MAX3095EEE+T

Overview

The MAX3095EEE+T is a quad RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and supports data rates up to 10Mbps. The device features ±15kV ESD protection via the Human Body Model and IEC 1000-4-2 Air-Gap Discharge standards. Propagation delays are guaranteed within ±8ns, ensuring tight matching across production lots. It utilizes a 16-pin QSOP package with an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides robust electrostatic discharge (ESD) protection on all receiver inputs for harsh environments.
• Features complementary enable inputs that allow entry into a low-power shutdown mode with high-impedance outputs.
• Includes a fail-safe feature that guarantees a logic-high output when the differential input is open circuit.

Applications

• Telecommunications equipment
• Rugged RS-422/RS-485/RS-423 bus receivers
• Receivers for ESD-sensitive applications

Procurement Notes

Verify the specific suffix 'EEE+T' against official documentation to confirm the 16-pin QSOP package and tape-and-reel shipping format. Ensure the component meets lead-free/RoHS compliance requirements as indicated by the '+' designation in the ordering information section.

Selection Notes

Select this component for designs requiring quad RS-422/RS-485 reception with strict propagation delay matching. It serves as a pin-compatible upgrade to the industry-standard '26LS32. Verify that the system operates at +5V, as the MAX3096 variant is required for +3.3V applications.

Part Context

This part belongs to the MAX3095/MAX3096 series of rugged, low-power quad receivers. The MAX3095 specifically denotes the +5V operation variant, while the MAX3096 handles +3.3V supplies. Both share identical pinouts and functional characteristics except for supply voltage and slight propagation delay tolerances.

Replacement Considerations

The datasheet identifies the MAX3095 as a direct pin-compatible upgrade to the industry-standard '26LS32. Designers replacing legacy '26LS32 components can utilize the MAX3095EEE+T without modifying the board layout or external circuitry.

FAQ

How does the MAX3095 handle open-circuit inputs?

The device includes a fail-safe feature that guarantees a logic-high output if the receiver inputs are left open circuit, preventing undefined states during transmitter removal.

What is the maximum ESD protection rating?

Receiver inputs are protected to ±15kV using the Human Body Model and ±15kV using the IEC 1000-4-2 Air-Gap Discharge method.

Can the MAX3095 operate in a low-power state?

Yes, by setting the G input low and the G input high, the device enters a shutdown mode where outputs go high impedance and typical current draw drops below 1nA.
