74HC259PW,118

Latches Overview

The Nexperia 74HC259PW,118 is an 8-bit addressable latch in a TSSOP16 package. It operates on a supply voltage of 2.0 V to 6.0 V and supports temperatures from -40 °C to +125 °C. Propagation delay ranges from 16 ns to 56 ns depending on voltage. Inputs include clamp diodes for overvoltage interfacing.

Latches Feature Summary

• Supports four modes: addressable latch, memory, demultiplexer, and reset.
• Features serial-to-parallel capability with random data entry.
• Includes input clamp diodes for interfacing voltages exceeding VCC.

Latches Applications

• Serial-to-parallel conversion
• 3-to-8 active HIGH decoding
• Addressable data storage

Latches Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm RoHS compliance status and AEC-Q100 qualification requirements against project specifications before finalizing procurement orders.

Latches Selection Notes

Select this component for designs requiring individual bit addressing within an 8-bit array. Ensure the logic family (HC vs HCT) aligns with system voltage levels and interface requirements.

Latches Part Context

This device belongs to the 74HC series of high-speed CMOS logic. It provides flexible configuration as a latch or decoder. The PW suffix indicates the TSSOP16 plastic thin shrink small outline package.

Latches Replacement Considerations

Check for direct equivalents such as the 74HC259D in SO16 packaging if pin compatibility allows. Verify functional parity across all operating modes before substitution.

Latches FAQ

How does the device handle inputs exceeding VCC?

Inputs include clamp diodes, allowing current limiting resistors to be used for interfacing to voltages greater than VCC.

What determines the output state in demultiplexer mode?

In demultiplexer mode, the addressed output follows the D input while all other outputs are forced LOW.
