SN74AC244PWR devices are logic buffers, drivers, receivers, and transceivers with five inputs and four outputs. The devices are suitable for applications requiring a wide range of voltages at the output and the driver currents required to upgrade data buses. The receiver of the device is two-state and will provide a crisp binary output. SN74AC244PWR is used in various applications such as memory decoding and communications. The device is built with TTL compatible inputs and outputs that can handle a wide supply voltage range from 2V to 6V.

The SN74AC244PWR is an active device, meaning it needs an external power source like Vcc to operate. When the device is powered, the input logic level changes will be sensed. After a logic level change is detected, the appropriate outputs will be driven and the outputs will be in the new state, until the next input level change is detected. When driving data on the bus, the TTL compatibilities field effect transistor (FET) drivers are used. These transistors are designed to guarantee proper bus conditions and are pulled low with a minimum amount of current.

The SN74AC244PWR features four open-drain outputs. The output is driven only when the output enable (OE) input is low. When the OE input is a logic high, the outputs are in a high-impedance state. This allows these outputs to be used in bus applications such as memory mapping and address decoding. The device also contains tri-state inverters with open-drain outputs that allow the user to override the receiver output. The inverters also allow the device to be used as an inexpensive logic inversion function.

The SN74AC244PWR also includes two double-buffered 3-state transceiver circuits, which enable the device to be used in data processing and communications applications. The transceiver uses two buffers that are active in both directions on the bus and will provide faster bus speeds. The receivers are designed to guarantee that all inputs are in the proper logic state when valid transitions occur on the data line. The receivers also provide glitch filters to provide glitch-free data transfers.

The SN74AC244PWR is also designed to reduce power dissipation by only enabling the transistors when valid transitions occur on the bus. This means that the transistors are disabled when the input is at an idle state. The device also provides low standby power and is specifically designed for applications operating on a large bus, such as memory mapping and code executing. The device is also designed for military and industrial applications and is rated for temperatures from -40°C to +125°C.

In summary, the SN74AC244PWR is a logic buffer, driver, receiver and transceiver ideal for applications requiring low standby power, wide voltage operation, and high-speed data transfers. The device is designed with TTL compatible inputs and outputs that can handle a wide supply voltage range from 2V to 6V and has an operating temperature range of -40°C to +125°C. The device also contains four open-drain outputs and two double-buffered 3-state transceiver circuits to provide high-speed data transfers. The device is suitable for a wide range of applications such as memory decoding, communications, and military and industrial applications.
