Each transmitter output is 6kVIEC801-2, Contact Discharge protected against 15kV electrostatic discharge (ESD) 15kVIEC801-2, Air-Gap Discharge shocks. The inputs are TTL and CMOS compatible with Latchup Free, Even During an ESD Event minimal loading. The outputs feature internally controlled Low 85A Supply Current from I or I slew-rate limiting and current limiting. This device has a EE CC guaranteed 120kbps data rate. Power-supply current is Guaranteed 120kbps Data Rate less than 180A over a 4.5V to 13.2V supply voltage No External Capacitors Required for Slew-Rate range. Limiting The MAX1488E is pin compatible with the MC1488, Pin Compatible with MC1488, MC14C88, SN75188, MC14C88, SN75188, SN75C188, DS1488, and DS14C88. SN75C188, DS1488, and DS14C88 It is available in 14-pin plastic DIP and SO packages. Ordering Information Applications PC Motherboards PART TEMP.
