NXP 74ALVCH16543DGGS - 16-Bit Registered Transceiver with Dual Voltage Interface

The NXP 74ALVCH16543DGGS is a high-performance, 16-bit registered transceiver that is designed to address the needs of high-speed bidirectional communication between data buses. It is part of NXP's advanced high-speed CMOS family, featuring a dual voltage interface and a bus hold feature that eliminates the need for external pull-up or pull-down resistors.

This integrated circuit offers a wide voltage range of operation, from 1.65V to 3.6V, making it suitable for interfacing with both 3.3V and 2.5V logic levels. This flexibility ensures that the 74ALVCH16543DGGS can be used in a variety of systems that require level translation or direct interfacing with different logic levels.

The device features 16-bit bus transceiver registers with 3-state outputs, which are capable of driving heavily loaded buses with up to 24 mA of current. The 3-state outputs allow for connection to a bus without affecting the bus when the output is disabled. The 74ALVCH16543DGGS also boasts low on-state resistance, which reduces power consumption and improves signal integrity.

The registers are edge-triggered D-type flip-flops that feature individual data inputs (Dn) and outputs (Qn), as well as a direct output enable (OE) control. This enables the user to control the flow of data from input to output. The device also supports live insertion and extraction, minimizing the potential for glitches on the data bus during hot swapping operations.

The NXP 74ALVCH16543DGGS comes in a TSSOP56 (Thin Shrink Small Outline Package) form factor, which is ideal for space-constrained applications. It is characterized for operation from -40°C to +85°C, ensuring reliable performance across a broad range of industrial temperatures.

With its robust feature set, the NXP 74ALVCH16543DGGS is an excellent choice for applications requiring high-speed data transfer, level translation, or bus interface operations in computing, networking, and telecommunications equipment.
