TECHNICAL DATA IW4020B 14 Stage Ripple-Carry Binary Counter/Divider High-Voltage Silicon-Gate CMOS The IW4020B is ripple-carry binary counter. All counter stages are masterslave flip-flops. The state of a counter advances one count on the negative transition of each input pulse; a high level on the RESET line resets the counter to its all zeros state. Schm.
