1. INPUT/OUTPUT LOGIC : HO has positive logic with reference to IN. LO has negative logic with reference to IN.
2. LOGIC DURING UV(VCC, VBS)ERROR
Error Signal
UV error
UV error
(VCC)
(VBS)
HO is locked at “L” level as long as UV error for VBS is
detected.
After VBS exceeds VBSUVRESET level, the lock for HO is
removed following an “L” state of the IN signal, and then HO
responds to the input.
HO outputs “L” level as long as UV error for VCC is detected.
HO responds to IN if VCC exceeds VCCUVRESET level.

LO is locked at “L” level as long as UV error for VCC is
detected.
After VCC exceeds VCCUVRESET level, the lock for LO is
removed following an “H” state of the IN signal, and then LO
responds to the input.
LO is independent of VBS to respond to IN.
