MAX3096CSE+

Overview

The MAX3096CSE+ 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 matching within ±10ns. The unit load input impedance allows up to 128 receivers on a bus, and it incorporates a fail-safe feature that ensures a logic-high output when inputs are open circuit.

Feature Summary

• Integrated ±15kV electrostatic discharge (ESD) protection on all receiver inputs
• Guaranteed device-to-device propagation-delay matching for minimal signal skew
• Quarter-unit-load input impedance enabling high node density on communication buses
• Complementary enable inputs supporting ultra-low power shutdown operation

Applications

• Telecommunications equipment requiring robust bus reception
• Rugged RS-422/RS-485/RS-423 bus receiver implementations
• Receivers designed for environments sensitive to electrostatic discharge
• Level translation applications between different voltage domains

Procurement Notes

Verify the specific package code S16+5 corresponds to the 16-pin Narrow SOIC format required for your PCB layout. Confirm the 'C' suffix indicates the commercial temperature range of 0°C to +70°C matches your operational environment. Ensure the + suffix denotes lead-free/RoHS compliance if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component over the MAX3095 when a +3.3V supply rail is available, as the MAX3095 requires a +5V supply. Consider the MAX3096 for designs prioritizing lower operating current compared to standard legacy receivers. Verify that the 10Mbps maximum data rate satisfies your system's throughput requirements before finalizing the design.

Part Context

This part belongs to the MAX3095/MAX3096 family, which serves as a low-power upgrade to the industry-standard '26LS32 quad differential line receivers. While the MAX3095 handles +5V systems, the MAX3096 is specifically optimized for +3.3V operation. Both devices share identical pinouts and functional characteristics, differing primarily in their supply voltage specifications and propagation delay tolerances.

Replacement Considerations

The MAX3095CSE+ is a direct pin-compatible replacement if the system can accommodate a +5V supply instead of +3.3V. Legacy '26LS32 devices may be replaced, though they lack the integrated ESD protection and guaranteed propagation-delay matching found in the MAX3096 series.
