MAX1488ECPD

The MAX1488ECPD is a high-speed, low-power, three-channel, EIA/TIA-232E-compliant line driver/receiver IC with an integrated chip driver in a Tiny Outline package. It is designed to interface +5-V logic devices with EIA/TIA-232E-compliant devices. The MAX1488ECPD offers the user fully protected outputs, glitch-free shutdown and a low power shutdown mode.

The MAX1488ECPD is constructed with a flexible, low-power CMOS process and is capable of operating over a wide range of input, output, supply and temperature conditions. It operates with a single +5-V supply and incorporates TTL logic thresholds which provide a low standby current and high logic levels. The MAX1488ECPD is available in a tiny 8-pin SOIC package.

MAX1488ECPD Application Field

The MAX1488ECPD is suitable for many applications such as, but not limited to: communication line receivers, line drivers and bus controllers for fibre-optic systems, consumer, industrial, computers and peripheral devices, audio and video equipment, process control, long distance telephone and modems and serial data communication links.

The MAX1488ECPD is ideal for any application which requires EIA/TIA-232E-compliant drivers and receivers in a tiny package. It has high data rates and wide common-mode input voltage ranges. It is designed for single +5-V supply applications and is available in CMOS version for greater power savings over TTL versions.

MAX1488ECPD Working Principle

The MAX1488ECPD includes three drivers and one receiver in an 8-pin SOIC package. The drivers have three independent channels with TTL compatible inputs and EIA/TIA-232E-compliant outputs. The receiver has one EIA/TIA-232E-compliant input and one TTL compatible output.

The MAX1488ECPD works on the principle of charge-pump voltage conversion. An oscillator-regulated charge pump is used to generate the required power-supply voltages needed by the drivers. This eliminates the need for external voltage-doubler or voltage regulator components.

The adjustable receiver input threshold allows for a wide range of input signals to be accepted. The outputs are protected against short circuits, open circuits and over-temperature conditions.

Conclusion

The MAX1488ECPD is an 8-pin, EIA/TIA-232E-compliant line driver/receiver IC. It is designed to interface TTL logic devices with power efficient EIA/TIA-232E-compliant devices. It is suitable for a number of applications including communication line receivers, line drivers and bus controllers for fibre-optic systems, consumer, industrial, computers and peripheral devices, audio and video equipment, process control, long distance telephone and modems, and serial data communication links. The MAX1488ECPD works on the principle of charge-pump voltage conversion and its adjustable receiver input threshold allows for a wide range of input signals to be accepted.
