Order this document by MC3488A/D 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 µs to 100 µs 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 • • • • • • DUAL EIA–423/EIA–232D DRIVER SEMICONDUCTOR TECHNICAL DATA P1 SUFFIX PLASTIC PACKAGE CASE 626 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 D SUFFIX PLASTIC PACKAGE CASE 751 (SO–8) Second Source µA9636A PIN CONNECTIONS Wave 1 Shape 8 VCC Input A 2 7 Output A Input B 3 6 Output B Gnd 4 5 VEE ORDERING INFORMATION Device MC3488AP1 MC3488AD Operating Temperature Range TA = 0 to +70°C Package Plastic DIP SO–8 Simplified Application Wave Shape Control MC3488A Driver MC3486 Three–State Receiver RS–423 Interface TTL Logic Motorola, Inc. 1996 MOTOROLA ANALOG IC DEVICE DATA Rev 2 1 MC3488A MAXIMUM RATINGS (Note 1) Rating Symbol Value Unit VCC VEE + 15 – 15 V IO + IO – + 150 – 150 Operating Ambient Temperature TA 0 to + 70 °C Junction Temperature Range TJ 150 °C Storage Temperature Range Tstg – 65 to + 150 °C Power Supply Voltages Output Current Source Sink mA RECOMMENDED OPERATING CONDITIONS Characteristic Power Supply Voltages Operating Temperature Range Wave Shaping Resistor Symbol Min Typ Max Unit VCC VEE 10.8 – 13.2 12 – 12 13.2 – 10.8 V TA 0 25 70 °C RWS 10 – 1000 kΩ TARGET ELECTRICAL CHARACTERISTICS (Unless otherwise noted, specifications apply over recommended operating conditions) Symbol Min Typ Max Unit Input Voltage – Low Logic State VIL – – 0.8 V Input Voltage – High Logic State VIH 2.0 – – V Input Current – Low Logic State (VIL = 0.4 V) IIL – 80 – – µA IIH1 IIH2 – – – – 10 100 Input Clamp Diode Voltage (IIK = – 15 mA) VIK – 1.5 – – Output Voltage – Low Logic State (RL = ∞) EIA–423 (RL= 3.0 kΩ) EIA–232D (RL= 450 Ω) EIA–423 VOL – 6.0 – 6.0 – 6.0 – – – – 5.0 – 5.0 – 4.0 Output Voltage – High Logic State (RL = ∞) EIA–423 (RL.= 3.0 kΩ) EIA–232D (RL = 450 Ω) EIA–423 VOH 5.0 5.0 4.0 – – – 6.0 6.0 6.0 RO – 25 50 IOSH IOSL – 150 + 15 – – – 15 + 150 Output Leakage Current (Note 3) (VCC = VEE = 0 V, – 6.0 V Vo p p 6.0 V) Iox – 100 – 100 µA Power Supply Currents (RW = 100 kΩ, RL = ∞, VIL p Vin p VIH) ICC IEE – – 18 – – + 18 – mA Characteristic Input Current – High Logic State (VIH = 2.4 V) (VIH = 5.5 V) Output Resistance (RL 450 Ω) q Output Short–Circuit Current (Note 2) (Vin = Vout = 0 V) (Vin = VIH(Min), Vout = 0 V) µA V V V Ω mA NOTES: 1.
