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 T = –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

Note: Lansdale lead free (Pb) product, as it

becomes available, will be identified by a part

number prefix change from ML to MLE.
