Interfacing CMOS IC's to TTL & TTL to CMOS IC's Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12738
Indian Lab Suppliers supplies the Interfacing CMOS IC's to TTL & TTL to CMOS IC's (Product ID: 12738) as part of its electronics engineering lab equipment range. It covers the circuits needed to drive CMOS from TTL and TTL from CMOS when the two families run at different voltages.
Quick Answer
A TTL high output may sit below the input-high threshold of CMOS, especially when the CMOS runs at 12 V, so a pull-up to the CMOS supply through an open-collector TTL gate is used; going the other way, a transistor stage can shift CMOS levels and supply the current a TTL input needs. The board provides 5 V and 12 V DC (30 mA each) regulated supplies, a 0–12 V, 30 mA variable supply, and quad 2-input NAND gates in standard TTL, open-collector TTL and CMOS form, plus a transistor. It runs from 230 V ±10%, 50 Hz mains, with patch cords (4 mm stackable plugs, ½ m).
