Overview
The MAX3093ECPE is a quad RS-422/RS-485 receiver in a 16-pin Plastic DIP package. It operates from a +5V supply with a maximum data rate of 10Mbps. The device features ±15kV ESD protection and a low-power shutdown mode drawing 1nA. Operating temperature range is 0°C to +70°C. Propagation delay tolerance is ±8ns, allowing up to 128 receivers on the bus.
Feature Summary
- Integrated ±15kV electrostatic discharge protection for harsh environments
- Guaranteed propagation-delay matching between devices
- Quarter-unit-load input impedance supporting high node counts
- Fail-safe feature ensuring logic-high output during open circuit
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 'CPE' corresponds to the 0°C to +70°C temperature range and 16-pin Plastic DIP package configuration. Confirm that the component is sourced directly from Analog Devices or authorized distributors to ensure authenticity and traceability.
Selection Notes
Select this part when a 5V supply is required alongside robust ESD protection and precise timing matching. The Plastic DIP package is suitable for through-hole mounting. Ensure the design accommodates the 128-receiver bus capacity provided by the quarter-unit-load input impedance.
Part Context
This component belongs to the MAX3093E/MAX3094E family of low-power quad receivers. It serves as a pin-compatible upgrade to the industry-standard '34C86. The 'E' suffix indicates extended temperature capability, while 'C' denotes commercial range.
Replacement Considerations
The MAX3093ECPE is a direct pin-compatible replacement for the SN75176 or similar legacy RS-485 receivers. Verify voltage levels and package dimensions before substitution.
FAQ
What is the input impedance of the MAX3093ECPE?
The device presents a quarter-unit-load input impedance (48kΩ), allowing up to 128 receivers on a single bus.
How does the fail-safe feature work?
The receiver inputs guarantee a logic-high output if the input is left open circuit, preventing undefined states when transmitters are disabled.
What is the power consumption in shutdown mode?
In low-power shutdown mode, the typical supply current is 1nA, with all outputs in a high-impedance state.
