Dual EIA-423/EIA-232D

Line Driver

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 VEE Supply

• Second Source µA9636A
