The MC1488 is a monolithic quad line driver designed to interface data terminal equipment (DTE) with data communications equipment (DCE) in conformance with the specifications of EIA Standard No. EIA-232D.
The MC1488 is a monolithic quad line driver designed to interface data terminal equipment with data communications equipment in compliance with the EIA‑232D specification. It features a current‑limited output, power‑off source impedance, simple slew‑rate control, and a flexible operating supply range, and is compatible with all ON Semiconductor MDTL and MTTL logic families.
The datasheet provides maximum ratings, electrical and switching characteristics, application guidelines, ordering information, and package dimensions. It also includes typical performance curves for output voltage, slew rate, and propagation delay, as well as recommendations for power‑supply protection and optional external components.
| Current Limited Output | +10 mA typical |
|---|---|
| Operating Supply Voltage | +15 V to –15 V |
| Input Current (Low Logic) | 1.6 mA typ |
The device can operate with a positive supply up to +15 V and a negative supply down to –15 V.
The output current is limited to about 10 mA typical, with a maximum of 12 mA under certain conditions.
