Hello everyone, I'm using a load of cascaded 74HC595s to drive a few bargraph LEDs, however instead of using a microcontroller to use them, i'm using pure logic.
I have the data inputs tied high so a continuous stream of logic high is fed in, shift register clock, MR and /OE are used as usual.
I'm not quite sure what to do with strobe and latch clock though. Going by datasheets it looks like the latch clock is simply the shift register clock inverted, so that shouldn't be a problem (I hope?). The main problem is strobe, the datasheet shows either high or doesn't matter for all functions, so if this is held high will it prevent the shift register functioning?
Any help would be greatly appreciated, almost all the resources I've found online just mention the datasheet and are almost entirely geared towards Arduino use. Thanks everyone
