Notes:
*3 The VCC supply must be bypassed by a 0.1µF capacitor or larger. This can be either a ceramic or solid
tantalum capacitor with good high frequency characteristic and should be connected as close as possible to
the package VCC and GND pins
*4. Enable Input – No pull up resistor required as the device has an internal pull up resistor.
*5. tPLH
–
Propagation delay is measured from the 3.75mA level on the HIGH to LOW transition of the input
current pulse to the 1.5 V level on the LOW to HIGH transition of the output voltage pulse.
*6. tPHL
–
Propagation delay is measured from the 3.75mA level on the LOW to HIGH transition of the input
current pulse to the 1.5 V level on the HIGH to LOW transition of the output voltage pulse.
*7. tr
–
Rise time is measured from the 90% to the 10% levels on the LOW to HIGH transition of the output
pulse.
*8. tf
–
Fall time is measured from the 10% to the 90% levels on the HIGH to LOW transition of the output
pulse.
*9. tELH
–
Enable input propagation delay is measured from the 1.5V level on the HIGH to LOW transition of
the input voltage pulse to the 1.5V level on the LOW to HIGH transition of the output voltage pulse.
*10. tEHL
–
Enable input propagation delay is measured from the 1.5V level on the LOW to HIGH transition of
the input voltage pulse to the 1.5V level on the HIGH to LOW transition of the output voltage pulse.
*11 CMH– The maximum tolerable rate of rise of the common mode voltage to ensure the output will remain in
the HIGH state (i.e., VOUT > 2.0V).
*12 CML– The maximum tolerable rate of rise of the common mode voltage to ensure the output will remain in
the LOW output state (i.e., VOUT < 0.8V).
