ON Semiconductor 74LCX16374MEA Low Voltage 16-Bit D-Type Flip-Flop

The 74LCX16374MEA from ON Semiconductor is a high-performance, low-voltage 16-bit D-type flip-flop with a bus interface designed for use in systems that require low power consumption and high data bandwidth. This device is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. With its robust design, it can operate at a voltage range of 2.3V to 3.6V, making it incredibly versatile for modern low-voltage applications.

The 74LCX16374MEA features multiple functionalities that make it an excellent choice for system designers. It has an edge-triggered D-type input which ensures that data is synchronized with the clock input to avoid timing issues. The device also comes with a 5V tolerant I/O, allowing it to interface with 5V systems, thereby providing a bridge between different voltage domains.

One of the key attributes of this flip-flop is its power-down high impedance inputs and outputs, which significantly reduce power consumption when the device is not in active use. This is particularly beneficial for battery-operated devices where energy efficiency is critical. Additionally, the 74LCX16374MEA supports live insertion and withdrawal (hot swapping), which is essential for systems that require maintenance or upgrades without power shutdown.

The device is also equipped with an output enable (OE) and a clear (CLR) input, which provide additional control over the output states. The OE input allows the user to place the outputs in either a high-impedance state or active state, while the CLR input can be used to reset the flip-flop outputs to a predetermined value, ensuring a predictable start-up state.

ON Semiconductor's 74LCX16374MEA is packaged in a 48-lead SSOP (Shrink Small Outline Package), offering a compact footprint for space-constrained applications. This product is characterized for operation from -40°C to +85°C, ensuring reliable performance across a wide range of operating conditions. With its combination of low-voltage operation, high-speed interface, and power-saving features, the 74LCX16374MEA is an ideal solution for a variety of digital logic applications.
