What is SN74AS1000AN used for?
The SN74AS1000AN is used as a high-current NAND buffer driver in TTL bus systems, address decoders, and signal fan-out circuits where standard logic devices cannot deliver sufficient drive current. It is common in legacy industrial controllers, backplane bus drivers, and digital test equipment requiring Schottky-speed NAND gating with high output current to drive multiple load inputs.

Frequently Asked Questions
What is the output current capability of the SN74AS1000AN?
The SN74AS1000AN provides both IOH = 48 mA and IOL = 48 mA output drive capability. This high symmetric drive current allows it to source or sink significantly more current than standard TTL or CMOS logic gates, making it suitable for driving bus lines, LEDs, relay coils, and multiple receiver inputs in backplane and fan-out designs.
What logic family is the SN74AS1000AN part of?
It belongs to the AS (Advanced Schottky) TTL family, which uses Schottky-clamped transistors to prevent saturation and achieve very fast switching speeds. AS logic is faster than LS TTL and consumes moderate power, making it suitable for high-performance bus driving applications where propagation delay must be minimized.
How many NAND gates does the SN74AS1000AN contain?
The device integrates four independent 2-input positive NAND gates in a single 14-pin DIP package. Each gate operates fully independently, and all are rated for the same 48 mA drive current, allowing the designer to use any combination of gates as buffers, inverters (by tying inputs together), or logic NAND functions.
Is the SN74AS1000AN available in surface-mount packages?
The SN74AS1000AN is in a 14-pin DIP (dual-in-line plastic) package (JESD-30 code R-PDIP-T14), which is a through-hole format. For surface-mount assembly, designers should look for the SOIC or TSSOP variant in the SN74AS1000 family, such as the SN74AS1000AD or similar part numbers with SMD package designations.
