Logic Families and Their Characteristics - Technical MCQs
Q1: The problem of interfacing IC logic families that have different supply voltages (VCC's) can be solved by using a:A
level-shifter
B
tristate shifter
C
decoupling capacitor
D
pull-down resistor
ANS:A - level-shifter Like MAX232 by TEXAS INSTRUMENTS. From CMOS TO TTL logic conversion especially using serial communication interfacing via RS232 standards. |
