74HC75D,652

Latches Overview

The Nexperia 74HC75D,652 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 controlling four latches with complementary outputs. Static characteristics include input leakage current up to ±1.0 μA at maximum temperature and supply current up to 160 μA. Dynamic performance specifies propagation delays up to 38 ns at 4.5 V and transition times up to 22 ns.

Latches Feature Summary

• Quad bistable transparent latch architecture with complementary Q and nQ outputs
• Dual active HIGH latch enable inputs for simultaneous control of paired latches
• ESD protection compliant with ANSI/ESDA/JEDEC JS-001 class 2 and JS-002 class C3 standards
• CMOS low power dissipation with high noise immunity

Latches Applications

• Data storage circuits requiring parallel load and hold functionality
• Interface logic for buffering signals between different voltage domains
• Control logic systems utilizing transparent latch behavior for timing synchronization

Latches Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and temperature grade. Confirm RoHS compliance status and check for any product change notices or end-of-life announcements prior to finalizing design-in decisions. Ensure the selected variant matches the required lead count and body width specifications.

Latches Selection Notes

Select this component when a quad latch configuration with dual enable controls is required. The wide supply voltage range allows compatibility with various CMOS logic families. Verify that the operating temperature range meets the environmental requirements of the target application. Consider the package dimensions and thermal derating characteristics for PCB layout planning.

Latches Part Context

This part belongs to the Nexperia 74HC logic family, which utilizes CMOS technology for low power consumption and high noise immunity. The 74HC75 specifically provides transparent latch functionality, distinguishing it from edge-triggered flip-flops by allowing output changes during the enable pulse. It is designed for general-purpose digital applications requiring data retention and signal buffering.

Latches Replacement Considerations

Direct pin-compatible replacements may include other manufacturers' 74HC75 variants. Verify electrical parameters such as propagation delay and output drive capability to ensure functional equivalence. Check for differences in ESD protection levels and operating temperature ranges before substituting.
