dual eia-423/eia-232d line driver the mc3488a dual is singleended line driver has been designed to satisfy the requirements of eia standards eia423 and eia232d, as well as ccitt x.26, x.28 and federal standard fids1030. it is suitable for use where signal wave shaping is desired and the output load resistance is greater than 450 ohms. output slew rates are adjustable from 1.0 m s to 100 m s by a single external resistor. output level and slew rate are insensitive to power supply variations. input undershoot diodes limit transients below ground and output current limiting is provided in both output states. the mc3488a has a standard 1.5 v input logic threshold for ttl or nmos compatibility. ? pnp buffered inputs to minimize input loading ? short circuit protection ? adjustable slew rate limiting ? mc3488a equivalent to 9636a ? output levels and slew rates are insensitive to power supply voltages ? no external blocking diode required for v ee supply ? second source m a9636a simplified application wave shape control ttl logic rs-423 interface mc3488a driver mc3486 three-state receiver on semiconductor ? semiconductor components industries, llc, 2001 august, 2001 rev. 3 1 publication order number: mc3488a/d device operating temperature range package mc3488a semiconductor technical data dual eia423/eia232d driver ordering information mc3488ap1 mc3488ad t a = 0 to +70 c plastic dip so8 p1 suffix plastic package case 626 d suffix plastic package case 751 (so8) pin connections 5 6 8 7 4 3 1 2 input b input a gnd wave shape output a v cc output b v ee
