Description

General part information

SN74LVTH240 Series

These octal buffers and line drivers are designed specifically for low-voltage (3.3-V) VCCoperation, but with the capability to provide a TTL interface to a 5-V system environment.

These devices are organized as two 4-bit buffer/line drivers with separate output-enable (OE)\ inputs. When OE\ is low, the devices pass data from the A inputs to the Y outputs. When OE\ is high, the outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power down, OE\ should be tied to VCCthrough a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
