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.

Features

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

74LS193 Datasheet PDF – 4-Bit Up/Down Binary Counter

Part Number : 74LS193

Function : Synchronous 4-Bit Up/Down Binary Counters with Dual Clock

Package : DIP 16 Pin

Manufacturers : National Semiconductor ( Texas Instruments )

Pinouts :

74LS193 datasheet

 

Description :

This circuit is a synchronous up/down 4-bit binary counter. Synchronous operation is provided by having all flip-flops clocked simultaneously, so that the outputs change together when so instructed by the steering logic. This mode of operation eliminates the output counting spikes normally as sociated with asynchronous (ripple-clock) counters.

The outputs of the four master-slave flip-flops are triggered by a low-to-high level transition of either count (clock) input. The direction of counting is determined by which count input is pulsed while the other count input is held high.

Features

1. Fully independent clear input
2. Synchronous operation
3. Cascading circuitry provided internally
4. Individual preset each flip-flop
