Pin Configurations(1,2)
NOTES:
1. All VCC pins must be connected to the power supply.
2. All GND pins must be connected to the ground supply
Absolute Maximum Ratings(1)
NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above those
indicated in the operational sections of this specification is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect
reliability.
2. VTERM must not exceed Vcc + 10% for more than 25% of the cycle time or 10ns
maximum, and is limited to < 20mA for the period of VTERM > VCC + 10%.
Capacitance(1)
(TA = +25°C, f = 1.0MHz) TQFP only
NOTES:
1. This parameter is determined by device characterization but is not
production tested.
2. 3dV references the interpolated capacitance when the input and
the output signals switch from 0V to 3V or from 3V to 0V.
Maximum Operating
Temperature and Supply Voltage(1)
Recommended DC Operating
Conditions
NOTES:
1. VIL
> -1.5V for pulse width less than 10ns.
2. VTERM must not exceed Vcc + 10%.
NOTES:
1. This is the parameter TA. This is the "instant on" case temperature.
