MAX242CPN+

Overview

The MAX242CPN+ is a +5V-powered, multichannel RS-232 transceiver featuring two drivers and two receivers. It operates within a supply voltage range of 4.5V to 5.5V with a typical operating current of 10mA. The device supports data rates up to 200kb/s and includes an integrated shutdown mode for power reduction. Transmitter propagation delay ranges from 1.3µs to 3.5µs, while receiver propagation delay is between 0.5µs and 1µs. It utilizes external capacitors for its internal charge pump and is housed in an 18-pin PDIP package.

Feature Summary

Integrated charge pump circuitry eliminates the need for bipolar ±12V supplies, enabling single +5V operation.
Shutdown mode significantly reduces power consumption for battery-operated applications.
Provides EIA/TIA-232E compliance for standard serial communication interfaces.

Applications

Interface translation between TTL/CMOS logic and RS-232 standards
Multidrop RS-232 network connections
Portable diagnostics equipment

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices prior to procurement. Ensure the specific ordering suffix matches the required temperature grade and packaging format for your design requirements.

Selection Notes

Select this component when designing systems requiring dual-channel RS-232 communication powered by a single +5V rail. It is suitable for applications where board space is limited but external charge pump capacitors are acceptable. Compare against MAX232 variants if higher data rates or different pin configurations are needed.

Part Context

This part belongs to the MAX220–MAX249 family of line drivers and receivers designed for EIA/TIA-232E and V.28/V.24 interfaces. The family offers various channel counts and packages to accommodate different system integration needs without requiring external high-voltage generation components.
