description

This octal buffer/driver is designed for 2.7-V to 3.6-V V

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 these devices as translators

in a mixed 3.3-V/5-V system environment.

When V

is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down.

However, to ensure the high-impedance state above 1.5 V, OE should be tied to V

the minimum value of the resistor is determined by the current-sinking capability of the driver.

through a pullup resistor;

This device is fully specified for hot-insertion applications using I and power-up 3-state. The I circuitry

off

disables the outputs, preventing damaging current backflow through the device when it is powered down. The

power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,

which prevents driver conflict.

The SN74LVCZ240A is characterized for operation from –40°C to 85°C.
