Mix logic familes

Can or can't I mix logic families

First: the properties of the families

Family TTL
Type Conventional
Typical supply voltage 5 V
Input low 0.0V - 0,8V
Input high 2.2V -5V
Output low 0.0V - 0.4V
Output high 2.6V - 5V

 

 

 

 

 

Family TTL
Type L (low power)
Typical supply voltage 5 V
Input low 0.0V - 0,8V
Input high 2.2V -5V
Output low 0.0V - 0.4V
Output high 2.6V - 5V

 

 

 

 

 

Family TTL
Type H (high speed)
Typical supply voltage 5 V
Input low 0.0V - 0,8V
Input high 2.2V -5V
Output low 0.0V - 0.4V
Output high 2.6V - 5V
