Question about replacement of LTC1966 to LTC1967

Question

Hi, 
 Regarding the replacement, the Vss pin of the LTC1966 becomes the NC pin of the LTC1967. 
 Since -5V is connected to the Vss pin, simply replacing it will connect -5V to the NC pin. Is this a problem? 
 Regards, 
 Kazu

Hi Kazu: pin 4 on the LTC1967 is not internally connected, so yes you can leave it connected to -5V. Keep in mind that the inputs of the LTC1967 in this condition will only be valid between 0V and Vcc. Don't put a negative voltage on the inputs of LTC1967, like you can with LTC1966 on +/-5V supplies.)
