U U U PIN FUNCTIONS S0, S1, S2, S3, S4, S5, S6, S7 (Pins 1, 2, 3, 4, 5, 6, 7, DIN (Pin 12):
Digital Input (TTL/CMOS Compatible). Input
8):
Analog Multiplexer Inputs. for the channel selection bits.
GND (Pin 9):
Digital Ground. Connect to system ground.
DOUT (Pin 13):
Digital Output (TTL/CMOS Compatible). Output from the internal shift register.
CLK (Pin 10):
System Clock (TTL/CMOS Compatible). The clock synchronizes the channel selection bits and the
V – (Pin 14):
Negative Supply. For ±5V dual supply appli- serial data transfer from DIN to DOUT. cations, |V– | should not exceed |V+|by more than 20% for proper channel selection.
CS (Pin 11):
Channel Select Input (TTL/CMOS Compat- ible). A logic high on this input enables the LTC1391 to
D (Pin 15):
Analog Multiplexer Output. read in the channel selection bits and allows digital data
V + (Pin 16):
Positive Supply. 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. sn1391 1391fas 5
