VEE2
Controls the output shutdown
function. High voltage when
open; the Q output is fixed to
Low. Low voltage when
connected to VEE; the D input
results in the Q output with ECL
level. TTL level is also available.

VCC2
Switches the identification
maximum voltage amplitude.
High voltage when open; the
identification maximum voltage
amplitude becomes 40mVp-p.
Low voltage when connected
to VEE; the amplitude becomes
20mVp-p.
