The following is an internal schematic of a TTL logic gate. Based on your analysis of the transistor circuit, determine what type of gate (AND, OR, NAND, NOR, XOR, etc.) it is: Hint: the double-emittertransistoris being used as a pair of diodes, and not as an amplifying device!
A TTL NAND gate can be made by taking a TTL inverter circuit and adding another input. An AND gate may be created by adding an inverter stage to the output of the NAND gate circuit. RELATED WORKSHEET: TTL Logic Gates Worksheet Lessons in Electric Circuits ...
