Other Parts Discussed in Thread: SN74AUP1T34
Hello
I would like to use the output of one LSF0102 as the Vref/Enable of four other LSF0102 devices. The device driving the initial input (CONF_EN_1V8) is an Intel MAXII CPLD with up to 2mA drive capability at 1.8V. Given that the LSF0102 should only be sinking 17uA (through a 200kOhm resistor), this should be enough to drive the Vref and Enable pins of four other LS0102 devices? Is my thinking correct or is there something that I am overlooking with regard to the switching transistor in the LSF0102. Any help would be appreciated. Thanks in advance.
I have placed (an untidy, my apologies) diagram below for reference. The highlights show the intended application.
