MAX3096ESE+T

Overview

The MAX3096ESE+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 on all inputs, ensuring reliability in harsh environments. It includes complementary enable inputs for a low-power shutdown mode with typical current draw of 1nA. The unit load input impedance allows up to 128 receivers on a bus. Propagation delays are guaranteed within ±10ns matching tolerance. It is housed in a 16-pin Narrow SO package and operates over an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides robust electrostatic discharge protection meeting IEC 1000-4-2 standards for air-gap and contact discharge scenarios.
• Features complementary active-high and active-low enable inputs that facilitate a deep low-power shutdown state.
• Offers guaranteed propagation-delay matching between devices to minimize signal skew across multiple lines.

Applications

• Telecommunications equipment requiring rugged bus receivers
• ESD-sensitive applications utilizing RS-422 or RS-485 protocols
• Level translation circuits in industrial communication systems

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with existing board layouts regarding the 16-pin Narrow SO footprint. Confirm that the +3.3V supply voltage aligns with system requirements before procurement.

Selection Notes

Select this component when designing systems requiring high ESD immunity and low power consumption. It serves as a direct pin-compatible upgrade to legacy '26LS32 receivers. Consider the ±10ns delay matching if precise timing synchronization between multiple receiver channels is critical for the application.

Part Context

This part belongs to the MAX3095/MAX3096 family of quad differential line receivers. While the MAX3095 operates at +5V, the MAX3096 is optimized for +3.3V operation. Both share identical pinouts and functional characteristics, differing primarily in supply voltage specifications and slight variations in propagation delay tolerances.

Replacement Considerations

The MAX3095EPE+ is a compatible alternative operating at +5V. Legacy equivalents include the SN75174 or DS26LS31C transmitters paired with standard '26LS32 receivers, though these lack the integrated ESD protection and low-power shutdown features found in the MAX3096 series.

FAQ

How does the MAX3096 achieve low-power shutdown?

The device enters shutdown mode when the active-high enable input (G) is low and the active-low enable input (G) is high. In this state, outputs go high impedance and supply current drops to approximately 1nA.

What is the fail-safe behavior of the MAX3096?

When the receiver inputs are open circuit, the device guarantees a logic-high output. This prevents undefined states if a transmitter is removed from the bus.

Can the MAX3096 support multiple receivers on a single bus?

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