Overview
The SN74ALS580BNSR is an octal D-type transparent latch manufactured by Texas Instruments, featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels. The device provides a low-level output current of 24 mA and a high-level output current of -2.6 mA. Designed for surface mount installation, it utilizes a 20-pin SOIC package. The component functions in temperatures from 0°C to +70°C with a propagation delay of 14 ns.
Feature Summary
- Octal D-type transparent latch architecture
- Three-state output capability
- TTL-compatible input levels
Applications
- Driving highly capacitive loads
- Driving relatively low-impedance loads
- General-purpose data storage in digital systems
Procurement Notes
Verify the specific suffix 'NSR' corresponds to the SOIC-20 package and reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the operating temperature range meets system requirements. Validate pinout compatibility during integration. Check for any recent product lifecycle notices or obsolescence warnings from the manufacturer.
Selection Notes
Select this component when octal latching with three-state outputs is required. It is suitable for applications involving high capacitive or low-impedance loads. Consider the ALS logic family characteristics for speed and power consumption. Verify package availability and lead times against project schedules. Compare performance metrics with alternative logic families if necessary.
Part Context
This part belongs to the SN74ALS580B series of octal D-type transparent latches. It is part of the broader Texas Instruments logic IC portfolio. The device shares functional similarities with other octal latches but offers specific electrical characteristics. It is designed for standard digital logic applications requiring reliable data storage and bus isolation capabilities.
Replacement Considerations
Check for direct substitutes within the SN74ALS580B series. Verify pin-to-pin compatibility with other octal latch variants. Ensure logical function and electrical parameters match application requirements before substitution.
