74LV259DB,118

Latches Overview

The 74LV259DB,118 is an 8-bit addressable latch manufactured by NXP USA Inc. in a 16-lead SSOP package (SOT338-1). It operates within a supply voltage range of 1.0 V to 3.6 V and supports ambient temperatures from -40 °C to +125 °C. The device provides four operational modes: addressable latch, memory, demultiplexer, and reset. It features active HIGH outputs, an active LOW common reset (MR), and an active LOW latch enable (LE). Propagation delays vary with voltage, ranging from 14 ns to 105 ns depending on the input path and load conditions.

Latches Feature Summary

• Combines serial-to-parallel conversion with random addressable data entry capabilities
• Functions as an 8-channel demultiplexer or 3-to-8 decoder with active HIGH outputs
• Includes an active LOW common reset for immediate clearing of all latches
• Offers robust electrostatic discharge protection exceeding specified industry standards

Latches Applications

• General purpose digital storage applications requiring addressable data retention
• Serial-to-parallel data conversion systems
• Decoder and demultiplexing circuits in digital logic designs

Latches Procurement Notes

Verify that the specific ordering suffix matches the required SSOP16 package variant. Confirm the temperature grade aligns with system requirements, as extended ranges are available. Ensure compatibility with existing PCB footprints for the SOT338-1 outline. Cross-reference the manufacturer part number against current product status to confirm availability and lead times before finalizing procurement plans.

Latches Selection Notes

Select this component when low-voltage operation between 1.0 V and 3.6 V is required alongside TTL level acceptance at higher voltages. Consider the SSOP16 package if space-constrained surface-mount assembly is necessary. Evaluate propagation delay specifications against system timing constraints, noting variations across different supply voltages and load capacitances.

Latches Part Context

This device belongs to the 74LV series of low-voltage CMOS logic components. It maintains pin and functional compatibility with 74HC259 and 74HCT259 devices, facilitating direct upgrades or replacements in existing designs. The family focuses on optimizing performance for modern low-power digital systems while retaining standard interface characteristics.

Latches Replacement Considerations

Compatible substitutes include the 74LV259D (SO16 package) and 74LV259PW (TSSOP16 package). Verify package dimensions and thermal characteristics when transitioning between SSOP, SO, and TSSOP variants to ensure mechanical fit.
