________________General Description  
____________________________Features  
ESD Protection  
The MAX3093E/MAX3094E are rugged, low-power,  
quad, RS-422/RS-485 receivers featuring electrostatic  
discharge (ESD) protection for use in harsh environ-  
ments. All receiver inputs are protected to ±±5ꢀk using  
IEC ±000-4-2 Air-Gap Discharge, ±8ꢀk using IEC ±000-  
4-2 Contact Discharge, and ±±5ꢀk using the ꢁuman  
Body Model. The MAX3093E operates from a +5k sup-  
ply, while the MAX3094E operates from a +3.3k supply.  
Receiver propagation delays are guaranteed to within  
±8ns of a predetermined value, thereby ensuring  
device-to-device matching across production lots.

The devices feature a ±nA low-power shutdown mode  
in which the receiver outputs are high impedance.  
When active, these receivers have a fail-safe feature  
that guarantees a logic-high output if the input is open  
circuit. They also have a quarter-unit-load input imped-  
ance that allows ±28 receivers on a bus.

The MAX3093E/MAX3094E are pin-compatible, low-  
power upgrades to the industry-standard ’34C86. They  
are available in space-saving TSSOP, narrow SO, and  
PDIP pacꢀages.
