Ceramic (J) 300-mil DIPs
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.
