74HC2G14; 74HCT2G14
Dual inverting Schmitt trigger
Rev. 01 -- 11 October 2006 Product data sheet
1. General description
The 74HC2G14; 74HCT2G14 is a high-speed Si-gate CMOS device. The 74HC2G14; 74HCT2G14 provides two inverting buffers with Schmitt trigger action which accept standard input signals. They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. The inputs switch at different points for positive and negative-going signals. The difference between the positive voltage VT+ and the negative voltage VT- is defined as the input hysteresis voltage VH.

16. Application information
The slow input rise and fall times cause additional power dissipation, this can be calculated using the following formula: Padd = fi x (tr x ICC(AV) + tf x ICC(AV)) x VCC where: Padd = additional power dissipation (W); fi = input frequency (MHz); tr = input rise time (ns); 10 % to 90 %; tf = 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 74HC2G14/74HCT2G14 is shown in Figure 13.
