This SN74LVC244ADW buffer and line driver from Texas Instruments is used to amplify an analog or digital signal by driving the input to the transmission line. With a 3-state output, this is power management at its best. This line driver has a minimum operating temperature of -40 °C and a maximum of 125 °C. This device comes in tube packaging. This non-inverting device has a typical operating supply voltage of 1.8|2.5|3.3 V. Its minimum operating supply voltage of 1.65 V, while its maximum is 3.6 V. It has 8 channels per chip.
The SN74LVC244APWR is an octal Buffer/Driver with 3-state outputs and designed for 1.65 to 3.6V VCC operation. This device is also designed for asynchronous communication between data buses. This device is organized as two 4-bit buffers/line 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. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver.
