MAX3095EEE

Overview

The MAX3095EEE+ 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 standards. Propagation delays are guaranteed within ±8ns for device-to-device matching. It includes complementary enable inputs for a 1nA low-power shutdown mode and offers fail-safe logic-high outputs on open circuits. The component is housed in a 16-pin QSOP package with an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides robust electrostatic discharge protection rated at ±15kV (Human Body Model) and ±8kV (IEC Contact Discharge) on all receiver inputs.
• Features tightly matched propagation delays with a guaranteed tolerance of ±8ns, ensuring minimal skew across multiple devices.
• Incorporates a quarter-unit-load input impedance, allowing up to 128 receivers to be connected on a single bus.
• Includes complementary active-high and active-low enable inputs that facilitate a low-power shutdown mode drawing less than 1nA.

Applications

• Telecommunications equipment requiring rugged interface components
• Rugged RS-422/RS-485/RS-423 bus receiver networks
• Receivers designed for environments sensitive to electrostatic discharge
• Level translator applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and temperature grade. Confirm RoHS compliance status based on the current datasheet revision. Ensure the selected variant matches the required supply voltage and environmental operating range for the intended application design.

Selection Notes

Select the MAX3095EEE+ when a single +5V supply is available and high-speed data transmission up to 10Mbps is required. This component is suitable for designs needing precise propagation delay matching between multiple ICs. Consider this part for systems requiring high noise immunity and the ability to support a large number of receivers on a shared bus line.

Part Context

The MAX3095EEE+ belongs to the MAX3095/MAX3096 family of quad receivers. It serves as a pin-compatible, low-power upgrade to the industry-standard '26LS32. While the MAX3095 operates on a +5V supply, its counterpart, the MAX3096, is designed for +3.3V operation. Both share similar functional characteristics but differ in their specific electrical thresholds and power requirements.

Replacement Considerations

The MAX3095EEE+ is functionally compatible with the '26LS32 standard. Other variants within the same family include the MAX3095EPE+ (PDIP) and MAX3095ESE+ (SOIC). Verify pin compatibility and thermal performance before substituting different package types.

FAQ

How does the MAX3095 handle open-circuit inputs?

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

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

Due to its quarter-unit-load input impedance, the MAX3095 allows up to 128 receivers to be connected on 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, placing the outputs in a high-impedance state.
