MAX13442EASA

MAX13442EASA is a Maxim Integrated (now Analog Devices) analog-switch/multiplexer IC. It’s designed to route or switch multiple analog signals with low distortion, controlled by a small digital interface. The device typically provides several 2:1 or similar multiplexing paths in a compact package, making it useful for signal routing in tight PCB layouts.
Key points
- Low on-resistance and high off-isolation for clean signal paths
- Fast switching with suitable control timing
- Wide supply range (typical 2.7–5.5 V) and protections such as ESD and break-before-make
- EASA suffix denotes a specific packaging/grade variant (industrial/automotive grade in a defined package)
Common applications
- Audio/video signal routing
- Instrumentation and data-acquisition front-ends
- Portable electronics and telecom sensing
For exact pinout, RDS(on), switch times, and package details, consult the official MAX13442EASA datasheet. If you share your application requirements, I can tailor the summary to those specs.

MAX13442EASA is a quad RS-485/RS-422 transceiver. There isn’t a direct 1:1 cross. Closest equivalents are quad RS-485/RS-422 transceivers from other vendors:
- TI: SN65HVD42 and SN65HVD41
- NXP: PCA82C254/PCA82C255
- Analog Devices: ADM2483/ADM2485 (and related quad/isolation variants)
For exact specs (voltage, data rate, isolation), consult datasheets and use a cross-reference from suppliers or distributors.

Pin count: 28 pins.
Function: Quad RS-485/RS-422 transceiver (four differential channels) with individual driver/receiver sections, enable controls, and 3-state outputs for multi-drop differential bus communication.

Manufacturer: Analog Devices, Inc. (ADI) — formerly Maxim Integrated (the MAX prefix). ADI is a global semiconductor company that designs and manufactures analog and mixed-signal integrated circuits.

Applications: 4-channel isolated RS-485/RS-422 transceiver for industrial automation and control (PLCs, motor drives, robotics) in multi-point, long-distance networks; remote telemetry and data acquisition; process instrumentation requiring galvanic isolation; smart grid and energy metering equipment; building automation (HVAC, lighting, security) networks; systems needing strong noise immunity and safety isolation between hostile environments and host electronics.

The MAX13442EASA is in a 20-pin TSSOP (Thin Shrink Small Outline Package).
