74HC2G14GW-Q100

The 74HC2G14-Q100; 74HCT2G14-Q100 is a dual inverter with Schmitt trigger inputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Schmitt trigger inputs transform slowly changing input signals into sharply defined jitter-free output signals.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.

The slow input rise and fall times cause additional power dissipation, this can be calculated using the following formula:

Padd = f i (t r ICC(AV) + t f ICC(AV)) VCC where:

Padd = additional power dissipation ( W);

f i = input frequency (MHz);

t r = input rise time (ns); 10 % to 90 %;

t f = input fall time (ns); 90 % to 10 %;

ICC(AV) = average additional supply current ( A).

ICC(AV) differs with positive or negative input transitions, as shown in Figure 11 and Figure 12.

An example of a relaxation circuit using the 74HC2G14-Q100; 74HCT2G14-Q100 is shown in Figure 13.
