description
The SN54LVC14A hex Schmitt-trigger inverter is
designed for 2.7-V to 3.6-V VCC operation and the
SN74LVC14A hex Schmitt-trigger inverter is
designed for 1.65-V to 3.6-V VCC operation.
The devices contain six independent inverters,
and perform the Boolean function Y = A.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators
in a mixed 3.3-V/5-V system environment.
The SN54LVC14A is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74LVC14A is characterized for operation from –40°C to 85°C.
