MC74LCX14
Low Voltage CMOS
Hex Schmitt Inverter With
5 V-Tolerant Inputs
The MC74LCX14 is a high performance hex inverter with
Schmitt−Trigger inputs operating from a 2.3 to 3.6 V supply. High
impedance TTL compatible inputs significantly reduce current
loading to input drivers, while TTL compatible outputs offer improved
switching noise performance. A V
I
specification of 5.5 V allows
MC74LCX14 inputs to be safely driven from 5.0 V devices.
Pin configuration and function are the same as the MC74LCX04,
but the inputs have hysteresis and, with its Schmitt trigger function,
the LCX14 can be used as a line receiver which will receive slow input
signals.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
