MAX3373EEKA+T

MAX3373EEKA+T is a Maxim RS-485/RS-422 transceiver. It provides a differential 2‑wire bus (A, B) with DI (data in) and RO (receiver out). It supports half‑duplex operation for multi‑drop networks and has independent DE (driver enable) and /RE (receiver enable) pins for controllable power usage and bus arbitration. A fail‑safe receiver ensures RO goes high when the bus is idle, open, or shorted. EEKA indicates a specific package/temperature option; +T means tape‑and‑reel packaging. Typical operation uses a 3.0–5.5 V supply with data rates up to tens of Mbps. Features often include ESD protection and low quiescent current. Applications: industrial automation, building controls, sensor networks, and microcontroller interfaces to RS‑485/RS‑422. For exact electrical specs, pinout, and packaging, refer to the MAX3373 data sheet and ordering guide.

Here are concise features of MAX3373EEKA+T:
- High-speed, low-power RS-422/RS-485 half-duplex transceiver
- Driver/receiver on A and B lines; two-wire bus
- 3-state outputs with separate DE (driver enable) and RE (receiver enable)
- Fail-safe receiver: RO goes high for open, shorted, or idle bus
- Wide supply range (typical 3V–5V) with low quiescent current
- ESD and bus-protection on A/B lines
- Industrial temperature variant (-40°C to +85°C)
- Small 8-pin package (EEKA) with Tape & Reel option (+T)
- Fully differential signaling and bus-capable for multi-node networks
- RS-485/RS-422 compliant interfaces

Pin count: 8 pins.
Function: One-channel differential transceiver (RS-485/RS-422). It provides both a driver and a receiver and is used for differential serial communication. Typical pins include DI (data in), RO (data out), DE (/enable for driver), \RE (receiver enable), A and B (bus lines), Vcc, and GND. The “+T” suffix denotes Tape-and-Reel packaging.

- Manufacturer: Maxim Integrated (now part of Analog Devices).
- What kind of company: A global fabless semiconductor company that designs and markets analog, mixed-signal, and digital integrated circuits, outsourcing manufacturing to external foundries.

Typical applications for MAX3373E (MAX3373EEKA+T) include:
- Industrial automation and process control (PLCs, remote I/O, motor networks)
- Building automation (HVAC, lighting, security)
- Data acquisition and instrumentation (multi-node sensors, remote telemetry)
- RS-485/RS-422 differential networks (industrial daisy-chain, multi-drop)
- Smart metering and energy-management systems
- Point-of-sale terminals and telecom infrastructure
- Long-distance sensor networks and remote monitoring
These transceivers are used where robust differential signaling, long cable runs, and noisy environments are common.

MAX3373EEKA+T is in an 8-pin SOIC (D-8) package. It is lead-free (E) and available in Tape & Reel ( +T ) shipping.
