Description
Serial Clock Input. Data is clocked into the input shift register on the falling edge of the serial
clock input. Data can be transferred at rates of up to 50 MHz.
Most Positive Power Supply Potential.
Serial Data Input. This device has an 8-bit shift register. Data is clocked into the register on the
falling edge of the serial clock input.
Ground (0 V) Reference.
Source Terminal 1. This pin can be an input or an output.
Drain Terminal 1. This pin can be an input or an output.
Source Terminal 2. This pin can be an input or an output.
Drain Terminal 2. This pin can be an input or an output.
Source Terminal 3. This pin can be an input or an output.
Drain Terminal 3. This pin can be an input or an output.
Source Terminal 4. This pin can be an input or an output.
Drain Terminal 4. This pin can be an input or an output.
Drain Terminal 5. This pin can be an input or an output.
Source Terminal 5. This pin can be an input or an output.
Drain Terminal 6. This pin can be an input or an output.
Source Terminal 6. This pin can be an input or an output.
Drain Terminal 7. This pin can be an input or an output.
Source Terminal 7. This pin can be an input or an output.
Drain Terminal 8. This pin can be an input or an output.
Source Terminal 8. This pin can be an input or an output.
Most Negative Power Supply Potential. In single-supply applications, it can be connected to
ground.
Serial Data Output. This pin can be used for daisy-chaining a number of these devices together or
for reading back the data in the shift register for diagnostic purposes. The serial data is transferred
on the rising edge of SCLK and is valid on the falling edge of the clock. Pull this open-drain output
to the supply with an external resistor.
RESET /Logic Power Supply Input (V
switches are open, and appropriate registers are cleared to 0. Otherwise, it is the logic power
supply input that operates from 2.7 V to 5.5 V.
