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.
This SN74LVC244APWRG3 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 an operating temperature range of -40 °C to 125 °C. Tape and reel packaging will encase this product during shipment, in order to ensure safe delivery and enable quick mounting of components. It has 8 channels per chip. 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.
The 74LCX244WM is a low voltage non-inverting Buffer/Line Driver with 3-state outputs. The device may be employed as a memory address driver, clock driver and bus-oriented transmitter/receiver. The LCX244 is designed for low voltage (2.5 or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The LCX244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
