DESCRIPTION/ORDERING INFORMATION
This octal buffer/driver is designed for 2.7-V to 3.6-V V_CC operation.
The SN74LVCZ240A is designed specifically to improve the performance and density of 3-state memory address
drivers, clock drivers, and bus-oriented receivers and transmitters.
This device is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low,
the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the
high-impedance state.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in
a mixed 3.3-V/5-V system environment.
