74HC2G14; 74HCT2G14
Dual inverting Schmitt trigger
Rev. 2 — 14 March 2014
Product data sheet
1. General description
The 74HC2G14; 74HCT2G14 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 V
CC
. Schmitt trigger inputs transform slowly changing input signals
into sharply defined jitter-free output signals.
2. Features and benefits
Wide supply voltage range from 2.0 V to 6.0 V
Complies with JEDEC standard no. 7A
Input levels:
For 74HC2G14: CMOS level
For 74HCT2G14: TTL level
High noise immunity
Low power dissipation
Balanced propagation delays
Unlimited input rise and fall times
Multiple package options
ESD protection:
HBM JESD22-A114E exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Specified from
40 C
to +85
C
and
40 C
to +125
C
3. Applications
Wave and pulse shaper for highly noisy environments
Astable multivibrators
Monostable multivibrators
