Inverting Schmitt-triggers
Preliminary specification
74HC2G14; 74HCT2G14
FEATURES
Wide supply voltage range from 2.0 to 6.0 V
High noise immunity
Low power dissipation
Balanced propagation delays
Unlimited input rise and fall times
Very small 6 pins package.
APPLICATIONS
Wave and pulse shapers for highly noisy environments

DESCRIPTION
The 74HC2G/HCT2G14 is a high-speed Si-gate CMOS
device.
The 74HC2G/HCT2G14 provides two inverting buffers
with Schmitt-trigger action. This device is capable of
transforming slowly changing input signals into sharply
defined, jitter-free output signals.
QUICK REFERENCE DATA
GND = 0 V; Tamb = 25 °C; tr = tf 6.0 ns.

notes 1 and 2
Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + (CL × VCC2 × fo) where:
fi = input frequency in MHz; fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in Volts;
N = total switching outputs;
(CL × VCC2 × fo) = sum of outputs.
2. For HC2G the condition is VI = GND to VCC.
For HCT2G the condition is VI = GND to VCC 1.5 V.
