1–12, 25–40, 1–12, 25–40, Sxx Source. May be an input or output. 45–48 45–48 13, 14 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 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 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 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 23 GND Ground Reference 24 24 VSS Most Negative Power Supply in a Dual-Supply Application. In single-supply applications, connect to GND. 41, 43 N/A DA, DB Drain. May be an input or output. N/A 43 D Drain.
