Driver/Receiver
EIA 232鈥揈 and CCITT V.28 (Formerly RS鈥?32鈥揇)
The MC145406 is a silicon鈥揼ate CMOS IC that combines three drivers
and three receivers to fulfill the electrical specifications of standards
E I A 2 3 2 鈥?E a n d C C I T T V. 2 8 . T h e d r i v e r s f e a t u r e t r u e T T L i n p u t
compatibility, slew鈥搑ate鈥搇imited output, 300鈥撯劍 power鈥搊ff source imped-
ance, and output typically switching to within 25% of the supply rails. The
receivers can handle up to
鹵
25 V while presenting 3 to 7 k鈩?impedance.
Hysteresis in the receivers aids reception of noisy signals. By combining
both drivers and receivers in a single CMOS chip, the MC145406 provides
efficient, low鈥損ower solutions for EIA 232鈥揈 and V.28 applications.
