Logic Families and Their Characteristics - Technical MCQs

Q1:

Assume that a particular IC has a supply voltage (Vcc) equal to +5 V and ICCH = 10 mA and ICCL = 23 mA. What is the power dissipation for the chip?

A 50 mW

B 82.5 mW

C 115 mW

D 165 mW

ANS:B - 82.5 mW

Icc=IccH+IccL/2.
Icc=(10+23)/2.
=33/2.
=16.5.
Power dissipation =Icc*Vcc.
=16.5*5.
=82.5.
