The ML145406 is a siliconu2013gate CMOS IC that combines three drivers andthree receivers to fulfill the electrical specifications of standards EIA 232u2013Eand CCITT V.28. The drivers feature true TTL input compatibility,slewu2013rateu2013limited output, 300u2013u2126poweru2013off source impedance, and output typ-ically switching to within 25% of the supply rails. The receivers can handle upto u00b125 V while presenting 3 to 7 ku2126impedance. Hysteresis in the receiversaids reception of noisy signals. By combining both drivers and receivers in asingle CMOS chip, the ML145406 provides efficient, lowu2013power solutions forEIA 232u2013E and V.28 applications.
