NOTES:
1. Typical values are at V

A
= 25°C.
2. Trip current definition (see Functional Block Diagram):
An external driver must source at least I
TL
to switch the node fromLOW to HIGH.
An external driver must sink at least I
TH
to switch the node fromHIGH to LOW.
3. Hold current definition (see Functional Block Diagram):
I

IL
max.
I
HL
is the MaximumCurent the QS3389 can source without lowering the node below V
IH
mn.
4. An external driver must provide at least I
BH
during transition to guarantee that the Bus-Hold input will change states.
5. I
BH
is the magnitude of the input current specified under two conditions:
a) Input voltage at GND or Vcc. This indicates the input current under steady-state condition.
b) Input voltage between 0.8V and 2V (TTL input threshold range). This indicates the maximuminput current during transient condition. The driver connected to the
input must overcome this current requirement in order to switch the logic state of the bus-hold circuit.
6. I
BHL
is the mnimumsustaining “sink” current at the input for V
IN
= 0.8V. This parameter signifies the latching capability of the bus-hold circuit in logic LOW state.
7. I
BHH
is the mnimumsustaining “source” current at the input for V
IN
= 2V. This parameter signifies the latching capability of the bus-hold circuit in logic HIGH state.
