74LV259DB,112

Latches Overview

The 74LV259DB,112 is an 8-bit addressable latch manufactured by NXP USA Inc. in a 16-lead SSOP package. It operates within a supply voltage range of 1.0 V to 3.6 V and accepts TTL input levels between 2.7 V and 3.6 V. The device integrates eight addressable latches with active HIGH outputs (Q0 to Q7), functioning as a demultiplexer or decoder. It features an active LOW common reset (MR) and an active LOW latch enable (LE). Static characteristics specify maximum input leakage current at 1.0 µA and supply current up to 160 µA. Dynamic performance includes propagation delays ranging from 14 ns to 61 ns depending on voltage and temperature.

Latches Feature Summary

• Combines serial-to-parallel conversion with random addressable data entry capabilities
• Functions as an 8-channel demultiplexer or active HIGH decoder
• Includes a common reset input for simultaneous clearing of all latches

Latches Applications

• General purpose storage applications in digital systems
• Serial-to-parallel data conversion circuits
• Address decoding and demultiplexing logic

Latches Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm RoHS compliance status and lead-free specifications against the latest manufacturer documentation. Ensure the ambient operating temperature range aligns with system requirements before finalizing procurement orders.

Latches Selection Notes

Select this component when pin and function compatibility with 74HC/HCT259 devices is required alongside low-voltage operation. Evaluate the specific package dimensions and thermal dissipation limits relative to the target PCB layout constraints. Consider the input voltage thresholds if interfacing with legacy logic families.

Latches Part Context

This device belongs to the 74LV series of low-voltage Si-gate CMOS logic components. It serves as a multifunctional storage element capable of addressing individual bits within an octet. The design supports expansion into larger memory structures through its addressable architecture.

Latches Replacement Considerations

Pin-compatible alternatives include the 74HC259 and 74HCT259 variants. Verify that the substitute part meets the specific low-voltage operational requirements of the original application.
