MAX3096CSE+T

Overview

The MAX3096CSE+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, compliant with IEC 1000-4-2 standards. It includes complementary enable inputs for a low-power shutdown mode drawing typically 1nA. The unit load input impedance allows up to 128 receivers on a bus. It is housed in a 16-pin Narrow SO package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrated ±15kV electrostatic discharge (ESD) protection on all receiver inputs
• Complementary enable inputs support a low-power shutdown mode
• Fail-safe feature guarantees a logic-high output when the input is open circuit
• Quarter-unit-load input impedance enables connection of up to 128 receivers

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm lead-free status and RoHS compliance requirements against project specifications. Ensure the narrow SOIC footprint aligns with existing PCB land patterns. Validate that the component revision corresponds to the intended design implementation.

Selection Notes

Select this part when a low-power, high-speed RS-422/RS-485 receiver is needed for 3.3V systems. It serves as a pin-compatible upgrade to the industry-standard '26LS32. Consider its tight propagation-delay matching for multi-line synchronization. Verify that the 10Mbps maximum data rate meets system timing requirements.

Part Context

This component belongs to the MAX3095/MAX3096 family of rugged, low-power quad receivers. While the MAX3095 operates at +5V, the MAX3096 is optimized for +3.3V supplies. Both share identical pinouts and functional characteristics, differing primarily in their supply voltage requirements and specific propagation delay tolerances.

Replacement Considerations

The MAX3095 is a direct pin-compatible alternative designed for +5V operation. Other quad receivers in the same family may offer different supply voltages or packaging options. Verify electrical compatibility before substituting any other RS-422/RS-485 receiver ICs.

FAQ

How does the MAX3096 achieve low power consumption?

It utilizes complementary enable inputs to enter a shutdown mode where outputs go high impedance and current draw drops to typically 1nA.

What is the fail-safe behavior of the MAX3096?

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

Can multiple MAX3096 devices be used on the same bus?

Yes, due to their quarter-unit-load input impedance, up to 128 receivers can be connected to a single bus.
