Philips Semiconductors
Hex non-inverting precision Schmitt-trigger
Product specification
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 × V_CC. 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.

Notes to the quick reference data
1. C_PD is used to determine the dynamic power dissipation (P_D in µW):
P_D = C_PD × V_CC2 × f_i + ∑ (C_L × V_CC2 × f_o) where:
f_i = input frequency in MHz.
f_o = output frequency in MHz.
C_L = output load capacitance in pF.
V_CC = supply voltage in V.
∑ (C_L × V_CC2 × f_o) = sum of outputs.
2. For HC the condition is V_I = GND to V_CC.
