The q denotes specifications which apply over the full operating
temperature range.
Note 1: Absolute maximum ratings are those beyond which the safety of
the device may be impaired.
Note 2: Guaranteed by design.
Note 3: Leakage current with a single 3V supply is guaranteed by
correlation with the leakage current of the
±5V supply.
Note 4: Timing specifications with a single 3V supply is guaranteed by
correlation with the timing specifications of the
±5V supply.

PIN FUNCTIONS
UU
U
S0 to S7 (Pins 1 to 8): Analog Multiplexer Inputs/Analog
Demultiplexer Outputs.
GND (Pin 9): Digital Ground. Connect to system ground.
CLK (Pin 10): System Clock (TTL/CMOS Compatible). The
clock synchronizes the channel selection bits and the
serial data transfer from Data 1 to Data 2.
