Description
AY2 AY2 Address Line (Input).
STROBE STROBE (Input): enables function selected by address and data. Address must be stable
before STROBE goes low and DATA must be stable on the rising edge of STROBE.
Active Low.
CS Chip Select (Input): this is used to select the device. Active Low.
DATA DATA (Input): a logic high input will turn on the selected switch and a logic low will turn off
the selected switch. Active High.
VSS
X0, X2,
X4, X6
Ground Reference.
X0, X2, X4 and X6 Analog (Inputs/Outputs): these are connected to the X0, X2, X4 and
X6 rows of the switch array.
RESET
Master RESET (Input): this is used to turn off all switches regardless of the condition of
CS. A 100kΩ internal pull-up resistor is also provided. This can be used in conjunction
with a 0.1µF capacitor (connected to the RESET pin) to perform power-on reset of the
device. Active Low.
Y7 - Y0 Y7 - Y0 Analog (Inputs/Outputs): these are connected to the Y0 - Y7 columns of the
switch array.
VDD
X7, X5,
X3, X1
Positive Power Supply.
X7, X5, X3 and X1 Analog (Inputs/Outputs): these are connected to the X7, X5, X3 and
X1 rows of the switch array.
