description
These devices contain four independent 2-input
positive-NAND buffers. They perform the Boolean
functions Y = A
• B or Y = A + B in positive logic.
The open-collector outputs require pullup
resistors to perform correctly . These outputs may
be connected to other open-collector outputs to
implement active-low wired-OR or active-high
wired-AND functions. Open-collector devices are
often used to generate high V
OH
levels.
The SN54ALS03B is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74ALS03B is characterized for
operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
