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 kHigh-impedance state during power up or power down PRODUCT PREVIEW information concerns products in the formative or design phase of development. Characteristic data and other specifications are design goals. Texas Instruments reserves the right to change or discontinue these products without notice. |
