MAX3095

19-0498; Rev 0; 3/98 ±15kV ESD-Protected, 10Mbps, 3V/5V, Quad RS-422/RS-485 Receivers ________________General Description The MAX3095/MAX3096 are rugged, low-power, quad, RS-422/RS-485 receivers with electrostatic discharge (ESD) protection for use in harsh environments. All receiver inputs are protected to ±15kV using IEC 10004-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model. The MAX3095 operates from a +5V supply, while the MAX3096 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. Complementary enable inputs can be used to place the devices in 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 feature a quarter-unit-load input impedance that allows 128 receivers on a bus. The MAX3095/MAX3096 are pin-compatible, low-power upgrades to the industry-standard ’26LS32. They are available in a space-saving QSOP package. ____________________________Features o ESD Protection: ±15kV—IEC 1000-4-2, Air-Gap Discharge ±8kV—IEC 1000-4-2, Contact Discharge ±15kV—Human Body Model o Guaranteed Propagation-Delay Tolerance Between All ICs: ±8ns (MAX3095) ±10ns (MAX3096) o Single +3V Operation (MAX3096) Single +5V Operation (MAX3095) o 16-Pin QSOP (8-pin S...
