BU4538B ROHM

Datasheet General Purpose CMOS Logic IC Monostable Multivibrator BU4538B General Description Key Specifications The BU4538B is the retriggerable/resetable monostable Operating Supply Voltage Range: 3V to 16V multivibrator. The trigger operation can be made at either Input Voltage Range: V to V SS DD the rising or falling edge by 2 inputs of A and B. A wide Operating Temperature Range: -40C to +85C range of accurate output pulse width is available because the output pulse width and accuracy are Package W(Typ) x D(Typ) x H(Max) determined by the external timing constants Cx and Rx.
