________________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.

♦ ±60Pin TSSOP
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.
