MAX206EWG

Drivers, Receivers, Transceivers Overview

The MAX206EWG+ is a +5V RS-232 transceiver featuring four drivers and three receivers in a 24-pin SOIC package. It supports data rates up to 120kbps with an operating temperature range of -40°C to +85°C. The device operates on a single +5V supply, utilizing an integrated charge pump to generate ±10V internally. Key electrical parameters include a typical supply current of 20mA, a shutdown mode current of 1µA, and a propagation delay of 10µs. It requires four external 0.1µF capacitors for the voltage converters.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for bipolar ±12V supplies, enabling single +5V operation.
• Low-power shutdown mode significantly reduces supply current for extended battery life in portable applications.
• TTL/CMOS compatible inputs feature internal pullup resistors to ensure defined states when unused.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low standby power consumption
• Handheld devices and portable diagnostic tools
• RS-232 serial communication interfaces in space-constrained designs

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EWG+' against the manufacturer's latest documentation to confirm the exact package type (SOIC) and temperature grade (-40°C to +85°C). Ensure that the required four external 0.1µF capacitors are included in the bill of materials, as they are essential for the internal charge pump functionality.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a full-duplex RS-232 interface with four transmit and three receive channels is required. It is suitable for designs constrained by board space due to the compact SOIC packaging. Consider the 120kbps maximum data rate and the necessity for external capacitors when evaluating alternative transceivers.

Drivers, Receivers, Transceivers Part Context

The MAX206 belongs to the MAX200-MAX209 family of +5V RS-232 transceivers. This series is characterized by its ability to operate from a single supply using internal charge pumps. The MAX206 specifically provides a higher channel count compared to simpler variants like the MAX202, offering greater flexibility in complex serial communication systems.

Drivers, Receivers, Transceivers Replacement Considerations

The ADM206ARZ is a pin-compatible alternative from Analog Devices. Verify that the replacement supports the same 120kbps data rate and operates within the required -40°C to +85°C temperature range. Confirm that the external capacitor requirements and pinout configuration remain identical for direct substitution.
