74HC7014
Hex non-inverting precision Schmitt-trigger
Rev. 4 — 26 November 2015
Product data sheet
1. General description
The 74HC7014 is a hex buffer with precision Schmitt-trigger inputs. The precisely defined
trigger levels are lying in a window between 0.55 VCC and 0.65 VCC. It makes the
circuit suitable to operate in a highly noisy environment. Input shorts are allowed to 1.5 V
and +16 V without disturbing other channels. Inputs include clamp diodes that enable the
use of current limiting resistors to interface inputs to voltages in excess of VCC. Schmitt
trigger inputs transform slowly changing input signals into sharply defined jitter-free output
signals.
2. Features and benefits
Operating voltage 3.0 V to 6.0 V
Complies with JEDEC standard no. 7A
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115A exceeds 200 V
Specified from 40 C to +85 C and from 40 C to +125 C
3. Applications
Wave and pulse shapers for highly noisy environments

tt is the same as tTHL and tTLH.
CPD is used to determine the dynamic power dissipation (PD in W).
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 V;
N = number of inputs switching;
(CL VCC2 fo) = sum of outputs.
