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 VQH levels.

The SN5401 and SN54LSCQ1 are characterized

for operation over the full military temperature

range of —55°C to 125°C. The SN7401 and

SN74LS01 are characterized for operation from

0°C to 70°C.
