General Purpose CMOS Logic IC
Single 2-Input NOR Gate
BU4S01G2
General Description
The BU4S01G2 is a 2-input NOR gate.
An inverter-based buffer is incorporated at the gate output
to improve I/O transmission characteristics, and it
minimizes a variation in the propagation delay time
caused by an increase in the load capacitance.

Caution:
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.
