Overview
The SN74AS32NS is a Texas Instruments integrated circuit belonging to the 74AS logic series. It contains four independent 2-input positive-OR gates housed in a 14-pin SOIC surface-mount package. The device operates within a supply voltage range of 4.5V to 5.5V and supports a low-level output current of 20mA and a high-level output current of 2mA. Maximum propagation delay is specified at 5.8ns under conditions of 5V supply and 50pF load capacitance. Operating temperature ranges from 0°C to 70°C.
Feature Summary
- Contains four independent 2-input OR logic functions
- Provides high-speed switching performance characteristic of the AS series
- Features push-pull outputs for robust signal driving
Applications
- Digital logic signal processing
- Data routing circuits
- Control logic interfaces
Procurement Notes
Verify the specific suffix 'NS' against official manufacturer documentation to confirm pinout, package dimensions, and electrical characteristics match project requirements. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments, as availability may vary by region.
Selection Notes
Select this component when high-speed OR gate functionality is required in a surface-mount design. Compare propagation delay and drive strength against other 74-series families such as ALS or LS to ensure compatibility with system timing constraints and load requirements.
Part Context
This part belongs to the Texas Instruments 74AS (Advanced Schottky) family, known for improved speed over standard TTL. The SN74AS32 variant specifically provides OR logic. The NS suffix denotes the 14-lead Small Outline Integrated Circuit (SOIC) package type suitable for automated surface-mount assembly processes.
Replacement Considerations
Consult official substitution guides for equivalent parts within the 74AS family or compatible alternatives from other manufacturers. Verify pin-to-pin compatibility and electrical parameter alignment before implementation.
