TC4538BP/BF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC4538BP, TC4538BF TC4538BP/TC4538BF Dual Precision Retriggerable/Resettable Monostable Multivibrator The TC4538BP/BF is the retriggerable/resettable monostable TC4538BP multivibrator and the trigger operation can be made at either the leading or trailing edge by 2 inputs of A and B. Since the output monostable pulse width is decided by time constant of the external resistor (R ) and the external capacitor (C ), it becomes possible to X X set a broad range of output pulse widths. Features t = 10 ms 5% (at R = 100 k C = 0.1 F, V = 10 V) wOUT X X DD TC4538BF Pin Assignment Weight DIP16-P-300-2.54A : 1.00 g (typ.) SOP16-P-300-1.27A : 0.18 g (typ.)
