Overview
The SN74AS1008ANS is a quadruple 2-input positive-AND buffer/driver from the Texas Instruments AS logic series. 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 features four independent gates with a propagation delay of 6 ns at 50 pF load. It provides high sink/source output currents of 48 mA, enabling significant capacitive-drive capability.
Feature Summary
- Contains four independent 2-input positive-AND buffers/drivers performing Boolean functions Y = A • B or Y = A + B in positive logic.
- Offers high capacitive-drive capability suitable for demanding bus driving applications.
Applications
- High-speed digital logic circuits requiring fast switching times
- Bus driver applications utilizing strong drive capabilities
- General-purpose logic buffering in industrial environments
Procurement Notes
Verify that the specific part number matches the required package type, as the 'N' suffix indicates a Plastic DIP (PDIP) package while other suffixes denote SOIC packages. Confirm RoHS compliance status and lead finish details against the latest Package Option Addendum before finalizing procurement specifications.
Selection Notes
Select this component when high-speed AND gate functionality combined with substantial current drive is necessary. The AS series offers faster propagation delays compared to standard TTL but consumes more power. Ensure the application environment remains within the specified 0°C to 70°C operating temperature range for reliable performance.
Part Context
This device belongs to the Texas Instruments SN74AS1008A family, which represents the Advanced Schottky (AS) logic series. This series is characterized by high speed and high fan-out capabilities, making it suitable for complex digital systems where signal integrity and rapid processing are critical requirements.
