Overview
The MAX236ENG is a +5V-powered, multichannel RS-232 line driver/receiver from the MAX220–MAX249 family. It operates on a single +5V supply and utilizes an integrated charge pump to generate ±10V for RS-232 signaling without external bipolar supplies. The device features four drivers and four receivers with TTL/CMOS-compatible inputs and outputs. It supports data rates up to 120 kbps and includes shutdown modes for power reduction. The ENG suffix indicates operation in the -40°C to +85°C temperature range within a 24-pin SOIC package.
Feature Summary
- Integrated charge-pump circuitry eliminates the need for external bipolar voltage sources
- Enables single-supply operation using only a +5V input
- Includes dedicated enable control pins for selective transmitter and receiver activation
Applications
- Interface translation between TTL/CMOS logic and RS-232 standards
- Multidrop RS-232 communication networks
- Portable diagnostic equipment requiring low-power serial connectivity
Procurement Notes
Verify that the specific ordering suffix matches the required thermal grade and package dimensions. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.
Selection Notes
Select this component when board space is limited due to the absence of external capacitors. Ensure the application requires four independent channels and benefits from individual enable controls for power management during idle periods.
Part Context
This part belongs to the MAX220–MAX249 family of +5V-powered RS-232 transceivers. These devices are designed for EIA/TIA-232E and V.28/V.24 interfaces where standard ±12V supplies are unavailable. The family offers various channel counts and packaging options to suit different system constraints.
Replacement Considerations
Compatible substitutes include other members of the MAX220–MAX249 series such as the MAX232 or MAX245, provided they match the required number of drivers and receivers and support the same operating temperature range.
