SN74LS259BNSR

Latches Overview

The SN74LS259BNSR is an octal addressable latch from the Texas Instruments LS logic family, housed in a 16-pin SOIC package. It features serial input and parallel output capabilities with non-inverting polarity. The device operates within a supply voltage range of 4.75 V to 5.25 V. Propagation delay is specified at 30 ns at 5 V. It supports a minimum operating temperature of 0°C and a maximum of 70°C.

Latches Feature Summary

• Provides eight individually addressable latches for data storage
• Converts serial input data into parallel outputs
• Utilizes standard LS logic family characteristics

Latches Applications

• Digital display systems requiring addressable data storage
• Memory expansion circuits in microprocessor-based systems
• Data buffering applications in industrial control interfaces

Latches Procurement Notes

Verify the specific suffix BNSR confirms the surface-mount SOIC-16 package variant. Confirm the LS logic series designation matches system requirements, as HC or HCT variants offer different electrical characteristics. Ensure the operating temperature range of 0°C to 70°C aligns with the intended environmental conditions. Cross-reference the manufacturer part number against official datasheets to confirm pinout compatibility.

Latches Selection Notes

Select this component when a serial-to-parallel conversion function with individual addressability is required in a standard 5V logic environment. The LS family offers robust noise immunity suitable for general-purpose digital applications. Consider the SOIC-16 package for surface-mount assembly constraints. Evaluate propagation delay specifications against system timing requirements to ensure signal integrity.

Latches Part Context

This component belongs to the Texas Instruments SN74LS259 series of octal addressable latches. It is designed for use in digital logic circuits where data needs to be stored and accessed individually via address lines. The LS series represents a legacy standard in bipolar logic technology, widely used in established electronic designs.

Latches Replacement Considerations

SN74LS259BN is a direct PDIP-16 equivalent. SN74HC259N is a high-speed CMOS alternative with similar functionality but different voltage and speed characteristics.
