Assert this CMOS input pin to the desired voltage for operation. For applications that require the device to only be powered on when the supplies are present, tie the PD pin to the positive supply voltage.
When the PD pin is somewhat below the positive supply pin, slightly more quiescent current is drawn; see Figure 6-56. For the minimum-on power, assert this pin to the positive supply.
The disable operation is referenced from the negative supply; normally, ground. For split-supply operation, with the negative supply below ground, a disable control voltage below ground is required to turn the THS4541 off when the negative supply exceeds –0.7 V.
For single-supply operation, a minimum of 1.7 V greater than the negative supply (ground, in this case) is required to maintain operation. This minimum logic-high level allows for direct operation from 1.8-V supply logic.
