Totem pole ttl output9/24/2023 In the circuit shown in the figure, each emitter of transistor T 1 acts as a diode, so transistor T 1 and the 4K Ohm resistor act as a 2 input NAND gate. The multiple emitter system is a specialty of the TTL 7400 series. In this circuit, instead of the input diode used in DTL circuits, a multiple emitter configuration is used, due to which high switching speed is achieved. Totempole ‘AND’ gateĪ TTL NAND gate is shown in the figure. Many types of SSI and MSI chips are available in this TTL range, through which almost all types of digital circuits can be made. The 7400 series of the TTL family was introduced in 1964 by Texas Instruments. Click Here to read this article in Hindi. The main reason for the slow speed in DTL is the slow removal of stored base charge at the base of the output transistor. What is Transistor Transistor Logic ? | TTLĭue to limited speed, DTL is now out of use area (obsolete) and in its place another logic family Transistor Transistor Logic (TTL) is widely used.
