MAX3096EEE+T

Overview

The MAX3096EEE+T is a quad RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3.3V supply and supports data rates up to 10Mbps. The device features ±15kV ESD protection via the Human Body Model and IEC 1000-4-2 standards. It includes complementary enable inputs for a 1nA low-power shutdown mode and guarantees propagation-delay matching within ±10ns. The unit utilizes a 16-pin QSOP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides robust electrostatic discharge protection on all receiver inputs for harsh environments
• Ensures precise timing synchronization through guaranteed device-to-device propagation-delay matching
• Supports high bus density with quarter-unit-load input impedance allowing up to 128 receivers
• Features fail-safe logic that guarantees a logic-high output when differential inputs are open circuit

Applications

• Telecommunications equipment requiring rugged bus receivers
• ESD-sensitive industrial applications needing enhanced input protection
• Level translation between different voltage domains in RS-422/RS-485 networks

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type, temperature grade, and lead-free status. Confirm compatibility with system power rails and signal integrity requirements before procurement. Ensure the component meets necessary environmental compliance standards for the intended deployment region.

Selection Notes

Select this component when designing systems requiring low-voltage operation at 3.3V with high-speed data reception. Consider its tight propagation-delay tolerance for multi-drop bus architectures where skew must be minimized. Evaluate the need for integrated ESD protection to reduce external component count and board space.

Part Context

This part belongs to the MAX3095/MAX3096 family of low-power, quad RS-422/RS-485 receivers. It serves as a pin-compatible, low-power upgrade to the industry-standard '26LS32 devices. While the MAX3095 variant operates at +5V, the MAX3096 is specifically optimized for +3.3V supplies, maintaining identical functionality and pinout.

Replacement Considerations

The MAX3095 series is a direct pin-compatible alternative but requires a +5V supply instead of +3.3V. Other legacy '26LS32 devices may fit physically but lack the specified ESD protection levels and low-power shutdown capabilities.

FAQ

How does the MAX3096 achieve low-power shutdown?

The device enters a 1nA shutdown mode when the active-high enable (G) is taken low and the active-low enable (G) is taken high, placing all outputs in a high-impedance state.

What is the maximum number of receivers supported on a single bus?

Due to its quarter-unit-load input impedance, the MAX3096 allows up to 128 receivers to be connected to a single RS-485 bus.

Does the device include fail-safe features?

Yes, the receivers guarantee a logic-high output if the differential inputs are left open-circuited, preventing undefined states during transmitter disconnection.
