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
7. Input Clamp Diodes Limit High Speed Termination Effects
