MAX3295AUT+T

MAX3295AUT+T is an automotive-grade differential transceiver from Maxim. It combines a driver and a receiver to connect a microcontroller to an RS-485/RS-422 multi-point bus.
Key points:
- Interfaces: A/B bus lines on the differential side; DI (driver input), RO (receiver output) on the MCU side; DE/RE or similar control pins to enable driver and receiver.
- Features: low-power operation, failsafe receiver (bus idle/shorts produce a defined logic level), built-in protection (ESD/overload), single-supply compatibility (typical 3.3V or 5V), suitable for harsh environments.
- Packaging: AUT indicates automotive-grade device with extended temperature range; +T denotes tape-and-reel packaging.
- Applications: automotive networks, industrial RS-485/RS-422 systems requiring durable, wide-temperature operation.
How to use: mount A/B to the differential bus, drive DI to send data, read RO for received data, and manage DE/RE to control transmission. Include proper line termination and biasing per the bus topology.

MAX3295AUT+T is a 5‑channel RS‑232 transceiver with an integrated charge pump. For direct cross‑refs, look for other 5‑port RS‑232 devices from major vendors. Common equivalents include TI’s 5‑port RS‑232 devices (SN75C3x/SN75C4x), Analog Devices ADM327x, STMicroelectronics ST323x/ST324x, NXP SP323x, and Microchip MCP23xx/MCP25xx (5‑channel variants). Verify channel count, supply voltage (3.3V/5V) and packaging for compatibility.

- Pin count: 16 pins (16-pin package).
- Function: Dual RS-232 transceiver (two drivers, two receivers) with on-chip charge-pump. Converts TTL/CMOS to RS-232 and RS-232 to TTL/CMOS; uses V+, V- and C1+/C1-, C2+/C2- for the charge pump. Pin names: T1IN, T2IN, T1OUT, T2OUT, R1IN, R2IN, R1OUT, R2OUT, VCC, GND, V+, V-, C1+, C1-, C2+, C2-.

- Manufacturer: Analog Devices (ADI). The MAX3295AUT+T was originally from Maxim Integrated, which ADI acquired in 2021; the product line is now under Analog Devices.
- What kind of company: A multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits.

MAX3295AUT+T is a differential RS-485/RS-422 transceiver (Automotive-grade). Typical applications:
- Industrial automation and PLC networks (multipoint, long distance)
- Data acquisition and remote telemetry over twisted-pair
- Building/home automation, energy meters, process control
- Automotive networks and in-vehicle instrumentation
- Instrumentation, test equipment, POS terminals and other robust serial links

The MAX3295AUT+T comes in an 8-pin SOIC (small-outline) package; it is RoHS-compliant (Pb-free).
