The basic part numbers of ICs are the same regardless of the manufacturer because digital logic ICs have been standardized.
In ECL, the HIGH and LOW levels are determined by which transistor in a differential amplifier is conducting more.
How many 74LSTTL logic gates can be driven from a 74TTL gate?
Which of the following logic families has the shortest propagation delay?
Schottky logic overcomes the saturation and stored charge problem by placing a Schottky diode across the base-to-collector junction.
Propagation delay in TTL is due to slow switching speeds.
What is the difference between the 74HC00 series and the 74HCT00 series of CMOS logic?
Why must CMOS devices be handled with care?
Interfacing (74HCMOS to 74ALSTTl or 74TTL to 74LSTTL) can be done with no danger.
In TTL the noise margin is between 0.8 V and 0.4 V.
Special handling precautions should be taken when working with MOS devices. Which of the following statements is not one of these precautions?
A pulse is not perfectly square; it takes time for the digital level to rise from 0 up to 1 and to fall from 1 down to 0.
The AND is the simplest of the gates, requiring the least amount of circuitry to implement in TTL.
Why are the maximum value of VOL and the minimum value of VOH used to determine the noise margin rather than the typical values for these parameters?
PMOS and NMOS are commonly used for small memories and microprocessors.
A typical fan-out for most TTL is 9.
What should be done to unused inputs on TTL gates?
