The 74ALVCH32374BF is a 3-state non-inverting octal bus transceiver and register designed for high speed and low power. Complementing the 74LVC32x family of logic, the 74ALVCH32374BF is a logic device pinning for dual asynchronous outputs. It converts 3-state logic levels to other logic families, allowing for more flexibility in device design when interfacing with logic families. The device is also suitable for extending 3-state logic beyond the scope of other logic families, greatly increasing the capabilities of the overall system design.

The 74ALVCH32374BF is ideal for many applications where high speed and low power are required. It is typically used where data buffering or data flow control is necessary. Typical applications include bus buffering, bus extension and transmission, register-to-register hopping, systems clocks synchronization, and the like. It can also be used to connect async TTL logic to various logic families, and can buffer and convert TTL buffers to higher speed logging standards, such as LVTTL, LVCMOS, PCIe, etc.

The 74ALVCH32374BF’s working principle is quite simple. It is comprised of two, three-state registers. Each register has an input and output port. The two registers are clocked by two independent clocks, allowing for asynchronous data transfer between two independent outputs. Data can be sent from the input port to the output port, and vice versa. By controlling the input and output ports, a data flip-flop along with a set-reset latch, is created. The two clocks allow for data to flow from one port to the other, synchronously and/or asynchronously.

The 74ALVCH32374BF also has two levels of “limiting” voltage settings. These settings adjust the output level of the circuit, limiting the logic levels of the output signals to match the logic level of the output to input voltage levels. This allows for a more efficient and consistent data transfer. In addition, the device also features a low-range-clock input, low-range-clock output, and direct clock input lines.

In conclusion, the 74ALVCH32374BF is an ideal 3-state octal transceiver and register, suitable for many applications where high speed and low power consumption are necessary. The device features two independent clocks, allowing for asynchronous data transfer between two independent outputs, and two levels of “limiting” voltage settings, specifically designed to adjust the output level. With its simple but effective design, it is a very reliable and versatile flip-flop ideal for any application.
