3 / 5 page Philips Semiconductors Linear Products Product specification MC145406 EIA-232-D/V.28 driver/receiver August 31, 1994 469 ABSOLUTE MAXIMUM RATINGS SYMBOL PARAMETER RATING UNITS VCC Supply voltage -0.5 to +6.0 V VDD Supply voltage -0.5 to +13.5 V VSS Supply voltage +0.5 to -13.5 V VIR Input voltage range RX1-3 inputs DI1-3 inputs (VSS - 15) to (VDD + 15) -0.5 to (VCC + 0.5) V DC current per pin +100 mA PD Power dissipation (package) 1.0 W TA Operating temperature range 0 to +70 °C TSTG Storage temperature range -65 to +150 °C θJA Thermal impedance N package D package 80 105 °C/W NOTE: This device contains protection circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it is advised that normal precautions be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit. For proper operation, it is recommended that the voltages at the DI and DO pins be constrained to the range GND < VDI < VDD and GND < VDO < VCC. Also, the voltage at the RX pin should be constrained to +25V, and TX should be constrained to VSS < VTX1-3 < VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., GND or VCC for DI, and VSS or VDD for RX). DC ELECTRICAL CHARACTERISTICS Typical values are at TA = 0 to 70°C; GND = 0V, unless otherwise specified.

This is the range of input voltages as specified by EIA-232-D to cause a receiver to be in the high or low logic state. |
