Jlab Export is a leading To study and verify truth table of 4 bit Up and Down counter using IC 74193 Manufacturer,and suppliers in India
To study and verify truth table of 4 bit Up and Down counter using IC 74193 (code EL-DEECP-1176) is a digital electronics trainer built around the IC 74193 for verifying the truth table of a 4-bit counter that counts up or down. It has a 1 Hz clock pulse, four output indicators, four SPDT logic switches and separate switches for up/down selection and reset, for counter practicals in college, polytechnic and ITI labs. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the IC 74193 Up/Down Counter Trainer Used For?
The 74193 is a synchronous 4-bit up/down binary counter: all four of its flip-flops change on the same clock edge, so there is no ripple delay between stages. It has separate count-up and count-down clock inputs, a clear (reset) input, four data inputs that can be loaded to preset a starting value, and carry and borrow outputs for cascading two or more counters. With the 1 Hz clock, students watch the four output indicators step through all sixteen states, switch the direction to count back down, and use the reset switch to return to zero before writing out the truth table for each direction.
The printed diagram of the IC 74193 and the sockets for inputs and outputs let students trace each pin, while the four SPDT switches give logic 1 or 0 levels for the inputs. The practical fits digital electronics courses in B.Sc. physics and electronics, engineering diplomas and ITI electronics trades, and pairs well with a ripple counter built from separate flip-flops.
What to Specify When Ordering
- Mains supply — the listing does not give the power input, so state your voltage.
- Comparison set — add the ripple counter trainer if you want students to compare synchronous and asynchronous counting.
- Quantity — the minimum order is 10 units.
Frequently Asked Questions
Which IC does this counter trainer use?
The IC 74193, a synchronous 4-bit up/down binary counter; its circuit diagram is printed on the trainer.
How is the counting direction chosen?
With a dedicated switch for up or down counting; a second switch resets the counter.
What clock does it use?
A 1 Hz clock pulse, so each change of state can be read on the four output indicators.
How does it differ from the 4-bit ripple counter trainer?
The ripple counter trainer chains four separate JK flip-flops, each clocked by the stage before it, so its outputs settle one after another. This trainer uses one synchronous counter IC in which all bits change together, with switches for direction and reset.
What details should an export enquiry include?
The quantity, destination country and port or city, delivery terms such as FOB or CIF, labelling needs and any tender reference.
Who manufactures this trainer?
JLab, the trading name of Jain Laboratory Instruments Pvt Ltd, at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electronics and laboratory teaching equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The counter trainer is built at JLab’s own works, not resold from a trader, so institutions, dealers and importers buy direct from the maker, each unit is checked before dispatch, and repeat orders stay with the same manufacturer. The company is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise. JLab exports worldwide and ships to buyers in every region — for example Belgium in Western Europe, the USA in North America, Italy in Southern Europe, Niger in West Africa and Slovakia in Eastern Europe. Tender information is on the JLab lab tenders page.
