Overview
The SN74AS1000AN is a quad 2-input positive-NAND 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 high capacitive-drive capability with low-level output current up to 48 mA and high-level output current up to -48 mA. Propagation delay times are specified between 1 ns and 4 ns under standard test conditions.
Feature Summary
- Contains four independent 2-input positive-NAND buffers/drivers
- 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 signal buffering
- Line driving applications requiring high current drive
- General-purpose logic gate implementations
Procurement Notes
Verify that the ordering suffix 'AN' corresponds specifically to the plastic DIP-14 package configuration. Confirm RoHS compliance status as indicated in the manufacturer's packaging data. Ensure the component meets the required catalog specifications rather than military variants.
Selection Notes
Select this component when high-speed NAND logic is required alongside significant output drive strength. The AS series offers faster propagation delays compared to standard TTL families while maintaining robust current sourcing and sinking capabilities suitable for direct interface with heavy loads.
Part Context
This part belongs to the Texas Instruments SN74AS1000A family, which includes various package options such as SOIC (D), LCCC (FK), and ceramic DIP (J). The SN74AS1000A represents the commercial grade version characterized for operation from 0°C to 70°C, distinct from the SN54AS1000A military grade variant.
