MC14020B 14-Bit Binary Counter
The MC14020B 14–stage binary counter is constructed with MOS P–channel and N–channel enhancement mode devices in a single monolithic structure. This part is designed with an input wave shaping circuit and 14 stages of ripple–carry binary counter. The device advances the count on the negative–going edge of the clock pulse. Applications include time delay circuits, counter controls, and frequency–dividing circuits. Fully Static Operation Diode Protection on All Inputs Supply Voltage Range = 3.0 Vdc to 18 Vdc Capable of Driving Two Low–power TTL Loads or One Low–power Schottky TTL Load Over the Rated Temperature Range Buffered Outputs Available from stages 1 and 4 thru 14 Common Reset Line Pin–for–Pin Replacement for CD4020B MAXIMUM RATINGS* (Voltages Referenced to VSS)
