[1] Pins are not connected internally, however, pins must be connected to gnd to maintain product family pin for pin compatibility.

[2] this pin is not connected internally, however, this pin must be connected to Vcc to maintain product family pin for pin compatibility.

[3] BiaS ref voltage (pin 20) cannot drive an external load, and must be measured with a 10 gOhm meter such as agilent 34410a; a typical

10 Mohm dVM will read erroneously.
