General Description
The ’AC/’ACT258 is a quad 2-input multiplexer with
TRI-STATE outputs. Four bits of data from two sources can
be selected using a common data select input. The four out-
puts present the selected data in the complement (inverted)
form. The outputs may be switched to a high impedance
state with a HIGH on the common Output Enable (OE) input,
allowing the outputs to interface directly with bus-oriented
systems.

Has anyone used the PSMC function of PIC16F1783? How to understand the burst mode?
I recently used the PSMC function of PIC16F1783 to adjust the BOOST circuit, but the problem is that the frequency I use now is 500K, single-phase PWM mode, and the resolution of the dot-to-space rati...
