Advance Level Logic Trainer Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12755
Indian Lab Suppliers supplies the Advance Level Logic Trainer (Product ID: 12755) as part of its electronics engineering lab equipment range. It covers retriggerable monostables, synchronous and series-parallel counters, serial-to-parallel conversion, static RAM read/write and I/O-port concepts on one board.
Quick Answer
Students design, build and test a retriggerable monostable using IC 555 with LED output; synchronous 4-stage binary up, down and up/down counters with parallel and series carry, and a 4-stage synchronous decade counter; 3-stage mod-5 and 4-stage mod-10 series-parallel counters; and a serial-to-parallel data converter. Write and read cycles are carried out on a 1024 × 4-bit static RAM (2114), and the input and output modes of the 8212 I/O port are studied with a 74244 tristate buffer on the bus. The board has four JK master-slave flip-flops with preset and clear, five 2-input and four 4-input NAND gates, a 1 kHz square-wave generator, 5 V (200 mA) and 10 V (100 mA) regulated supplies, and 2 mm patch cords; it runs from 230 V ±10%, 50 Hz mains.

Frequently Asked Questions
What makes a 555 monostable retriggerable?
In the usual circuit a transistor discharges the timing capacitor at each new trigger, so the pulse restarts before it ends.
What memory IC is used?
A 2114 static RAM organised as 1024 × 4 bits.
What is the difference between parallel and series carry?
With parallel carry each stage gets its enable directly from all lower stages; with series carry the enable ripples through gates from stage to stage.
