4-Bit Binary Decade Up/Down Counter using IC 74192 Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12729
Indian Lab Suppliers supplies the 4-Bit Binary Decade Up/Down Counter using IC 74192 (Product ID: 12729) as part of its electronics engineering lab equipment range. It demonstrates up counting, down counting and presetting with the presettable BCD decade up/down counter IC 74192.
Quick Answer
The 74192 is a synchronous decade counter: it counts up from 0 to 9 or down from 9 to 0 and gives a 4-bit BCD output. Students also load a preset value through its four parallel inputs, clear it with the master reset, and follow the count sequence from that point. SPDT, DPDT and micro switches set the logic levels and clock, a quad 2-input NAND gate IC completes the circuit, and LEDs show the output state. A 5 V DC, 200 mA regulated supply is built in; the board runs from 230 V ±10%, 50 Hz mains.

Frequently Asked Questions
Does it count in pure binary to 15?
No. The 74192 is a decade counter, so it counts 0–9 in BCD; a 0–15 binary count needs its sister IC 74193.
Can the counter be preset?
Yes, through four parallel inputs and a load control.
How is the count displayed?
On LEDs showing the 4-bit BCD output.
