MAX3095CPE+

Overview

The MAX3095CPE+ is a quad RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and supports data rates up to 10Mbps. The device features ±15kV ESD protection on all inputs, compliant with IEC 1000-4-2 standards. Propagation delays are guaranteed within ±8ns for device-to-device matching. It includes complementary enable inputs for a 1nA low-power shutdown mode and provides fail-safe logic-high outputs when inputs are open circuit. The component utilizes a 16-pin Plastic DIP package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrated ±15kV electrostatic discharge protection on all receiver inputs
• Guaranteed propagation-delay tolerance between devices for minimal skewing
• Quarter-unit-load input impedance supporting up to 128 receivers on a bus
• Fail-safe feature ensuring logic-high output during open-circuit conditions

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm RoHS compliance status as indicated by the '+' suffix in the manufacturer's part numbering system. Ensure compatibility with existing PCB footprints for the 16-pin Plastic DIP configuration before procurement.

Selection Notes

Select this component for designs requiring robust ESD protection and precise timing matching across multiple receiver channels. Verify that the +5V supply voltage aligns with the system architecture, as the MAX3096 variant is required for +3.3V operation. Consider the 16-pin PDIP footprint constraints relative to available board space.

Part Context

The MAX3095CPE+ belongs to the MAX3095/MAX3096 family of rugged, low-power quad receivers. It serves as a pin-compatible, low-power upgrade to the industry-standard '26LS32. The 'C' designation indicates a commercial temperature range (0°C to +70°C), while the 'P' denotes the 16-pin Plastic DIP package.

Replacement Considerations

The MAX3096CPE+ is a compatible alternative for designs operating at +3.3V instead of +5V. Other pin-compatible options include the MAX3095EPE+ for extended industrial temperature ranges (-40°C to +85°C).

FAQ

How does the MAX3095CPE+ handle open-circuit inputs?

The device features a fail-safe mechanism that guarantees a logic-high output if the differential inputs are left open circuit.

What is the maximum data rate supported by this receiver?

The MAX3095CPE+ supports a maximum data rate of 10Mbps.

Can the MAX3095CPE+ be placed in a low-power state?

Yes, using complementary enable inputs allows the device to enter a shutdown mode where it draws typically less than 1nA of current.
