74LS93 - 4 Bit Ripple CountersThe 74LS93 is a high-speed
4-bit ripple type counters partitioned into two sections. Each counter has a divide-by-two
section divide-by-eight (LS93) section which are triggered by a HIGH-to-LOW transition
CD4017 - Decade CounterThe CD4017 is a 5-stage divide-by-10 Johnson
counter with 10 decoded outputs and a carry out bit. The counters are cleared to their zero count by a logical
‘‘1’’ on their reset line. These counters are advanced on the
CD4020 - 14Bit Binary CounterThe CD4020 is a ripple-carry binary counter. All counter stages are master-slave 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 ..
CD4022 - Octal Divider CounterThe CD4022 is a 4-stage divide-by-8 Johnson
counter with 8 decoded outputs and a carry-out bit.
These counters are cleared to their zero count by a logical
‘‘1’’ on their reset line. These counters are advanced on the..
CD4026 - Decade Counter-DividerCD4026 is a Johnson counter IC commonly used in digital display. It has a 5 stage Johnson decade counter with a decoder which converts the Johnson code to a 7 segment decoded output. To put it simply, it ..
CD4029 - Presettable Up-Down CounterThe CD4029BM/CD4029BC is a presettable up/down
counter which counts in either binary or decade mode depending
on the voltage level applied at binary/decade input.
When binary/decade is at logical ‘‘1’’, the coun..
CD4033 - Decade Counter-DividerCD4033 consists of a 5 stage Johnson decade counter
and an output decoder which converts the Johnson code to a 7
segment decoded output for driving one stage in a numerical
This device is particularly advan..
CD4040 - 12-Stage Ripple Carry Binary CountersThe CD4040 is a 12-stage ripple carry binary counter. The counters are advanced one count on the negative transition of each clock pulse. The counters are reset to the zero state by a logic..
CD4060 - Binary Counter-Divider & OscillatorCD4060 consists of an oscillator
section and 14 ripple-carry binary counter
stages. The oscillator configuration allows
design of either RC or crystal oscillator
circuits. A RESET input is provided ..
CD4518 - Dual BCD Up CounterCD4518 Dual BCD Up-Counter and CD4520 Dual Binary Up-Counter each consist of two identical, internally synchronous 4-stage counters. The counter stages are D-type flip-flops having interchangeable CLOCK and ENABLE lines fo..
