Very essential & vital training board in digital
electronics lab for verification of truth table for various Logic
gates. student will make connections themselves with the help of
interconnection leads and verify De-morgan's theorm and unravel
mystery of boolean algebra. Standard 7400 series T.T.L. IC's are
used Bounceless data switches and buffered LED indicators are also
1. 2 input AND Gates (IC used 74LS08) - 4No.
2. 2 input NAND Gates (IC used 74LS00) - 2No.
3. 3 input NAND Gates (IC used 74LS10) - 3No.
4. 2 Input OR Gates (IC used 74LS32) - 4No.
5. 1 Input NOT Gates (Logic Inverters, 74LS04) - 6No.
6. 3 Input NOR Gates (IC used 74LS27) - 3No.
7. 4 Bounceless Logic input switches with complementary outputs.
8. 4 Buffered LED Logic indicators.
9. interconnection leads - 25 No.
10. comprehensive User's Manual - 1 No.
Functional Diagrams of all Logic gates are nicely
printed on front panel board. Brass socket of 2mm inner diameter
are press mounted on bakelite panel by special techniques and corresponds
to various pins of functional diagram.
