7 / 31 page  SN74VMEH22501 www.ti.com SCES357F – JULY 2001 – REVISED FEBRUARY 2010 Absolute Maximum Ratings (1) over operating free-air temperature range (unless otherwise noted) MIN MAX UNIT VCC, Supply voltage range –0.5 4.6 V BIAS VCC VI Input voltage range(2) –0.5 7 V VO Voltage range applied to any output in the high-impedance or power-off state(2) –0.5 7 V 3A port or Y output –0.5 VCC + 0.5 Voltage range applied to any output in the high or low VO V state(2) B port –0.5 4.6 3A port or Y output 50 IO Output current in the low state mA B port 100 3A port or Y output –50 IO Output current in the high state mA B port –100 IIK Input clamp current VI < 0 –50 mA IOK Output clamp current VO < 0 or VO > VCC, B port –50 mA DGG package 70 qJA Package thermal impedance(3) DGV package 58 °C/W GQL/ZQL package 42 Tstg Storage temperature range –65 150 °C (1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. 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. (2) The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. (3) The package thermal impedance is calculated in accordance with JESD 51-7. Recommended Operating Conditions (1) (2) MIN NOM MAX UNIT VCC, Supply voltage 3.15 3.3 3.45 V BIAS VCC Control inputs or A port VCC 5.5 VI Input voltage V B port VCC 5.5 Control inputs or A port 2 VIH High-level input voltage V B port 0.5 VCC + 50 mV Control inputs or A port 0.8 VIL Low-level input voltage V B port 0.5 VCC – 50 mV IIK Input clamp current –18 mA 3A port and Y output –12 IOH High-level output current mA B port –48 3A port and Y output 12 IOL Low-level output current mA B port 64 Δt/Δv Input transition rise or fall rate Outputs enabled 10 ns/V Δt/ΔVCC Power-up ramp rate 20 ms/V TA Operating free-air temperature 0 85 °C (1) 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. (2) 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 at any time, 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.
