NOTE: Electrical parameters are guaranteed over the specifi ed ambient operating temperature range, which is established
when the device is mounted in a test socket with maintained transverse airfl ow greater than 500 lfpm. The device will meet
specifi cations after thermal equilibrium has been reached under these conditions.
NOTE: All parameters measured at 166MHz unless noted otherwise.
