74HCT259PW,118

Latches Overview

The Nexperia 74HCT259PW,118 is an 8-bit addressable latch in the HCT logic series, housed in a TSSOP-16 package (SOT403-1). It operates on a supply voltage range of 4.5 V to 5.5 V with an operating temperature range of -40 °C to +125 °C. The device features TTL-compatible input levels and includes clamp diodes for overvoltage interfacing. Key dynamic characteristics at VCC = 4.5 V include propagation delays up to 59 ns and set-up times up to 26 ns.

Latches Feature Summary

• Combines demultiplexer and 8-bit latch functionality
• TTL-compatible input levels
• Serial-to-parallel capability
• Common reset input

Latches Applications

• Addressable data storage
• Demultiplexing applications
• Decoder circuits

Latches Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the HCT logic family aligns with system voltage requirements. Ensure thermal management accounts for power dissipation limits within the specified ambient temperature range. Cross-reference the datasheet revision date against current manufacturing standards.

Latches Selection Notes

Select this component when TTL-level inputs are required alongside addressable latching capabilities. The HCT series ensures compatibility with standard logic families while providing robust performance across wide temperature ranges. Consider the TSSOP-16 package for surface-mount assembly constraints and pin count requirements.

Latches Part Context

This part belongs to the 74HC/HCT259 family of 8-bit addressable latches. It shares functional similarities with other variants like the 74HC259 but differs in input threshold specifications. The PW suffix indicates the TSSOP-16 plastic thin shrink small outline package configuration.

Latches Replacement Considerations

Direct substitutes include the 74HC259PW,118 for CMOS-level input compatibility.
