Driver/Receiver(EIA 232-E and CCITT V.28(Formerly RS-232-D)
EIA 232–E and CCITT V.28 (Formerly RS–232–D)The MC145406 is a silicon–gate CMOS IC that combines three drivers
and three receivers to fulfill the electrical specifications of standards
EIA 232–E and CCITT V.28. The drivers feature true TTL input
compatibility, slew–rate–limited output, 300–Ω power–off source imped-
ance, and output typically switching to within 25% of the supply rails. The
receivers can handle up to ±25 V while presenting 3 to 7 kΩ 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–power solutions for EIA 232–E and V.28 applications.
Drivers •± 5 V to ±12 V Supply Range 300–Ω Power–Off Source Impedance Output Current Limiting TTL Compatible Maximum Slew Rate = 30 V/μs
Receivers •± 25 V Input Voltage Range When VDD = 12 V, VSS = – 12 V 3 to 7 kΩ Input Impedance Hysteresis on Input Switchpoint
