MAX3096ESE

Overview

The MAX3096ESE is a quad RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +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. Propagation delays are guaranteed within ±10ns tolerance, ensuring 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 utilizes a 16-pin Narrow SO package.

Feature Summary

• Provides robust electrostatic discharge protection for harsh environments
• Ensures precise timing with guaranteed propagation-delay matching across production lots
• Enables ultra-low power consumption through a dedicated shutdown mode

Applications

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

Procurement Notes

Verify that the specific part number corresponds to the industrial temperature range of -40°C to +85°C. Confirm the package type matches the required 16-pin Narrow SO footprint. Ensure the design accommodates the +3.3V supply voltage requirement distinct from the +5V MAX3095 variant. Check for lead-free/RoHS compliance status indicated by the suffix.

Selection Notes

Select this component when a low-voltage +3.3V operation is required for RS-422/RS-485 interfaces. Choose the MAX3096 over the MAX3095 specifically for its lower supply voltage compatibility. Consider this device for systems requiring high ESD immunity and tight propagation delay matching between multiple receiver units on the same bus.

Part Context

The MAX3096 serves as a low-power, pin-compatible upgrade to the industry-standard '26LS32 quad differential line receiver. It belongs to the MAX3095/MAX3096 family, distinguished primarily by its operating supply voltage. While the MAX3095 operates at +5V, the MAX3096 is optimized for +3.3V systems, maintaining identical functionality and pinout for easy migration.

FAQ

What is the input impedance of the MAX3096?

The MAX3096 features a quarter-unit-load input impedance (48 kΩ), allowing up to 128 receivers to be connected on a single bus.

How does the fail-safe feature operate?

When the receiver inputs are left open circuit, the device guarantees a logic-high output state.

What is the propagation delay tolerance?

Receiver propagation delays are guaranteed to within ±10ns of a predetermined value, ensuring device-to-device matching across production lots.
