Integrated Circuit Technologies Questions

• A certain gate draws 1.8 µA when its output is HIGH and 3.3 µA when its output is LOW. VCC is 5 V and the gate is operated on a 50% duty cycle. What is the average power dissipation (PD)?
• One output structure of a TTL gate is often referred to as a ________.
• The nominal value of the dc supply voltage for TTL and CMOS is ________.
• If ICCH is specified as 1.1 mA when VCC is 5 V and if the gate is in a static (noncharging) HIGH output state, the power dissipation (PD) of the gate is ________.
• Which is not a precaution for handling CMOS?
• Unused TTL inputs should be tied LOW.
• There are four different logic level ranges for TTL and CMOS: VIL, VIH, VOL, and VOH.
• ECL IC technology is faster than TTL technology.
• The speed-power product provides a basis for the comparison of logic circuits when power dissipation and propagation delay are important considerations in the selection of the type of logic to be used.
• A pull-down resistor must be used with open-collector TTL circuits.
• Power dissipation is a measure of a circuit's noise immunity.
• CMOS is a more dominant IC technology than TTL.
• The total sink current decreases with an increase in each load gate input.
• The greater the propagation delay, the higher the maximum frequency.
• Metal-oxide semiconductor field-effect transistors (MOSFETs) are the active switching elements in CMOS circuits.
