Note 11: This is the total quiescent current requirement for the USB-3102 which includes up to 10 mA for the status
LED. This does not include any potential loading of the digital I/O bits, +5V user terminal, ITEST, or the
VOUTx/IOUTx outputs.
Note 12: Output voltage range assumes USB power supply is within specified limits.
Note 13: This refers to the total amount of current that can be sourced from the +5V user terminal (pin 56) for general
use. This specification also includes any additional contribution due to DIO loading.
Note 14: This refers to the total maximum amount of current that can be sourced from the ITEST user terminal (pin 51).
The ITEST terminal pin should only be used for biasing individual IOUTx outputs in order to facilitate
functional testing. A load resistor of 100Ω should be placed in series between the ITEST pin and the IOUTx pin
for proper operation.
