74HCT4040N Datasheet PDF – 12-Stage Binary Ripple Counter

Part Number : 74HCT4040N

Function : 12-stage binary ripple counter

Package : DIP 16 Pin Type

Manufacturers : Philips Electronics


74HCT4040N datasheet



Description :

The 74HC4040, 74HCT4040 is a 12-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and twelve parallel outputs (Q0 to Q11).

The counter advances on the HIGH-to-LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of the state of CP. Each counter stage is a static toggle flip-flop. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.

74LS193 Datasheet – Binary UP/Down Counter – Motorola

Part Number : 74LS193

Function : UP/DOWN MODULO-16 Binary Counter

Package : DIP, SOIC 16 Pin

Manufacturers : Motorola ( Freescale )

Pinouts :

74LS193 datasheet

Description :

TheSN54/74LS192 is an UP/DOWN BCD Decade (8421) Counter and the SN54/74LS193 is an UP/DOWN MODULO-16 Binary Counter. Separate CountUp and Count Down Clocks are used and in either counting mode the circuits operate synchronously. The outputs change state synchronous with the LOW-to-HIGH transitions on the clock inputs.


1. Low Power : 95 mW Typical Dissipation
2. High Speed : 40 MHz Typical Count Frequency
3. Synchronous Counting
4. Asynchronous Master Reset and Parallel Load
5. Individual Preset Inputs
6. Cascading Circuitry Internally Provided
