TC4538BF

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 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 (RX) and the external capacitor (CX), it becomes possible to set a broad range of output pulse widths. Features twOUT = 10 ms ± 5% (at RX = 100 kΩ CX = 0.1 μF, VDD = 10 V) Pin Assignment TC4538BP TC4538BF Weight DIP16-P-300-2.54A SOP16-P-300-1.27A : 1.00 g (typ.) : 0.18 g (typ.)
