MAX3095CEE+

Overview

The MAX3095CEE+ 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. It utilizes a 16-pin QSOP package with an operating temperature range of 0°C to +70°C. Electrical characteristics include a typical supply current of 3.5mA, input hysteresis of 45mV, and propagation delays guaranteed within ±8ns between devices.

Feature Summary

• Provides robust electrostatic discharge protection for harsh environments
• Ensures precise timing through tightly matched propagation delays
• Supports high-density bus configurations with quarter-unit-load impedance
• Achieves ultra-low power consumption in shutdown mode

Applications

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

Procurement Notes

Verify the specific suffix 'CEE+' corresponds to the 16-pin QSOP package and commercial temperature range (0°C to +70°C). Confirm that the '+'' indicates lead-free/RoHS compliance as per the manufacturer's ordering information. Ensure compatibility with existing board layouts designed for the standard SO footprint due to the space-saving nature of the QSOP variant.

Selection Notes

Select this component when a low-power, quad receiver is required for RS-422 or RS-485 networks. It serves as a direct pin-compatible upgrade to the industry-standard '26LS32. Choose this part over the MAX3096 if the system design specifically requires a +5V supply voltage rather than the +3.3V operation supported by the MAX3096.

Part Context

This component belongs to the MAX3095/MAX3096 family of rugged, low-power quad receivers. The MAX3095 variant is distinguished by its requirement for a +5V supply, whereas the MAX3096 operates at +3.3V. Both share identical pinouts and functional capabilities, differing primarily in their supply voltage specifications and slight variations in propagation delay tolerances.

FAQ

How does the fail-safe feature function on the MAX3095?

The receiver inputs guarantee a logic-high output if the inputs are left open circuit. This ensures a defined state when the transmitter is removed from the bus or disabled.

What is the maximum number of receivers allowed on the bus?

Due to the quarter-unit-load input impedance (48kΩ), up to 128 MAX3095 receivers can be connected to a single 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. In this state, outputs go high impedance and supply current drops to approximately 1nA.
