Low-Power Quad RS-422/RS-485 Receivers
________________General Description
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 ±15kV using
IEC 1000-4-2 Air-Gap Discharge, ±8kV using IEC 1000-
4-2 Contact Discharge, and ±15kV using the Human
Body Model. The MAX3093E operates from a +5V sup-
ply, while the MAX3094E operates from a +3.3V 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 1nA 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 128 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 packages.
