MAX1488EESD+

MAX1488EESD+ is a ±15kV ESD-protected, quad, low-power RS-232 line driver. It is designed for EIA/TIA-232, EIA/TIA-562, and CCITT V.28 communications in harsh environments. Each transmitter output is protected against ±15kV electrostatic discharge (ESD) shocks. The inputs are TTL and CMOS compatible with minimal loading. The outputs feature internally controlled slew-rate limiting and current limiting. It is pin-compatible with the MC1488, MC14C88, SN75188, SN75C188, DS1488, and DS14C88. Applications include PC motherboards, modems, interface data terminal equipment (DTE) with data circuit-terminating equipment (DCE), equipment meeting IEC1000-4-2 (formerly IEC801-2) or ±15kV ESD protection.

• Latch up free, even during an ESD event
• Low 85μA supply current from IEE or ICC
• Guaranteed 120kbps data rate
• No external capacitors required for slew-rate limiting
• Operating voltage range from 4.5 to 13.2V
• Output short-circuit current is ±20mA typ at output shorted to ground
• Propagation delay skew tPLH - tPHL is 0.25μs typ at VCC=4.5V, VEE=-4.5V, CL=50pF
• Output slew rate is 30V/μs max at CL=15pF to 2500pF, RL=3kohm to 7kohm, VCC=12V, TA=+25°C
• 14 SO package
• Temperature range from -40°C to +85°C
