MAX3096CPE+

Overview

The MAX3096CPE+ 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 via the Human Body Model and IEC 1000-4-2 standards. It includes complementary enable inputs for a 1nA low-power shutdown mode and guarantees propagation-delay tolerance within ±10ns. The component utilizes a 16-pin Plastic DIP package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Provides robust electrostatic discharge protection on all receiver inputs, ensuring reliable operation in harsh environments without external components.
• Features guaranteed propagation-delay matching between devices to minimize skewing across multiple data lines and production lots.
• Incorporates a fail-safe mechanism that ensures a logic-high output when receiver inputs are left open circuit.

Applications

• Telecommunications equipment requiring rugged bus receivers
• ESD-sensitive applications needing integrated input protection
• Level translation circuits utilizing RS-422 or RS-485 protocols

Procurement Notes

Verify the specific suffix 'CPE+' corresponds to the required commercial temperature range and lead-free packaging status. Confirm the 16-pin Plastic DIP footprint matches the target PCB layout. Ensure the design accommodates the +3.3V supply voltage requirements specified for the MAX3096 variant rather than the MAX3095.

Selection Notes

Select this component when a low-power, quad receiver with high ESD immunity is required for RS-422/RS-485 networks. It serves as a pin-compatible upgrade to the industry-standard '26LS32. Choose the MAX3096 specifically over the MAX3095 if the system operates exclusively on a +3.3V rail, as the latter requires a +5V supply.

Part Context

This part belongs to the MAX3095/MAX3096 family of rugged, low-power quad receivers designed for harsh environments. The MAX3096 variant is distinguished by its +3.3V operation, whereas the MAX3095 operates at +5V. Both share identical pinouts and functional characteristics, differing primarily in supply voltage specifications and propagation delay tolerances.

Replacement Considerations

The MAX3095CPE+ is a direct pin-compatible alternative if the application can support a +5V supply. Other package variants such as MAX3096CSE+ (Narrow SO) or MAX3096CEE+ (QSOP) offer space-saving options while maintaining electrical compatibility.

FAQ

How does the MAX3096 handle open-circuit inputs?

The device incorporates a fail-safe feature that guarantees a logic-high output when the differential inputs are open circuit, preventing undefined states during transmitter removal.

What is the maximum ESD protection rating for the inputs?

All receiver inputs are protected to ±15kV using the Human Body Model and ±15kV using the IEC 1000-4-2 Air-Gap Discharge method.

Can multiple MAX3096 devices be used on the same bus?

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