Logic, as defined by Webster\'s New World Dictionary, is "the discipline of correct thinking based on reasoning; the science of the human mind." This concept lies at the heart of Buffers, Drivers, Receivers, and Transceivers. A single device may share these logic functions, and the SN74LVC16244AZQLR, an integrated circuit solution, is designed to satisfy these varied applications.

Application Fields

The SN74LVC16244AZQLR, a registered buffer device from Texas Instruments, is a buffer or line driver that is utilized for a variety of applications. It can be used for general purpose, low level, and high speed logic applications, specifically for implementing high performance data transmission structures along with buffering and logic translation. This device can be utilized in Ethernet and high speed logic systems, as well as voice and data communication systems. The device is bidirectional and channel configuration options include 1-bit, 4-bit, and 8-bit, where the channel enables allow separate control of each line.

Architecture

The SN74LVC16244AZQLR is composed of two segmented logic blocks, including 16 non-inverting and 16 inverting line drivers. Each logic block offers individual control of the data being sent and received. In addition, the device includes independent supply line for transmitter and receiver, as well as separate logic ground line for each block. This helps to improve electrical noise immunity.

Power Specifications

The SN74LVC16244AZQLR operates using two power supplies (VccA for transmitter and VccB for receiver). Each power supply needs to be able to provide up to 5.5V max. The ground supply line (GND) supplies electrical common reference voltage for each power line. When powered up, the device achieves a steady state power consumption of under 30mW.

Operation

The SN74LVC16244AZQLR is used to translate standard logic signals including LVCMOS, LVTTL and SSTL signals. The device is capable of providing output data in 3-state logic with levels that range from 0.8V to 2.6V (when powered by the minimum voltage requirement). Four channel enable inputs are available to select one channel at a time.

Output Structure

The SN74LVC16244AZQLR features six active output states: High (1), Low (0), Tri-state/High Impedance (Z), Tri-state/High Impedance (Z), Transition-active (T), and Transition-inactive (T_). The outputs can also be used in bus configurations, and the interface voltage can be set as low as 0.8V or high as 5.5V.

Conclusion

The SN74LVC16244AZQLR buffer is an ideal solution for a variety of logic applications and data transmission structures, such as high-speed logic systems and voice/data communications. It is a versatile device, with independent supply lines, six different output states and four channel enables. The device is also designed to improve electrical noise immunity, while consuming less power than other competing solutions. Thanks to these features, the SN74LVC16244AZQLR makes a perfect choice for implementing low-level and high-speed logic.
