1. Monitored in sample lots.
2. In the case of the CF5011AL×, oscillator stop function is built-in. When INHN goes LOW, normal output stops. When INHN goes HIGH, normal output
is not resumed until after the oscillator start-up time has elapsed.

FUNCTIONAL DESCRIPTION
Standby Function
Output three-state function (CF5011AL×, CF5011AN×)
When INHN goes LOW, the oscillator output on Q goes high impedance.
Oscillator stop function (CF5011AL×)
When INHN goes LOW, the oscillator stops.
