MAX3094ECSE+T

Overview

The MAX3094ECSE+T is a quad RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3.0V to +3.6V supply, with typical operation at +3.3V. The device supports data rates up to 10Mbps and features ±15kV ESD protection on all inputs. Propagation delays are guaranteed within ±10ns of a predetermined value for device-to-device matching. It includes a low-power shutdown mode drawing less than 1nA and offers fail-safe logic-high outputs when inputs are open. The component is housed in a 16-pin Narrow SOIC package.

Feature Summary

• Integrated ±15kV ESD protection on receiver inputs compliant with IEC 1000-4-2 standards
• Guaranteed propagation-delay tolerance between devices for precise timing synchronization
• Low-power shutdown mode reduces supply current to less than 1nA
• Fail-safe feature ensures logic-high output during open-circuit input conditions

Applications

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

Procurement Notes

Verify the specific suffix 'CSE' corresponds to the commercial temperature range (0°C to +70°C) and the narrow SOIC package format. Confirm that the '+T' designation indicates tape-and-reel packaging as per manufacturer specifications. Ensure compatibility with existing board layouts requiring 16-pin surface-mount components.

Selection Notes

Select this component when a 3.3V supply voltage is required for RS-422 or RS-485 interfaces. Choose this part over the MAX3093E variant if lower power consumption at 3.3V is prioritized over 5V operation. Consider the guaranteed propagation delay matching for multi-channel applications requiring synchronized signal reception across different production lots.

Part Context

The MAX3094E series serves as a low-power upgrade to the industry-standard '34C86 receivers. It belongs to a family of rugged interface ICs designed for harsh environments. The ECSE variant specifically denotes the commercial temperature grade and narrow SOIC packaging, distinguishing it from extended temperature or TSSOP options within the same functional family.

Replacement Considerations

The MAX3094ECSE+T is a pin-compatible replacement for the SN75174 and DS26LS31C. Designers upgrading from these legacy parts should verify that the new ESD protection levels and supply voltage requirements align with the system design constraints.
