Table 8. ADG714 Pin Function Descriptions Pin No. Mnemonic Description
1 SCLK Serial Clock Input. Data is clocked into the input shift register on the falling edge of the serial clock input. These devices accommodate serial input rates of up to 30 MHz. 2 VDD Positive Analog Supply Voltage. 3 DIN Serial Data Input. Data is clocked into the 8-bit input register on the falling edge of the serial clock input. 4 GND Ground Reference. 5, 7, 9, 11, 14, 16, 18, 20 Sx Source. These pins may be an input or an output. 6, 8, 10, 12, 13, 15, 17, 19 Dx Drain. These pins may be an input or an output. 21 VSS Negative Analog Supply Voltage. For single-supply operation, tie this pin to ground. 22 DOUT Serial Data Output. This pin allows a number of devices to be daisy-chained. Data is clocked out of the input shift register on the rising edge of SCLK. DOUT is an open-drain output that is pulled to the supply with an external pull-up resistor. 23 RESET Active Low Control Input. This pin clears the input register and turns all switches to the off condition. 24 SYNC Active Low Control Input. This pin is the frame synchronization signal for the input data. When SYNC goes low, this pin powers on the SCLK and DIN buffers and the input shift register is enabled. Data is transferred on the falling edges of the following clock cycle. Taking SYNC high updates the switches. Rev.
