[1] H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state.
[2] The nAn, nDIR and nOE input circuit is referenced to VCC(A); The nBn input circuit is referenced to VCC(B).
[3] If at least one of VCC(A) or VCC(B) is at GND level, the device goes into suspend mode.
