NTB0101A
Auto direction sensing dual supply
6.2 Pin description
7. Functional description
[1] H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state.
[2] When either V
CC(A)
or V
CC(B)
is at GND level, the device goes into power-down mode.
8. Limiting values
[1] If the input and output current ratings are observed, the minimum input and minimum output voltage ratings may be exceeded.
[2] V
CCO
is the supply voltage associated with the output.
[3] V
CCO
+ 0.5 V should not exceed 6.5 V.
[4] Above 87.5 C, the value of P
tot
derates linearly with 4.0 mW/K.
