SO-14
The 74VHC14 device is an advanced high-speed
CMOS hex Schmitt inverter manufactured with
sub-micron silicon gate and double-layer metal
wiring C2MOS technology. The internal circuit is
composed of 3 stages including a buffer output,
which provides high noise immunity and stable
output.
Power-down protection is provided on all inputs
and 0 to 7 V can be accepted on inputs
regardless of the supply voltage. This device can
be used to interface from 5 V to 3 V.
Pin configuration and function are the same as
those of the 74VHC04 device but the 74VHC14
device has hysteresis.
This along with its Schmitt trigger function allows
the device to be used on line receivers with slow
rise/fall input signals.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2 kV ESD immunity and transient excess
voltage.

1. CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current
consumption without load. (Refer to Section 5: Test circuit). Average operating current can be obtained by the following
equation. ICC(opr) = CPD x VCC x fIN + ICC/6 (per gate).
