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.
