MAX200CPP

Drivers, Receivers, Transceivers Overview

The MAX200CPP is a five-driver, zero-receiver RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply using an integrated charge pump to generate ±10V internal rails, requiring four external 0.1µF capacitors. The device provides five TTL/CMOS-compatible drivers with 400kΩ pullup resistors and meets EIA/TIA-232E output levels exceeding ±5V at data rates over 120kbps. It features a low-power shutdown mode reducing current to 1µA typical. Packaged in a 20-pin Plastic DIP (PDIP), it supports an operating temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump eliminates the need for bipolar ±12V supplies
• Low-power shutdown mode reduces supply current significantly
• TTL and CMOS input logic compatibility
• Internal pullup resistors on driver inputs

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment
• Handheld equipment
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix CPP corresponds to the 20-pin Plastic DIP package and commercial temperature grade. Check for RoHS compliance status as indicated in official documentation, noting that older batches may not meet current environmental standards.

Drivers, Receivers, Transceivers Selection Notes

Select this component when five independent transmit lines are required without receiver capability. Ensure the application utilizes a stable +5V power source. Verify that the PCB layout accommodates four external 0.1µF capacitors for the charge pump circuit. Consider the 20-pin PDIP footprint constraints during mechanical design integration.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209/MAX211/MAX213 family of +5V RS-232 transceivers. Unlike other members such as the MAX203 which requires no external components, the MAX200 specifically requires four external capacitors. It differs from the MAX211 by lacking receivers and utilizing a 20-pin package instead of 28-pin options.

Drivers, Receivers, Transceivers FAQ

What is the function of the SHDN pin?

Driving the SHDN pin high activates low-power shutdown mode, turning off the charge pumps and disabling transmitter outputs to reduce supply current.

How are unused driver inputs handled?

Unused driver inputs can be left unconnected because internal 400kΩ pullup resistors to VCC force the outputs low, minimizing power consumption.

What is the maximum data rate supported?

The device supports data rates in excess of 120kbps when loaded according to EIA/TIA-232E specifications.
