*) Type means: A = 100% tested, B = 100% correlation tested, C = Characterized on samples, D = Design parameter
Notes: 1. Delay time between rising edge of input signal at pin CS after data transmission and switch on/off output stages to 90% of
final level. Device not in standby for t > 1 ms.
2. Delay time between rising/falling edge of input signal at pin PWM and switch on/off output stages to 90% of final level.
3. Difference between switch-on and switch-off delay time of input signal at pin PWM to output stages in PWM mode.
