74ls373
hai
I am using 74LS373 chip to latch the PORTD output of PIC to illuminate some LEDS. I have no previous experience with this Latch.
As there is no need to enable or disable the output of this latch I have tied the Output Enable pin of this chip to ground so that the output is always latched.
So in software I put the required data into the concerned port and toggle the Latch enable pin of this 74LS373 and the output gets latched into this chip.
So far it is ok.
but after some time the output of the latch turns off or change data. I chechked the software and this change is not happening at any particular portion of code or in a prefixed time.
Is there any experience or suggession you can share?
