Other Parts Discussed in Thread: SN74ABT125
In of our applications we are using the device SN74ABT125 for HFBR-1414Z LED sink operation.
1) The O/P Pin of the device is connected to the Cathode of HFBR-1414Z to the sink the LED current (60mA). In this scenario the O/P pin of the device SN74ABT125 sees a continuous voltage of 3V when LED is not sinking current( HFBR-1414Z LED Anode voltage- LED Drop).Please suggest if we can use this configuration.
2) Can the O/P pins of the device SN74ABT125 tied together for current sharing during the sink operation.
3)Can Push Pull output pin be pulled high, so that it will see a voltage on its o/p pin.
