145406 - MC145406

Datasheet Summary

Description

The most positive power supply pin, which is typically + 5 to + 12V.

5 to

12 V.

Features

  • Tx output to swing toward VSS. A logic 0 causes the output to swing toward VDD (the output voltages will be slightly less than VDD or VSS depending upon the output load). Output slew rates are limited to a maximum of 30 V per µs. When the MC145406 is off (VDD = VSS = VCC = GND), the minimum output impedance is 300 Ω.

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145406/D Driver/Receiver 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 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 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.
