQ outputs
• Dual active HIGH enable inputs (LE12 and LE34) for simultaneous control of latch groups
• CMOS low power dissipation with high noise immunity
• ESD protection exceeding 2000 V per HBM and 1000 V per CDM standards

Latches Applications

• Data storage circuits requiring transparent latch functionality
• Parallel data acquisition systems
• Digital signal processing interfaces
• Microcontroller peripheral expansion

Latches Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the component meets JEDEC compliance standards relevant to the target application environment. Ensure design specifications align with the absolute maximum ratings provided in the datasheet to prevent permanent damage during operation or testing phases.

Latches Selection Notes

Select this component when a quad latch configuration with dual enable controls is required. The wide supply voltage range accommodates various logic families. Consider the SO16 package dimensions for PCB layout constraints. Verify that the operating temperature range meets the environmental requirements of the final assembly.

Latches Part Context

This part belongs to the 74HC series of CMOS logic devices manufactured by Nexperia. It is functionally equivalent to other quad latch variants within the standard logic family but offers specific pinout and packaging options. The 74HC75D variant specifically denotes the SO16 package configuration suitable for surface mount applications.

Latches Replacement Considerations

Check for direct cross-references from other manufacturers offering identical pinouts and electrical characteristics. Verify compatibility with existing board layouts and ensure that any substitute maintains the same ESD protection levels and operating voltage ranges.
