74HC259D-Q100,118

Latches Overview

The Nexperia 74HC259D-Q100,118 is an 8-bit addressable latch in a SO-16 package. It operates with a supply voltage range of 2.0 V to 6.0 V and supports temperatures from -40 °C to +125 °C. The device features four modes: addressable latch, memory, demultiplexer, and reset. Inputs include clamp diodes for interfacing with voltages exceeding VCC. It complies with AEC-Q100 Grade 1 standards and JEDEC JESD7A specifications.

Latches Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1
• Wide supply voltage range from 2.0 V to 6.0 V
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
• Inputs include clamp diodes for high-voltage interfacing

Latches Applications

• Automotive electronic systems requiring qualified logic components
• Serial-to-parallel data conversion circuits
• 3-to-8 active HIGH decoding or demultiplexing applications
• Random addressable data entry systems

Latches Procurement Notes

Verify the specific ordering suffix matches the required package type, as multiple options exist. Confirm the temperature range aligns with system requirements, noting that this specific part number is specified for operation up to +125 °C. Ensure design margins respect the absolute maximum ratings for supply voltage and current to prevent permanent damage.

Latches Selection Notes

Select this component when automotive reliability is required alongside standard CMOS logic functionality. The HC series offers compatibility with standard CMOS levels. Consider the SO-16 package dimensions if board space is constrained. Verify that the operating voltage falls within the 2.0 V to 6.0 V range for optimal performance across all specified modes.

Latches Part Context

This part belongs to the Nexperia 74HC259-Q100 family of 8-bit addressable latches. It shares functional characteristics with the 74HCT259-Q100 variant but differs in input voltage levels, supporting CMOS rather than TTL inputs. The D suffix indicates the SO-16 plastic small outline package, distinguishing it from TSSOP or DHVQFN alternatives.

Latches Replacement Considerations

Direct substitutes include other manufacturers' 74HC259 devices in SO-16 packages. Cross-reference pinouts and electrical characteristics carefully. Automotive-grade equivalents must also meet AEC-Q100 Grade 1 standards to maintain system qualification integrity.
