What is 74LS192?

What is 74LS192?

The SN54/74LS192 is an UP/DOWN BCD Decade (8421) Counter and the SN54/74LS193 is an UP/DOWN MODULO-16 Binary Counter. Individual preset inputs allow the circuits to be used as programmable counters. Both the Parallel Load (PL) and the Master Reset (MR) inputs asynchronously override the clocks.

How does the 74192 74193 counter control counting up or down?

The 74192 is a BCD decade up/down synchronous counter. The 74193 is a 4-bit binary up/down synchronous counter. These chips also have parallel data input leads that can be used to preset the counter. A terminal count UP and a terminal count DOWN output signal can be used to cascade several ICs together.

What does an up down counter do?

Counters are used in many different applications. Some count up from zero and provide a change in state of output upon reaching a predetermined value; others count down from a preset value to zero to provide an output state change. The counters can be cascaded in high-speed mode. …

What is 74HC192?

The 74HC192 is asynchronously presettable BCD Decade and Binary Up/Down synchronous counters, respectively. Presetting the counter to the number on the preset data inputs (P0-P3) is accomplished by a LOW asynchronous parallel load input (PL)\.

How does a 74192 IC work?

The 74192 is a Presettable Synchronous 4-Bit Up/Down Decade Counter. A high level on the CLR input overrides any other input to clear the counter to its zero state. The Terminal Count up (CO) goes low half a clock period before the zero count is reached and returns to a high level at the zero count.

Which counter IC can be used to design preset table counter?

The 74LS90 integrated circuit is basically a MOD-10 decade counter that produces a BCD output code. The 74LS90 consists of four master-slave JK flip-flops internally connected to provide a MOD-2 (count-to-2) counter and a MOD-5 (count-to-5) counter.

What is the difference between 7490 and 7493?

Explanation: The difference between a 7490 and a 7493 is that 7490 is a MOD-10, 7493 is a MOD-16 counter. Thus, 7490 traverses 10 states and 7493 traverses 16 states.

Is up-down counter synchronous?

Both Synchronous and Asynchronous counters are capable of counting “Up” or counting “Down”, but their is another more “Universal” type of counter that can count in both directions either Up or Down depending on the state of their input control pin and these are known as Bidirectional Counters.

What an up-down counter also known as?

Explanation: UP-DOWN counter is also known as multimode counter because it has capability of counting upward as well as downwards. Explanation: In DOWN-counter, each flip-flop is triggered by the inverted output of the preceding flip-flop. DOWN-counter counts from a maximum value to 0.

How does IC 74192 work?

What is up counter and down counter?

An up-counter counts events in increasing order. A down-counter counts stuff in the decreasing order. An up-down counter is a combination of an up-counter and a down-counter. It can count in both directions, increasing as well as decreasing.
