Description

General part information

SN74LVTZ244 Series

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

These devices are organized as two 4-bit line drivers with separate output-enable () inputs. Whenis low, the device passes data from the A inputs to the Y outputs. Whenis high, the outputs are in the high-impedance state.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
