Description

These devices contain four independent 2-input-NAND gates. The open-collector outputs require pull-up resistors to perform correctly. They 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 higher VOHlevels. The SN5403, SN54LS03 and SN54S03 are characterized for operation over the full military temperature range of -55°C to 125°C. The SN7403, SN74LS03 and SN74S03 are characterized for operation from 0°C to 70°C. These devices contain four independent 2-input-NAND gates.
