IBHL should be measured after lowering VIN to GND, then raising it to VIL max. ¶ The bus-hold circuit can source at least the minimum high sustaining current at VIH min. IBHH should be measured after raising VIN to VCC, then lowering it to VIH min. # An external driver must source at least IBHLO to switch this node from low to high. || An external driver must sink at least IBHHO to switch this node from high to low. k High-impedance state during power up or power down |
