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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The value of VCC is provided in the recommended operating conditions table.
