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 µs to
100 µs 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

• Short Circuit Protection

• Adjustable Slew Rate Limiting

• MC3488A Equivalent to 9636A

• Output Levels and Slew Rates are Insensitive to Power

Supply Voltages

• No External Blocking Diode Required for V

• Second Source µA9636A
