Logic Buffers, Drivers, Receivers, Transceivers are integral components of any electrical system and in most cases play an important role in connecting components of the system to each other. In search for such kind of device end users demand reliable products which are not only cost effective but also accommodate for a wide range of applications. On this basis, the SN74ABT2244ADW is an ideal component for the purpose.

The SN74ABT2244ADW is a quad transistor featuring four independent so called 2-Input NAND buffers. This device is uses a standard single power-supply configuration of 3V to 15V range and supports voltage levels of 1.5V to 6V and logic levels up to 7.5V. The device is designed to use a low card and save power by consuming 1mA max average current. Depending on the particular model this device may also have controlled type inputs which can be used in order to minimize noise to the device. Output levels are valid up to VCC + 0.5V.

The SN74ABT2244ADW is a very popular device mainly because of its wide application range. It is traditionally used for memory interfacing, bus buffering and TTL logic port expansion as well as for converting between standard and logic levels. Due to high speed gates this device can be used in high speed applications. Furthermore, the device may be used with analog signals, especially in pulse width modulation control applications where this device offers good noise immunity and superior edge rate control.

The working principle of the SN74ABT2244ADW is quite simple yet genius. The device operates as a pair of two independent NAND buffers. Each NAND buffer consists of two A-B type inputs which are linked to the output by a pair of NAND gate. When both inputs of NAND gate A and B are HIGH, then the output at the collector is LOW. When either input at gate A or gate B is LOW, then the output at the collector would be HIGH. Moreover, the device is provided with a power input as well as an output tied to ground. It is worth noting that the outputs here are also “open collector” meaning that the output can be pulled up to the power input in order to make a valid logic one.

The SN74ABT2244ADW is a device particularly useful for its range of applications, however, other than that there are a few more advantages of the device. Firstly, the device is a low power consuming device and can be operated solely on a single voltage range, which makes the device ideal for low power applications. Secondly, the device is also fault tolerant thanks to a provision of open drain outputs, which can also be referred onto as ‘wire-or’ functionality within the device. This device is also very easy to interface with external logic as it has an open drain input pin allowing logic levels to be connected directly to logic components.

The SN74ABT2244ADW is a device that comes in many variations and meets almost all standard applications requirements. Owing to its power efficiency and logical operation, it is an ideal choice for many systems from audio and visual to consumer electronics. Even with its open drain inputs, the device is capable to deliver sufficient quality for commercial devices and applications.
