74LV259PW,112

Latches Overview

The NXP USA Inc. 74LV259PW,112 is a low-voltage Si-gate CMOS device functioning as an 8-bit addressable latch. It operates within a supply voltage range of 1.0 V to 3.6 V and accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V. The component provides active HIGH outputs (Q0 to Q7) and incorporates an active LOW common reset (MR) alongside an active LOW enable input (LE). It supports four operational modes: addressable latch, memory, 3-to-8 decoding/demultiplexing, and reset. The device is housed in a TSSOP16 plastic thin shrink small outline package with a body width of 4.4 mm.

Latches Feature Summary

• Combines demultiplexer and 8-bit latch capabilities for serial-to-parallel conversion
• Supports random addressable data entry with individual storage bit output availability
• Includes ESD protection exceeding 2000 V per HBM standard and 200 V per MM standard
• Features a common reset input and is easily expandable for system integration

Latches Applications

• General purpose digital system storage applications
• Addressable latch configurations for data storage
• 3-to-8 decoder implementations
• Demultiplexer functions with active HIGH outputs

Latches Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP16 package variant when sourcing. Confirm RoHS compliance status and temperature range specifications (-40 °C to +125 °C) against project requirements. Ensure interface compatibility with existing logic families by checking input level tolerances at the target operating voltage.

Latches Selection Notes

Select this component for designs requiring low-voltage operation down to 1.0 V while maintaining compatibility with higher voltage logic interfaces. Consider its multifunctional nature for space-constrained layouts needing both latching and decoding. Evaluate power dissipation characteristics and thermal performance if operating near maximum ambient temperatures or utilizing multiple units simultaneously.

Latches Part Context

This device belongs to the 74LV series of low-voltage CMOS logic components manufactured by NXP Semiconductors. It serves as a pin and function compatible alternative to the 74HC259 and 74HCT259 devices, offering optimized performance for lower voltage digital systems. The PW suffix indicates the specific TSSOP16 packaging format used for surface-mount assembly.

Latches Replacement Considerations

The 74LV259 is pin and function compatible with the 74HC259 and 74HCT259. Verify voltage level compatibility before substituting these parts, as the LV series operates at lower supply voltages.
