CD4017B Datasheet – CMOS Counter / Divider ( PDF )

Part Number : CD4017B

Function : CMOS Decade Counter with 10 Decoded Outputs

Package : TSSOP 16 Pin Type

Manufacturers : Texas Instruments

Pinouts :

CD4017B datasheet


Description :

CD4017B and CD4022B are 5-stage and 4-stage Johnson counters having 10 and 8 decoded outputs, respectively. Inputs include a CLOCK, a RESET, and a CLOCK INHIBIT signal.

Schmiit trigger action in the CLOCK input circuit provides pulse shaping that allows unlimited clock input pulse rise and fall times.

Features :

1. Fully static operation

2. Medium speed operation…10 MHz (typ.) at VDD = 10 V

3. Standardized, symmetrical output characteristics

4. 100% tested for quiescent current at 20 V

5.  Meets all requirements of JEDEC Tentative Standard No. 13B, “Standard Specifications for Description of ’B’ Series CMOS Devices”

Applications :

1. Decade counter/decimal decode display (CD4017B)

2. Binary counter/decoder

3. Frequency division

4. Counter control/timers

5. Divde-by-N counting

74LS90 Datasheet – Decade Counter – SN74LS90

Part Number : 74LS90


Package : DIP 14 Pin Type

Manufacturers : Texas Instruments

74LS90 datasheet

Description :

Each of these monolithic counters contrains four master-slave flip-flops and additional gating to provice a divide-by-two counter and a three-stage binary counter for which the count cycle length is divide-by-five for 74LS90.

To use their maximum count length ( decade, divide-by-twelve, or four-bit binary) of these counters, the CKB input is connected to the Qa output.

Features :

1. 7490A, SN74LS90N : Decade Counters

2. 7492A, 74LS92 : Divide By-Twelve Counters,

3. 7493A, 74LS93 : 4-bit Binary Counters, SN74LS90N.
