Inverting Schmitt-trigger 74HC1G14; 74HCT1G14
FEATURES
• Wide operating voltage range:
2.0 to 6.0 V
• Symmetrical output impedance
• High noise immunity
• Low power dissipation
• Balanced propagation delays
• Very small 5 pins package
• Applications
– Wave and pulse shapers
– Astable multivibrators
– Monostable multivibrators
• Output capability: standard.
DESCRIPTION
The 74HC1G/HCT1G14 is a
high-speed Si-gate CMOS device.
The 74HC1G/HCT1G14 provides the
inverting buffer function with
Schmitt-trigger action. These devices
are capable of transforming slowly
changing input signals into sharply
defined, jitter-free output signals.
