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 Ω 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 kΩ impedance. 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 TA = –40° to +85°C
Drivers
• ± 5 to ± 12 V Supply Range
• 300 Ω 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 kΩ Input Impedance
• 0.8 V of Hysteresis for Enhanced Noise Immunity
• TTL and CMOS Compatible Outputs

* Voltage specifications are in terms of absolute values.
** Specification is for one Tx output pin to be shorted at a time. Should all three driver outputs be shorted simultaneously, device power dissipation
limits will be exceeded.
