The MC3488A dual is single–ended line driver has been designed to satisfy the requirements of EIA standards EIA–423 and EIA–232D, as well as CCITT X.26, X.28 and Federal Standard FIDS1030. It is suitable for use where signal wave shaping is desired and the output load resistance is greater than 450 ohms. Output slew rates are adjustable from 1.0 ms to 100 ms by a single external resistor. Output level and slew rate are insensitive to power supply variations. Input undershoot diodes limit transients below ground and output current limiting is provided in both output states.
The MC3488A has a standard 1.5 V input logic threshold for TTL or NMOS compatibility.
PNP Buffered Inputs to Minimize Input Loading
Output Levels and Slew Rates are Insensitive to Power Supply Voltages
No External Blocking Diode Required for VEE Supply
