Overview
The SN74AS1000ANS is a Texas Instruments logic gate containing four independent 2-input positive-NAND buffers/drivers. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from 0°C to 70°C. The device features a propagation delay of 1 ns to 4 ns at 50 pF load, with high-level output current capability up to -48 mA and low-level output current up to 48 mA. It is housed in a 14-pin SOP (NS) package.
Feature Summary
- Contains four independent 2-input positive-NAND buffer/driver circuits
- Provides high capacitive-drive capability for demanding loads
- Supports Boolean functions Y = A • B or Y = A + B in positive logic
Applications
- High-speed digital logic buffering
- Capacitive load driving applications
- Positive logic circuit implementation
Procurement Notes
Verify the exact ordering suffix 'ANSR' against the official Package Option Addendum to confirm the SOP (NS) package type and tape-and-reel quantity specifications. Ensure that the selected variant matches the required RoHS compliance status and moisture sensitivity level ratings documented by the manufacturer.
Selection Notes
Select this component when four independent NAND gates with high drive strength are required. The AS series offers faster switching speeds compared to standard TTL. Verify that the application environment remains within the specified 0°C to 70°C operating temperature range and utilizes a 5V nominal power supply.
Part Context
This part belongs to the Texas Instruments 74AS (Advanced Schottky) logic family, known for high speed and reduced power dissipation relative to standard TTL. The SN74AS1000A specifically provides quad 2-input NAND functionality. It serves as the commercial-grade counterpart to the military-specification SN54AS1000A, sharing identical electrical characteristics but differing in temperature ranges.

FAQ
What is the maximum propagation delay for the SN74AS1000ANS?
The maximum propagation delay is 4 ns when tested with a 50 pF load capacitance.
Does the SN74AS1000ANS support open-collector outputs?
No, the datasheet specifies it contains positive-NAND buffers/drivers with standard totem-pole outputs, not open-collector configurations.
