MC1488P Quad Line Driver 15V 10mA DIP-14
The MC1488P is a monolithic quad line driver designed for RS-232C data communication interfaces. It contains four driver circuits and converts DTL/TTL logic levels into RS-232C-compatible signal levels with one stage of inversion. The device is designed to interface data terminal equipment with data communications equipment according to the EIA RS-232C standard.
The device features current-limited outputs, TTL- and microprocessor-compatible inputs, power-off output impedance, and slew-rate control using external capacitors. The datasheet specifies the MC1488P in a 14-pin plastic DIP package, with an operating ambient temperature range of 0°C to 75°C.
Features:
- Current limited output ±10mA typ.
- Power-off source impedance 300Ω min.
- Simple slew rate control with external capacitor
- Flexible operating supply range
- Inputs are TTL and µP compatible
