IBHL should be measured after lowering VIN to GND and 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 and 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. || Current into an output in the high state when VO > VCC k High-impedance state during power up or power down h This is the increase in supply current for each input that is at the specified TTL voltage level rather than V CC or GND.
