MAX3096CEE

Overview

The MAX3096CEE+ is a quad RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3.3V supply (range 3.135V to 3.6V) and supports data rates up to 10Mbps. The device features ±15kV ESD protection via Human Body Model, ±15kV IEC Air-Gap Discharge, and ±8kV IEC Contact Discharge. It includes complementary enable inputs for a 1nA low-power shutdown mode and guarantees propagation-delay matching within ±10ns across production lots. The component utilizes a 16-pin QSOP package with an operating temperature range of 0°C to +70°C.

Feature Summary

• Provides robust electrostatic discharge protection on all receiver inputs for harsh environments
• Features guaranteed device-to-device propagation delay tolerance for minimal signal skewing
• Offers a quarter-unit-load input impedance allowing up to 128 receivers on a bus
• Includes fail-safe functionality that guarantees a logic-high output when the input is open circuit

Applications

• Telecommunications equipment
• Rugged RS-422/RS-485/RS-423 bus receiver systems
• Receivers for ESD-sensitive applications
• Level translators

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Confirm RoHS compliance status as indicated by the '+' symbol in the part number. Ensure the design accommodates the required 3.3V supply voltage range and QSOP footprint dimensions before procurement.

Selection Notes

Select this component over the MAX3095 when a +3.3V supply is required instead of +5V. Consider the MAX3096EEE+ variant if operation below 0°C or above +70°C is necessary. Verify that the 10Mbps maximum data rate meets system requirements and that the 16-pin QSOP package fits the available PCB space constraints.

Part Context

The MAX3096CEE+ belongs to the MAX3095/MAX3096 family of rugged, low-power quad receivers. These devices serve as pin-compatible, low-power upgrades to the industry-standard '26LS32. While the MAX3095 operates at +5V, the MAX3096 is specifically designed for +3.3V applications, maintaining identical functional characteristics and interface compatibility.

Replacement Considerations

The MAX3095CEE+ serves as a direct pin-compatible alternative requiring a +5V supply instead of +3.3V. For extended temperature ranges, the MAX3096EEE+ provides the same electrical specifications but operates between -40°C and +85°C.

FAQ

How does the MAX3096 handle open-circuit inputs?

The device features a fail-safe mechanism that guarantees a logic-high output when the differential inputs are left open circuit.

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 on the same bus.

How is the low-power shutdown mode activated?

Shutdown is initiated by setting the active-high enable input (G) low and the active-low enable input (G) high, reducing supply current to typically less than 1nA.
