Input low state voltage
(D0 ... D7, DIS, CS, WR)
Input high state voltage
(D0 ... D7, DIS, CS, WR)
Input voltage hysteresis
(D0 ... D7, DIS, CS, WR)
Input pull down current
(D0 ... D7, DIS)
Input pull up current
(CS, WR)
Output disable time (transition DIS to logic low)
Normal operation
Turn-off time to 10% V
R
Output disable time (transition DIS to logic low)
Disturbed operation
Turn-off time to 10% V
R
1) The time includes the turn-on/off time of the high-side switch and the transmission time via the coreless transformer.
2) If Pin DIS is set to low the outputs are set to low; after DIS set to high a new write cycle is necessary to set the output again.
3) The parameter is not subject to production test - verified by design/characterization
