I thin you can follow following steps to
construct a T FLIPFLOP by using Mux:
1) use Mux to construct two latch
2) use these two latch to
construct a edge triggered DFF.
3) use this DFF and Mux to construct a TFF.

tl494 schematic circuit
I've found some topics on TL494,
you can download them, I think
they are useful.

eprom state machine
PROM can only generate next logic and output logic for a state machine,
PROM's address is current state input and other input,
PROM's data is next logic and outputs.
you can read PROM's content and convert them into truth table,
perhaps use some logic reduction...
I think value 1 input will consume less power,
because DFF's internal logic needn't
change, but for input 0, the dff's internal
logic will change, and internal node
will be charged or discharged, consume
greater power consumption.
cmos power consumption formula: P = C*V*V*f
(C...
I design digital system with DFFs, not use latch,
In dff design, if a function is implemented by
a pipelined structure, we can move some combinational
logic between adjacent DFFs to balance timing and
get higher operating frequency, this called timing
borrowing. moving...
Re: buffers
buffer has two functions:
1) for fixing hold time, we add buffer before a dff's inputs to increase
data delay.
2) for fixing transition time violation, we add buffers to
increase drive ability. but in these case, buffer also
increase delay by itself, but...
