The best way to check for diodes is look at the absolute max spec Iik and Iok. If current limits a (+/-) then there is a diode to Vcc and Gnd. If there is only a (–) current then there is only a diode to Vcc. If there is no diode to Vcc on the input then it will usually mean that it is over voltage tolerant. If there is no diode on the output it does not usually mean it is over voltage tolerant. There is usually a parasitic diode on the output that will not allow voltages more than .5V over Vcc, but you can go above Vcc if it is in tri-state On most of out little logic parts there will be a Vi and Vo spec. This is the spec the customer should go by. It will tell the customer what is allowed. Most of our devices will not let you pull the output above VCC. There are only a few that will. Some switches and open drain parts. No clamp to VCC on input or output In absolute max spec In absolute max spec In recommended spec Or No clamp to Vcc on input output there is a Vcc clamp on In absolute max spec In recommended spec Clamp to Vcc on both input and output In absolute max spec In recommended spec If there is no diode to Vcc on the input then it will usually mean that it is over voltage tolerant. If there is no diode on the output it does not usually mean it is over voltage tolerant. There is usually a parasitic diode on the output that will not allow voltages more than .5V over Vcc.
