Q: 1 Which one is the Unipolar logic family?

RTL
DTL
TTL
NMOS

Show Answer

[ Option D ]

Bipolar:

RTL (Resistor-Transistor Logic)
DTL (Diode-Transistor Logic)
TTL (Transistor-Transistor Logic)
ECL (Emitter-Coupled Logic)
IIL (Integrated Injection Logic)

Unipolar:

NMOS (N-type Metal Oxide Semiconductor)
PMOS (P-type Metal Oxide Semiconductor)
CMOS (Complementary MOS)

Note:

Bipolar families use BJTs (Bipolar Junction Transistors), while unipolar families use MOSFETs (Metal-Oxide Semiconductor FETs) as switching devices.
