Drivers/Receivers  
RS 232/EIA–232–E and CCITT V.28  
Legacy Device: Motorola MC145403, MC145404, MC145405, MC145408  
These devices are silicon gate CMOS ICs that combine both the  
transmitter and receiver to fulfill the electrical specifications of EIA  
Standard 232–E and CCITT V.28. The drivers feature true TTL input  
compatibility, slew rate limiting outputs, 300 power–off source  
impedance, and output typically switching to within 25% of the sup-  
ply rails. The receivers can handle up to 25 V while presenting 3 to  
7 kimpedance. Hysteresis in the receivers aid in the reception of  
noisy signals. By combining both drivers and receivers in a single  
CMOS chip, these devices provide efficient, low–power solutions for  
both EIA–232–E and V.28 applications.  
These devices offer the following performance features:  
• Operating Temperature Range T = –40° to +85°C

Drivers  
5 to 12 V Supply Range  
• 300 Power–Off Source Impedance  
• Output Current Limiting  
• TTL and CMOS Compatible Inputs  
• Driver Slew Rate Range Limited to 30 V/µs Maximum  
Receivers  
25 V Input Range  
• 3 to 7 kInput Impedance  
• 0.8 V of Hysteresis for Enhanced Noise Immunity  
• TTL and CMOS Compatible Outputs
