Driver/Receiver
EIA 232–E and CCITT V.28 (Formerly RS–232–D)
Legacy Device: Motorola MC145406
The ML145406 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– power–off source impedance, and output typically switching to within 25% of the supply rails. The receivers can handle up to ±25 V while presenting 3 to 7 k impedance. Hysteresis in the receivers aids reception of noisy signals. By combining both drivers and receivers in a single CMOS chip, the ML145406 provides efficient, low–power solutions for EIA 232–E and V .28 applications. This device offers the following performance features: Operating Temperature Range = TA –40° to +85°C Drivers ± 5 V to ±12 V Supply Range 300– Power–Off Source Impedance Output Current Limiting TTL Compatible Maximum Slew Rate = 30 V/s Receivers ± 25 V Input Voltage Range When VDD = 12 V , VSS = – 12 V 3 to 7 k Input Impedance Hysteresis on Input Switchpoint
