description

These octal buffers/drivers are designed specifically forlow-voltage (3.3-V) V_CC operation with the capability toprovide a TTL interface to a 5-V system environment.

These devices are organized as two 4-bit line drivers withseparate output-enable ()inputs. When is low, thedevice passes data from the A inputs to the Y outputs. When is high, the outputs are in thehigh-impedance state.

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

The SN74LVTZ244 is available in TI's shrink small-outline package(DB), which provides the same I/O pin count and functionality ofstandard small-outline packages in less than half theprinted-circuit-board area.

The SN54LVTZ244 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. TheSN74LVTZ244 is characterized for operation from -40°C to85°C.
