about 4033 IC....

Can the 4033 ic hold the out put???
if yes then what'll be the circuit?plz post a circuit.i need it very much for a frequency counter.

It can only hold the output when it is not counting. If you need to hold the previous value while counting, you will need a counter with output latches such as the CD40110.

Take a look here.

Is it same as 4026? in 4026 holds the data when clock is disable.

if i'm using 4510 and 4511, will it help me? bcz i think 4511 can hold the display, even in the counting is on.

 

[crutschow]

I not referring to holding the data when the clock is disabled. All counters do that.

The 4511 has a latch, so that, along with the 4510, will also hold the last count while you are doing the next count (with the proper latch signal).

Ok.then. i just see the pin details for 40110, what does the pin 'toggle enable' and 'borrow' do?

 

[crutschow]

The "toggle enable" enables the counting when at a logic low. It stops the counting when at a logic high.

If you look at Figure 15 in the data sheet (reading the complete data sheet is always helpful ) you will see how to connect the 'borrow' and 'carry' signal when cascading more than one counter.

ok. sure....
