1. A TTL gate may operate inadvertently as an ____________
a) Digital amplifier
b) Analog amplifier
c) Inverter
d) Regulator
Explanation: A TTL gate may operate inadvertently as an analog amplifier if the input is connected to a slowly changing input signal that traverses the unspecified region from 0.7V to 3.3V.
2. The speed of ______ circuits is limited by the tendency of common emitter circuits to go into saturation.
a) TTL
b) ECL
c) RTL
d) DTL
Explanation: The speed of TTL circuits is limited by the tendency of common emitter circuits to go into saturation due to the injection of minority carriers into the collector region. Hence, it functions slowly compared to CMOS devices.
3.The full form of IIL is __________
a) Injection integrated logic
b) Integrated inspected logic
c) Integrated injection logic
d) Injection Inspected Logic
Explanation: The full form of IIL is Integrated injection logic. It is made up of multiple bipolar junction transistors and had a speed comparable to TTl and power consumption equivalent to CMOS
4. Integrated injection logic is a class of digital circuits built with __________
a) Single collector BJT
b) Double emitter BJT
c) Multiple emitter BJT
d) Multiple collector BJT
Explanation: Integrated injection logic is a class of digital circuits built with multiple collector bipolar junction transistors (BJT).
5. IIL has _____ noise immunity.
a) High
b) Low
c) Neutral
d) Nil
Explanation: The full form of IIL is Integrated injection logic. It is made up of multiple bipolar junction transistors and had speed comparable to TTl and power consumption equivalent to CMOS. IIL has high noise immunity because it operates by current instead of voltage.
6. IIL is sometimes also known as __________
a) Single transistor logic
b) Multiple transistor logic
c) Merged transistor logic
d) Mixed Transistor Logic
Explanation:The full form of IIL is Integrated injection logic. It is made up of multiple bipolar junction transistors and had speed comparable to TTl and power consumption equivalent to CMOS. IIL is sometimes also known as merged transistor logic.
7. Integrated Injection logic cannot be denoted as __________
a) IIL
b) I2L
c) I2L
d) I TWO L
Explanation: The full form of IIL is Integrated injection logic. It is made up of multiple bipolar junction transistors and had speed comparable to TTl and power consumption equivalent to CMOS. Integrated Injection logic can be denoted as IIL, I2L and I2L as well.
8. The heart of an I2L circuit is the __________
a) Common collector open emitter inverter
b) Common emitter open collector inverter
c) Open emitter common collector inverter
d) Open Emitter Open Collector Inverter
Explanation: The heart of an I2L circuit is the common emitter open collector inverter. The emitter is connected to the ground, with the base having an input behaving as either current sink or high impedance floating condition. The output of an inverter is connected to the collector.
9. In Integrated Injection, logic input is supplied to the __________
a) Emitter
b) Base
c) Collector
d) Collector Emitter
Explanation: In IIL, the input is supplied to the base as either a current sink (low logic level) or as a high impedance floating condition (high logic level). The output of an inverter is connected to the collector.
10. In Integrated Injection, logic output is received through the __________
a) Emitter
b) Base
c) Collector
d) Base Emitter Junction
Explanation: In Integrated Injection logic output is received through the collector. The output of an inverter is connected at the collector.
