T-Type flip flop from NAND gates

T-Type flip flop from NAND gates

T-Type flip flop from NAND gates

(OP)
Is it possible to construct a T-Type flip flop just from NAND gates?

TIA

RE: T-Type flip flop from NAND gates

It certainly is possible but should only be done as a student exercise.  Old TI data books have schematics of old level sensitive master slave FFs.  These are easilly changed to T type.

Integrated FFs have internal analog design parameters that guarante FF operation.  FFs built from nand gates may not always work depending on differential speed of the gates.

RE: T-Type flip flop from NAND gates

Hi, the theory is that any logic function can be built using 2 input nand gates. Early asics used to be known as "sea of gates".

RE: T-Type flip flop from NAND gates

I heard about some students who were given the task:
Construct a (quite slow I guess) D-FF by using relays.

As I understand, it was not that easy

RE: T-Type flip flop from NAND gates

To be more precisely, the base is a master-slave FF. This is accomplished from two S-R FFs (two NANDs) and associated logic. Then, connect Q output to K (inverting) input and /Q (inverted output) to J (non-inverting input). A T type FF is also a one stage divide-by-2 register.
