Function Table Table 1. Supply Configuration table SEL Input VCC VISO Shorted to VISO 5V 5V Shorted to GND2 or floating 5V 3.3V Shorted to GND2 or floating 3.3V 3.3V Note: 1. VCC = 3.3 V, SEL shorted to VISO (VISO = 5 V) is not recommended mode of configuration. 2. The SEL pin has a weak pul down internal y. For VISO = 3.3 V, the SEL pin should be strongly connected to the GND2 pin in noisy system scenarios. Table 2. Operation Mode Table VCC Input Output Operation H H Normal operation mode: PU A channel’s output fol ows the input state L L Open Default Default output fail-safe mode: If a channel’s input is left open, its output goes to the default high level. PD X Undetermined Note: 1. PU = Powered up (VCC ≥ 2.7 V); PD = Powered down (VCC ≤ 2.1 V); X = Irrelevant; H = High level; L = Low level. 2. The outputs are in undetermined state when VCC < 2.1V. 2023.10.26-A/4
