MAX3094ECPE+

Overview

The MAX3094ECPE+ is a quad RS-422/RS-485 receiver operating from a single +3.3V supply. It supports data rates up to 10Mbps with guaranteed propagation-delay matching of ±10ns across production lots. The device features ±15kV ESD protection via Human Body Model and IEC 1000-4-2 standards. It includes a low-power shutdown mode drawing typically 1nA, fail-safe logic-high outputs for open inputs, and a quarter-unit-load input impedance allowing up to 128 receivers on the bus. It is housed in a 16-pin Plastic DIP package.

Feature Summary

• Integrated ±15kV electrostatic discharge protection on all receiver inputs
• Guaranteed propagation-delay matching between devices within ±10ns tolerance
• Quarter-unit-load input impedance enabling high node density on communication buses
• Fail-safe feature ensuring logic-high output when differential inputs are open

Applications

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

Procurement Notes

Verify the specific ordering suffix 'CPE+' corresponds to the commercial temperature range (0°C to +70°C) and 16-pin Plastic DIP package configuration. Confirm that the component meets RoHS compliance requirements as indicated by the '+' designation. Ensure the datasheet revision matches the intended design specifications before finalizing procurement orders.

Selection Notes

Select this component when a low-power, rugged receiver is required for harsh environments. The MAX3094E variant is specifically designed for +3.3V systems, distinguishing it from the +5V MAX3093E. Consider the 16-pin PDIP package for through-hole mounting needs or legacy board designs requiring pin-compatible upgrades to the industry-standard '34C86.

Part Context

This part belongs to the MAX3093E/MAX3094E family of low-power quad receivers. The MAX3094E series is optimized for 3.3V operation, whereas the MAX3093E operates at 5V. Both families share identical pinouts and functional characteristics, differing primarily in supply voltage requirements and propagation delay tolerances.

Replacement Considerations

The MAX3094ECPE+ serves as a pin-compatible, low-power upgrade to the industry-standard SN75176 or similar '34C86 variants. Verify that replacement candidates support the same 10Mbps data rate and 3.3V supply voltage while maintaining comparable ESD protection levels.
