Overview
The MAX3189EUT is a single RS-232 transmitter manufactured by Analog Devices Inc./Maxim Integrated, designed for low-power applications. It operates within a supply voltage range of 4.5 V to 6 V, with a typical operating voltage of 5.4 V. The device supports data rates up to 1 Mb/s and features an ultra-low quiescent current consumption of 1 uA. Housed in a compact SOT-23-6 surface-mount package, it functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Ultra-low power consumption suitable for battery-operated systems
- Single-channel RS-232 transmission capability
- Compact SOT-23-6 surface-mount packaging
Applications
- Portable handheld devices requiring serial communication
- Battery-powered industrial instrumentation
- Low-power embedded control systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'EUT' matches design requirements. Check RoHS compliance documentation for regulatory adherence. Ensure storage conditions align with moisture sensitivity level specifications to prevent package damage during assembly.
Selection Notes
Select this component when only transmit functionality is required, as it lacks integrated receivers. Compare against the MAX3181EUK+T if receiver-only operation is needed instead. Evaluate the MAX3189EEUT+T variant if both transmit and receive channels are necessary for full-duplex communication. Verify that the SOT-23-6 footprint fits the PCB layout constraints.
Part Context
This part belongs to the MAX3189E series of low-power RS-232 transceivers. It represents a specialized subset focusing solely on transmission, distinguishing it from dual-channel counterparts like the MAX3189EEUT. The series targets applications where minimal power draw and small form factors are critical design drivers.
Replacement Considerations
The MAX3189EEUT+T serves as a functional substitute if dual-channel (transmit and receive) capability is acceptable. For receiver-only needs, the MAX3181EUK+T is an alternative. Direct pin-to-pin replacements for the single-transmitter configuration may be limited; verify electrical compatibility carefully.
