SN74LVC161284DL Interface - Buffer, Transceiver from Texas Instruments

The SN74LVC161284DL is a high-performance, 19-bit interface buffer and transceiver designed by Texas Instruments to provide a seamless connection between data buses in a system. This device is particularly suitable for driving high-capacitive loads and low-impedance backplanes, thanks to its robust output drivers and bidirectional data flow capability.

Constructed with advanced LVC (Low-Voltage CMOS) technology, the SN74LVC161284DL operates at a voltage range from 2.7V to 3.6V, which allows for low-power consumption while maintaining a high-speed operation. This makes it an optimal choice for interfacing with 3.3V logic levels in mixed 3.3V/5V systems, as it can also tolerate 5V inputs without any risk of damage.

The device features 19-bit bus transceivers with 3-state outputs, which can be independently controlled, thus providing a great deal of flexibility in managing data flow. The SN74LVC161284DL is equipped with control functions such as output-enable (OE) and direction (DIR) inputs, allowing for easy and precise control of the direction of data flow through the device.

For enhanced data integrity, the SN74LVC161284DL incorporates a power-up 3-state feature that keeps the outputs in a high-impedance state until the power supply has stabilized. This minimizes the potential for erroneous outputs or glitching during power-up sequences.

Furthermore, the SN74LVC161284DL is packaged in a slim, space-saving 56-pin SSOP (Shrink Small-Outline Package), which is ideal for compact PCB layouts and high-density applications. The pinout is designed to match the byte-wide configurations commonly used in standard memory and data buses, ensuring easy integration into a variety of design architectures.

With its combination of low-voltage operation, high-speed data handling, and flexible control options, the SN74LVC161284DL from Texas Instruments is a reliable and efficient solution for buffering and transceiving digital signals in a wide range of electronic applications, including computing, networking, and telecommunications equipment.
