74HC259BZX

Latches Overview

The Nexperia 74HC259BZX is an 8-bit addressable latch housed in a DHXQFN16 (SOT8016-1) leadless package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports CMOS input levels. The device features four modes: addressable latch, memory, demultiplexer, and reset. It includes clamp diodes on inputs for overvoltage interfacing and provides ESD protection exceeding 2000 V (HBM). Operating temperatures span from -40 °C to +125 °C.

Latches Feature Summary

• Supports random data entry into specific storage bits via address inputs
• Functions as a combined demultiplexer and serial-to-parallel converter
• Includes common reset input to force all outputs LOW

Latches Applications

• Memory expansion systems requiring individual bit addressing
• Demultiplexing applications converting single input to multiple outputs
• Serial-to-parallel data conversion circuits

Latches Procurement Notes

Verify the exact suffix 'ZX' against official Nexperia documentation to confirm the DHXQFN16 package designation. Ensure compatibility with the specified 2.0 V to 6.0 V operating range and temperature specifications for your design environment.

Latches Selection Notes

Select this component when space-constrained designs require an 8-bit latch with individual output control. The DHXQFN16 package offers a compact footprint suitable for high-density PCB layouts. Verify that the CMOS input logic levels align with the driving circuit's output voltage characteristics.

Latches Part Context

This part belongs to the 74HC series of logic integrated circuits manufactured by Nexperia. It is functionally compatible with other 8-bit addressable latches in the industry standard family but utilizes a specific leadless thermal enhanced quad flat package variant.

Latches Replacement Considerations

Check datasheet Table 3 for equivalent packages such as 74HC259D (SO16), 74HC259PW (TSSOP16), or 74HC259BQ (DHVQFN16). Confirm pinout compatibility before substituting.
