Overview
The SN74AS32NSR is a quadruple 2-input positive-OR gate from the Texas Instruments AS logic series, housed in a 14-pin Small Outline Package (SOP). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device provides a low-level output current of 20 mA and a high-level output current of -2 mA. Switching characteristics include a maximum propagation delay of 5.8 ns at 5.5 V with a 50 pF load.
Feature Summary
- Contains four independent 2-input positive-OR gates performing Boolean functions Y = A + B
- Features high-speed switching capabilities characteristic of the AS logic family
- Provides robust drive capability with a low-level output current of 20 mA
Applications
- Boolean logic implementation in digital circuits
- Signal routing and selection networks
- Data bus management systems
Procurement Notes
Verify that the ordering suffix 'SR' corresponds to the SOP package and tape-and-reel packaging configuration as specified in the manufacturer's documentation. Confirm RoHS compliance status and lead finish details via the official package option addendum before procurement to ensure alignment with assembly requirements.
Selection Notes
Select this component when high-speed OR logic functionality is required alongside strong output drive capabilities. The AS series offers superior speed compared to ALS variants while maintaining standard TTL-compatible input thresholds. Ensure the design accommodates the higher power consumption inherent to the AS logic family relative to lower-power alternatives.
Part Context
This part belongs to the SN74AS32 family of quadruple 2-input positive-OR gates manufactured by Texas Instruments. It is designed for general-purpose digital applications requiring fast switching speeds. The device is available in multiple package options including plastic DIP and ceramic carriers, with the NSR variant specifically designated for surface-mount reflow soldering processes.
