Datasheet General Purpose CMOS Logic IC Single 2-Input OR Gate BU4S71G2 General Description Key Specifications The BU4S71G2 is a 2-input single OR gate with buffered Supply Voltage Range: +3V to +16V output. Buffered output improves the characteristics of Input Voltage Range: V to V SS DD propagation delay from gate input to output. Also, buffered Operating Temperature Range: -40C to +85C output suppress the fluctuating delay time which caused by output load capacitance.

A 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.
