Temperature range: T
MIN
to T
MAX
: −40°C to +85°C at 50 MHz and 140 MHz, and 0°C to 70°C at 240 MHz.

Timing specifications are measured with input levels of 3.0 V (V
IH
) and 0 V (V
IL
) for both 5 V and 3.3 V supplies.
4
Rise time was measured from the 10% to 90% point of zero to full-scale transition, and fall time from the 90% to 10% point of a full-scale transition.
5
Measured from 50% point of full-scale transition to 2% of final value.
