74HC259PW-Q100,118

Latches Overview

The Nexperia 74HC259PW-Q100,118 is an 8-bit addressable latch in a TSSOP16 package (SOT403-1). It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features four modes: addressable latch, memory, demultiplexer/decoder, and reset. It complies with AEC-Q100 Grade 1 standards for automotive applications. Static characteristics include input leakage current up to ±1 μA at 6.0 V and supply current up to 160 μA. Dynamic propagation delay from D to Qn ranges from 17 ns to 56 ns depending on voltage and temperature.

Latches Feature Summary

• Automotive qualification according to AEC-Q100 Grade 1 standard
• Four operational modes including addressable latch, memory, demultiplexer, and reset
• Wide supply voltage range supporting 2.0 V to 6.0 V operation
• High ESD protection exceeding 2000 V HBM and 1000 V CDM

Latches Applications

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

Latches Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74HC259 family includes SO16 and DHVQFN variants. Confirm that the HC logic level inputs are compatible with the system's CMOS voltage levels rather than TTL requirements. Ensure design safeguards account for the specified operating temperature range and power dissipation derating curves provided in the datasheet.

Latches Selection Notes

Select this component when an 8-bit addressable latch with automotive reliability is required. The HC series offers CMOS input levels suitable for general digital interfaces. Consider the TSSOP16 package dimensions if space constraints favor thin shrink small outline packages over standard SO or QFN formats. Verify that the system voltage falls within the 2.0 V to 6.0 V range for optimal performance.

Latches Part Context

This part belongs to the Nexperia 74HC259-Q100 family, which also includes the 74HCT259-Q100 variant featuring TTL-compatible input levels. The family provides identical functional behavior but differs in input threshold voltages. Other package options within the same logical family include the SO16 (SOT109-1) and DHVQFN16 (SOT763-1) configurations, allowing flexibility in board layout and thermal management strategies.

Latches Replacement Considerations

The 74HC259D-Q100,118 serves as a direct functional substitute using the SO16 package instead of TSSOP16. Designers must verify pinout compatibility and physical footprint differences between SOT403-1 and SOT109-1 packages before substitution.
