1–12, 25–40, 1–12, 25–40, Sxx
Source. May be an input or output.
45–48
13, 14
VDD
Power Supply Input. These parts can be operated from a single supply of 1.8 V to 5.5 V
and a dual supply of
±2.5 V.
17
SYNC
Active Low Control Input. This is the frame synchronization signal for the input
data. When
SYNC goes low, it powers on the SCLK and DIN buffers and the input
Shift Register is enabled. An 8-bit counter is also enabled. Data is transferred on the
falling edges of the following clocks. After eight falling clock edges, switch conditions
are automatically updated.
SYNC may be used to frame the signal or just pulled low
for a short period of time to enable the counter and input buffers.
18
DIN
Serial Data Input. Data is clocked into the 8-bit Input Register MSB first on the falling
edge of the serial clock input.
19
SCLK
Serial Clock Input. Data is clocked into the Input Shift Register on the falling edge of
the serial clock input. These devices can accommodate serial input rates of up to 30 MHz.
23
GND
Ground Reference
24
VSS
Most Negative Power Supply in a Dual-Supply Application. In single-supply applications,
connect to GND.
