Very essential & vital training board in digital electronics
lab for varification of truth table for various Logic gates.
Student will make connections themselves with help of interconnection
leads and varify De-morgan's therom 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) -4 No.
2. 2 Input NAND Gates (IC used 74LS00) -2 No.
3. 3 Input NAND Gates (IC used 74LS10) -3 No.
4. 2 Input OR Gates (IC used 74LS32) -4 No.
5. 1 Input NOT Gates (Logic Inverters, 74LS04)
6. 3 Input NOR Gates (IC used 74LS27) -3 No.
7. 4 Bounceless Logic input switches with complementary
8. 4 Buffered LED Logic indicators.
9. Interconnection leads - 25 No.
10. Comprehensive User's Manual - 1No.
Functional Diagrams of all Logic gates are nicely printed
on front panel board. Brass sockets of 2mm inner diameter
are press mounted on bakelite panel by special techniques
and corresponds to various pins of functional diagram.
