TC74HC4520AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC4520AP, TC74HC4520AF Dual 4-Bit Binary Counter The TC74HC4520A is high speed CMOS DUAL BCD/4-BIT BINARY COUNTER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Since it contains two independent counter circuits in one package, counting or frequency division of eight binary bits can be achieved with one device. The counter is reset to “O” (Q0 to Q3 low) by setting the CLR input high regardless of the other inputs. Counting occurs on the positive going (rising edge) transition of CK if CE is high or...
