Supply Voltage (V CCA,VCCB) −0.5V to +7.0V DC Input Voltage (V I) @ OE, T/R −0.5V to V CCA +0.5V DC Input/Output Voltage (V I/O) @ A n −0.5V to V CCA +0.5V @ B n −0.5V to V CCB +0.5V DC Input Diode Current (I IK) @ OE, T/R ±20 mA DC Output Diode Current (I OK) ±50 mA DC Output Source or Sink Current (I O) ±50 mA DC V CC or Ground Current Per Output Pin (I CC or IGND) ±50 mA and Max Current ±200 mA Storage Temperature Range (T STG) −65˚C to +150˚C Recommended Operating Conditions (Note 2) Supply Voltage V CCA 4.5V to 5.5V V CCB 2.7V to 5.5V Input Voltage (V I) @ OE , T/R 0V to V CCA Input/Output Voltage (V I/O) @A n 0V to V CCA @B n 0V to V CCB Free Air Operating Temperature (T A) −55˚C to +125˚C Minimum Input Edge Rate ( ∆V/∆t) 8 ns/V V IN from 30% to 70% of VCC V CC @ 3V, 4.5V, 5.5V Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be op- erated at these limits. The parametric values defined in the Electrical Charac- teristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for ac- tual device operation. Note 2: The A port unused pins (inputs and I/O’s) must be held HIGH or LOW. They may not float.
