Overview
The SN74ALS580BNS is an octal D-type transparent latch manufactured by Texas Instruments within the ALS logic series. It features eight independent latches with inverting outputs, housed in a 20-pin SOIC package. The device operates on a supply voltage ranging from 4.5 V to 5.5 V and supports a propagation delay of 18 ns. It provides a low-level output current of 32 mA and a high-level output current of -2.6 mA. The component functions reliably across an operating temperature range of 0°C to +70°C.
Feature Summary
- Octal configuration providing eight independent transparent latch circuits for parallel data storage
- Inverting output polarity characteristic inherent to the specific logic family implementation
- High drive capability enabled by advanced low-power Schottky bipolar technology
Applications
- Parallel-to-serial data conversion interfaces
- Temporary data buffering in digital processing systems
- Address register storage in microprocessor-based architectures
Procurement Notes
Verify the exact suffix against manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure the ordering part number matches the required industrial or commercial temperature grade. Confirm RoHS compliance status through official datasheets prior to procurement.
Selection Notes
Select this component when designing systems requiring multiple simultaneous data latching operations with inverting logic. Consider the 20-pin SOIC footprint for surface-mount assembly constraints. Evaluate the 18 ns propagation delay against system timing requirements to ensure signal integrity.
Part Context
This part belongs to the Texas Instruments SN74ALS580B series, representing octal latches utilizing Advanced Low-Power Schottky technology. The series is designed for high-speed digital applications requiring reduced power consumption compared to standard TTL while maintaining compatible interface levels.
Replacement Considerations
Consult official substitution guides for equivalent octal latches within the ALS family. Verify pinout compatibility and electrical characteristics before replacing.
