TTL and CMOS Characteristic Trainer Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12760
Indian Lab Suppliers supplies the TTL and CMOS Characteristic Trainer (Product ID: 12760) as part of its electronics engineering lab equipment range. It measures voltage transfer characteristics, noise margins and propagation delay of TTL and CMOS gates, including Schmitt-trigger types.
Quick Answer
The voltage transfer characteristic plots gate output voltage against input voltage. Noise margin is the safety gap between worst-case output levels and the levels an input needs: NMH = VOH − VIH and NML = VIL − VOL. Gate delay is the time from a stable input change to a stable output. These are studied on TTL and CMOS NAND and NOT gates and their Schmitt-trigger versions, using the built-in 5 V and 12 V supplies, 0–5 V and 0–12 V variable supplies and a 100 Hz, 0–5 Vpp pulse generator. It runs from 230 V ±10%, 50 Hz and weighs about 1 kg.

An oscilloscope is normally needed to measure gate delay. Browse the full Electronics Engineering Lab Equipment range or related Electronics Lab Equipment products.
Frequently Asked Questions
What does a Schmitt-trigger gate change?
It has different switching thresholds for rising and falling inputs (hysteresis), which rejects noise.
How is noise margin found?
From the transfer characteristic, as VOH − VIH and VIL − VOL.
What pulse source is built in?
A 100 Hz pulse generator adjustable to 5 Vpp.
