These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. The package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions (see Notes 3 and 4) MIN TYP MAX UNIT VCC, BIAS VCC Supply voltage 3.15 3.3 3.45 V VI Input voltage Control inputs or A port VCC 5.5 V VI Input voltage B port VCC 5.5 V VIH High-level input voltage Control inputs or A port 2 V VIH High-level input voltage B port 0.5 VCC + 50 mV V VIL Low-level input voltage Control inputs or A port 0.8 V VIL Low-level input voltage B port 0.5 VCC − 50 mV V IIK Input clamp current −18 mA IOH High-level output current 3A port and Y output −12 mA IOH High-level output current B port −48 mA IOL Low-level output current 3A port and Y output 12 mA IOL Low-level output current B port 64 mA ∆t/∆v Input transition rise or fall rate Outputs enabled 10 ns/V ∆t/∆VCC Power-up ramp rate 20 µs/V TA Operating free-air temperature −40 85 °C NOTES: 3. All unused control inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004. 4. Proper connection sequence for use of the B-port I/O precharge feature is GND and BIAS VCC = 3.3 V first, I/O second, and VCC = 3.3 V last, because the BIAS VCC precharge circuitry is disabled when any VCC pin is connected. The control inputs can be connected anytime, but normally are connected during the I/O stage. If B-port precharge is not required, any connection sequence is acceptable, but generally, GND is connected first. |
