MAX208ENG

Drivers, Receivers, Transceivers Overview

The MAX208ENG is a +5V RS-232 transceiver from the Analog Devices/MAXIM family, featuring four drivers and four receivers. It operates with a single +5V supply using integrated charge-pump circuitry to generate ±10V internally, requiring only four 0.1µF external capacitors. The device supports data rates exceeding 120kbps and maintains ±5V output levels under EIA/TIA-232E specifications. It includes TTL/CMOS-compatible inputs with internal pullup resistors for unused drivers. The 'E' suffix indicates an extended temperature range of -40°C to +85°C.

• Single +5V operation capability
• TTL/CMOS input compatibility

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type associated with the ENG suffix against official documentation, as standard variants often utilize SSOP or DIP formats. Confirm that the component matches the intended thermal requirements for the specified industrial temperature range before integration into final designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple serial channels on a single +5V rail. Ensure adequate decoupling capacitors are placed near the V+ and V- pins to maintain stable internal voltage generation during high-speed data transmission periods.

Drivers, Receivers, Transceivers Part Context

This part belongs to the broader MAX200-MAX209 series of RS-232 transceivers. These components share common architecture regarding charge-pump functionality and signal inversion characteristics. The MAX208 specifically provides four independent transmit and receive channels within a compact footprint suitable for dense PCB layouts.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other members of the MAX200-MAX209 family such as the MAX208CNG or MAX208EAG, provided pinout and electrical specifications remain identical. Verify package dimensions carefully when substituting between SO and SSOP variants.
