SN74LS259BDR

Latches Overview

The SN74LS259BDR is an 8-bit addressable latch from the Texas Instruments SN74LS series, housed in a 16-pin SOIC-Narrow package. It operates on a single supply voltage ranging from 4.75 V to 5.25 V. The device features a propagation delay of 21 ns and supports surface-mount installation. It functions within a temperature range of 0°C to +70°C.

Latches Feature Summary

• Provides eight individually addressable data latches for parallel output storage
• Utilizes D-type input architecture with dedicated address decoding inputs
• Offers non-inverting outputs for direct logic interfacing

Latches Applications

• Parallel data buffering in digital systems
• Address decoding circuits
• Memory interface modules

Latches Procurement Notes

Verify the specific suffix 'BDR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target assembly process. Cross-reference the active status and lead times directly with authorized distributors or Texas Instruments official channels prior to procurement.

Latches Selection Notes

Select this component when designing systems requiring multiple independent latched outputs controlled by a common clock and address lines. It is suitable for applications needing low power consumption typical of the LS logic family while maintaining compatibility with standard 5V logic levels. Consider pinout compatibility if replacing older variants.

Latches Part Context

This part belongs to the SN74LS family of high-speed低功耗 Schottky logic devices. It serves as a memory element within larger digital architectures, distinct from multiplexers like the SN74LS258. The SOIC-16 package facilitates automated surface-mount assembly, making it appropriate for modern PCB designs requiring compact footprints.

Latches Replacement Considerations

Check for SN74LS259N (PDIP) for through-hole alternatives. Verify SN74HC259 equivalents for CMOS performance upgrades, noting voltage and speed differences.
