PIN FUNCTIONS
S0, S1, S2, S3, S4, S5, S6, S7 (Pins 1, 2, 3, 4, 5, 6, 7,
8): Analog Multiplexer Inputs.
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 DIN to DOUT.
CS (Pin 11): Channel Select Input (TTL/CMOS Compat-
ible). A logic high on this input enables the LTC1391 to
read in the channel selection bits and allows digital data
transfer from DIN to DOUT. A logic low on this input puts
DOUT into three-state and enables the selected channel for
analog signal transmission.
DIN (Pin 12): Digital Input (TTL/CMOS Compatible). Input
for the channel selection bits.
DOUT (Pin 13): Digital Output (TTL/CMOS Compatible).
Output from the internal shift register.
V – (Pin 14): Negative Supply.
D (Pin 15): Analog Multiplexer Output.
V + (Pin 16): Positive Supply.
