MAX1487ESA

The MAX1487ESA is designed as one kind of ±15kV ESD-protected, quad, low-power RS-232 line receiver that can be used in (1)PC motherboards; (2)modems; (3)interfacing data terminal equipment (DTE) with data circuit-terminating equipment (DCE); (4)equipment meeting IEC1000-4-2 (formerly IEC801-2) or ±15kV ESD protection. The input of this device is protected against ±15kV electrostatic discharge (ESD) shocks.

Features of the MAX1487ESA are:(1)enhanced ESD protection: ±15kV-human body model, ±8kV-IEC1000-4-2, contact discharge and  ±15kV-IEC1000-4-2, air-gap discharge; (2)latchup free during an ESD event; (3)low 350A supply current; (4)input hysteresis and time-domain filtering eliminate the need for external filtering; (5)stable input thresholds; (6)pin compatible with MC1489, MC14C89, SN75189, SN75C189, DS1489, and DS14C89.

The absolute maximum ratings of the MAX1487ESA can be summarized as:(1)Supply Voltage (VCC): +7 V;(2)Input Voltage (VIN): ±30 V;(3)Output Short-Circuit Current (Shorted to GND or VCC): Self Limiting;(4)Continuous Power Dissipation (TA = +70°C) Plastic DIP: 800 mW;(5)Continuous Power Dissipation (TA = +70°C) SO: 695 mW;(6)Lead Temperature (soldering, 10sec): +300°C;(7)Storage Temperature Range: -65°C to +160°C;(8)Lead Temperature (soldering, 10sec): +300°C.

The electrical characteristics of the MAX1487ESA can be summarized as:(1)Output Voltage Low: 0.17 to 0.4 V;(2)Supply Current: 260 to 600 A;(3)Input Voltage Range: -25 to 25 V;(4)Input Voltage High: 1.60 to 2.60 V;(5)Input Voltage Low: 0.75 to 1.30 V;(6)Input Hysteresis: 1.11 V;(7)Input Resistance: 3.0 to 7.0 k;(8)Output Propagation Delay, Low to High: 1.38 to 4.0 s;(9)Output Propagation Delay, High to Low: 1.45 to 4.0 s.
