74HC2G17; 74HCT2G17
Dual non-inverting Schmitt trigger
Rev. 01 — 6 October 2006
Product data sheet
1. General description
The 74HC2G17; 74HCT2G17 is a high-speed Si-gate CMOS device.
The 74HC2G17; 74HCT2G17 provides two non-inverting Schmitt trigger buffers. 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.
2. Features
I Wide supply voltage range from 2.0 V to 6.0 V
I Complies with JEDEC standard no. 7A
I High noise immunity
I ESD protection:
N HBM JESD22-A114-D exceeds 2000 V
N MM JESD22-A115-A exceeds 200 V
I Low power dissipation
I Balanced propagation delays
I Unlimited input rise and fall times
I Multiple package options
I Specified from −40 °C to +85 °C and −40 °C to +125 °C
3. Applications
I Wave and pulse shaper for highly noisy environments
I Astable multivibrators
I Monostable multivibrators

16. Application information
The slow input rise and fall times cause additional power dissipation, this can be
calculated using the following formula:
Padd = fi × (tr × ∆ICC(AV) + tf × ∆ICC(AV)) × VCC where:
Padd = additional power dissipation (µW);
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 (µA).
∆ICC(AV) differs with positive or negative input transitions, as shown in Figure 11 and
Figure 12.
