† _{Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and}
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

1. Tested with outputs disabled (IOUT = 0)
2. RCLK and WCLK switch at 20 MHz and data inputs switch at 10 MHz.
3. Typical ICC1 = 2.04 + 0.88 × fS + 0.02 × CL × fS (in mA). These equations are valid under the following conditions:
VCC = 3.3 V, TA = 25°C, fS = WCLK frequency = RCLK frequency (in MHz, using TTL levels), data switching at fS/2, CL = capacitive
load (in pF).
4. All inputs = (VCC – 0.2 V) or (GND + 0.2 V), except RCLK and WCLK, which switch at 20 MHz.
