| Order this document by MC3488A/D Dual EIA-423/EIA-232D Line Driver The MC3488A dual is single-ended line driver has been designed to satisfy the requirements of EIA standards EIA-423 and EIA-232D, 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 s to 100 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 MC3488A DUAL EIA-423/EIA-232D DRIVER SEMICONDUCTOR TECHNICAL DATA * * * * * * 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 VEE Supply Second Source A9636A D SUFFIX PLASTIC PACKAGE CASE 751 (SO-8) P1 SUFFIX PLASTIC PACKAGE CASE 626 PIN CONNECTIONS Wave 1 Shape Input A 2 Input B 3 Gnd 4 8 7 6 5 VCC Output A Output B VEE ORDERING INFORMATION Device MC3488AP1 MC3488AD Operating Temperature Range TA = 0 to +70C Package Plastic DIP SO-8 Simplified Application Wave Shape Control MC3488A Driver RS-423 Interface MC3486 Three-State Receiver TTL Logic (c) Motorola, Inc. 1996 Rev 2 MOTOROLA ANALOG IC DEVICE DATA 1 MC3488A MAXIMUM RATINGS (Note 1) Rating Power Supply Voltages Output Current Source Sink Operating Ambient Temperature Junction Temperature Range Storage Temperature Range Symbol VCC VEE IO + IO - TA TJ Tstg Value + 15 - 15 + 150 - 150 0 to + 70 150 - 65 to + 150 C C C Unit V mA RECOMMENDED OPERATING CONDITIONS Characteristic Power Supply Voltages Operating Temperature Range Wave Shaping Resistor Symbol VCC VEE TA RWS Min 10.8 - 13.2 0 10 Typ 12 - 12 25 - Max 13.2 - 10.8 70 1000 Unit V C k TARGET ELECTRICAL CHARACTERISTICS (Unless otherwise noted, specifications apply over recommended operating conditions) Characteristic Input Voltage - Low Logic State Input Voltage - High Logic State Input Current - Low Logic State (VIL = 0.4 V) Input Current - High Logic State (VIH = 2.4 V) (VIH = 5.5 V) Input Clamp Diode Voltage (IIK = - 15 mA) Output Voltage - Low Logic State (RL = ) EIA-423 (RL= 3.0 k) EIA-232D (RL= 450 ) EIA-423 Output Voltage - High Logic State (RL = ) EIA-423 (RL.= 3.0 k) EIA-232D (RL = 450 ) EIA-423 Output Resistance (RL 450 ) Symbol VIL VIH IIL Min - 2.0 - 80 Typ - - - Max 0.8 - - Unit V V A A IIH1 IIH2 VIK VOL - 6.0 - 6.0 - 6.0 VOH 5.0 5.0 4.0 RO - - - - 25 6.0 6.0 6.0 50 mA IOSH IOSL Iox ICC IEE - 150 + 15 - 100 - - 18 - - - - - - 15 + 150 100 + 18 - A mA - - - - 5.0 - 5.0 - 4.0 V - - - 1.5 - - - 10 100 - V V q Output Short-Circuit Current (Note 2) (Vin = Vout = 0 V) (Vin = VIH(Min), Vout = 0 V) Output Leakage Current (Note 3) (VCC = VEE = 0 V, - 6.0 V Vo Power Supply Currents (RW = 100 k, RL = , VIL p p 6.0 V) p Vin p VIH) NOTES: 1.
