AC Characteristics

1. INPUT SETUP AND HOLD TIME :

KEY Trigger Mode : S1 to S8 hold time, th (min.) = 22ms @ 6K Hz sampling

CPU Trigger Mode : SBT setup time ts (min.) = 1us, and

S1 to S5 hold time th (min.) = 22ms @ 6K Hz sampling

Note: Input hold time th is inverse proportional to the sampling frequency.

2. OUTPUTS DELAY TIME :

STOP : Delay time td (max.) = 1us, plus width tw (min.) = 64ms @ 6K Hz sampling

Note: The pulse width tw is inverse proportional to the sampling frequency.

BUSY : Delay time td (max.) = 1us, hold time th (max.) = 1us @ 6K Hz sampling

Note: The BUSY delay time td and hold time th is fixed and

independent of sampling frequency.
