MAX3094EEUE+T

MAX3094EEUE+T is Maxim Integrated’s quad RS-422/RS-485 transceiver. It bundles four differential driver/receiver channels in one device, enabling a microcontroller to interface with up to four RS-485/RS-422 buses. Each channel has a DI input, RO output, and separate DE (driver enable) and RE (receiver enable) controls, allowing flexible topology (point-to-point or multi-drop). Typical features include failsafe receivers (predictable RO outputs when lines are idle or open), ESD protection, wide common‑mode tolerance, and operation from a common single-supply (commonly 3.3V or 5V). The +T suffix indicates Tape‑and‑Reel packaging; EEUE refers to the specific package/temperature/ RoHS options for this variant. Applications: industrial control, instrumentation, and building automation networks requiring multiple RS-485/RS-422 links in a single chip. For exact electrical specs, timing, pinout, and layout guidelines, consult the MAX3094EEUE+T datasheet and product page.

Here are the typical features of MAX3094EEUE+T (quad RS-485/RS-422 differential transceiver):
- Quad differential transceivers: four independent RS-485/RS-422 channels (driver and receiver per channel)
- Wide operating supply: single 3.3V–5V supply
- Fail-safe receivers: RO goes high when input is open, shorted, or idle
- Per-channel control: DI, DE, RE for individual channel enable/disable
- High bus protection: robust ESD protection on bus pins
- Wide bus common-mode range: supports long/ multipoint networks
- Data rate: up to ~20–25 Mbps per channel (typical)
- Low power: optimized current consumption for multi-channel use
- Temperature range: industrial (-40°C to +125°C)
- Packaging: RoHS-compliant, suitable for tape & reel (T) in a compact package
Note: exact specs may vary by revision/package; consult the latest datasheet for precise numbers.

Pin count: 28-pin package.
Function: Quad RS-422/RS-485 transceiver. It provides four differential drivers/receivers for multi-point serial communication, with per-channel control (driver/receiver enables) and the usual A/B bus pins on each channel (DI/RO, DE/RE typical per channel). Suitable for multi-drop differential data buses.

- Manufacturer: Maxim Integrated Products, now a part of Analog Devices, Inc.
- What kind of company: A semiconductor company that designs and markets analog and mixed-signal integrated circuits.
