SN74LS259BNSRG4

Latches Overview

The SN74LS259BNSRG4 is a single addressable latch from the Texas Instruments LS series, housed in a 16-pin SOIC package. It features D-type logic with standard outputs and operates on a single independent circuit. The device supports a supply voltage range of 4.75V to 5.25V. Key electrical characteristics include a low-level output current of 32mA and a propagation delay of approximately 19ns at 5V. The component is lead-free compliant but contains lead, with a maximum operating temperature of 70°C.

Latches Feature Summary

• Single-channel addressable latch functionality
• D-type logic configuration with standard outputs
• High drive capability with 32mA low-level output current

Latches Applications

• Digital data storage systems
• Address decoding circuits
• Memory buffer applications

Latches Procurement Notes

Verify the specific suffix 'SRG4' indicates tape and reel packaging and RoHS compliance status. Confirm lead-free status details as documentation may contain conflicting lead information. Ensure the 16-SOIC package matches the design footprint requirements. Check for obsolete status indicators before finalizing procurement plans.

Latches Selection Notes

Select this component when an addressable latch with high sink current is required. The LS series offers specific speed and power trade-offs compared to HC or HCT variants. Verify that the 5V supply voltage aligns with the system architecture. Consider the SOIC package size constraints during PCB layout planning.

Latches Part Context

This part belongs to the Texas Instruments SN74LS259 family of addressable latches. It serves as a digital memory element where individual outputs can be set independently based on address inputs. The LS technology provides moderate speed performance suitable for general-purpose digital logic applications requiring reliable data retention.

Latches Replacement Considerations

The SN74HC259N is a compatible alternative offering similar functionality with different electrical characteristics. Verify voltage compatibility and package pinout alignment before substitution. Note that HC series parts may have different propagation delays and drive strengths compared to the LS variant.
