Product speciﬁcation

Hex non-inverting precision Schmitt-trigger

74HC7014

FEATURES

• Operating voltage 3 to 6 V

• Output capability: standard

• category: SSI

APPLICATIONS

• Wave and pulse shapers for highly

noisy environments

DESCRIPTION

The 74HC7014 is a high-speed

Si-gate CMOS device. It is specified

in compliance with JEDEC standard

no. 7A.

The 74HC7014 provides six precision

Schmitt-triggers with non-inverting

buffers. It is capable of transforming

slowly changing input signals into

sharply defined, jitter-free output

signals. The precisely defined trigger

levels are lying in a window between

0.55

× V

CC and 0.65 × VCC. This

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.

QUICK REFERENCE DATA

GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns

Notes to the quick reference data

1. CPD is used to determine the dynamic power dissipation (PD in µW):

PD = CPD × VCC2 × fi + ∑ (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.

∑ (CL × VCC2 × fo) = sum of outputs.

2. For HC the condition is VI = GND to VCC.
