General Purpose CMOS Logic IC
Single 2-Input AND Gate
BU4S81G2
General Description
The BU4S81G2 is a 2-input single AND gate with buffered
output. Buffered output improves the characteristics of
propagation delay from gate input to output. Also, buffered
output suppress the fluctuating delay time which caused
by output 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.
