SN74LVTH16652DGGR - Texas Instruments

The SN74LVTH16652DGGR is a high-performance, 16-bit registered transceiver from Texas Instruments, designed to address the needs of high-speed bidirectional communication between data buses. This integrated circuit is part of the LVTH family, which operates on a lower voltage range and provides improved performance and drive capability without sacrificing power consumption efficiency.

Constructed with a BiCMOS technology, it boasts an impressive voltage range of 2.7V to 3.6V, making it suitable for interfacing with 3.3V logic levels while maintaining 5V tolerant inputs. This feature is critical for mixed-voltage systems, ensuring compatibility and ease of use across different logic levels.

The SN74LVTH16652DGGR provides two sets of eight bidirectional data buses and features separate output-enable (OE) and directional (DIR) controls for each set. This allows for greater flexibility and control in data flow, enabling the device to either operate as two independent 8-bit transceivers or one 16-bit transceiver.

One of the key attributes of this device is its support for bus hold on data inputs, which eliminates the need for external pull-up or pull-down resistors. This feature helps to retain the last active data on the bus if no new data is presented, thereby simplifying board design and reducing component count.

The SN74LVTH16652DGGR comes in a 56-pin TSSOP (Thin Shrink Small Outline Package) form factor, designated by the DGGR suffix. This package is optimized for reduced space on PCBs, making it ideal for compact and densely populated designs.

With its robust latch-up performance that exceeds 250 mA per JESD 17, ESD protection exceeding JESD 22, and the ability to operate over the industrial temperature range of -40°C to 85°C, the SN74LVTH16652DGGR is a reliable choice for critical applications in computing, telecommunication, and industrial markets.

In summary, the SN74LVTH16652DGGR from Texas Instruments is a versatile and reliable solution for high-speed, bidirectional data bus communication, combining performance with power efficiency in a compact package.
