NXP 74LVC16374ADGG: A 16-Bit Edge-Triggered D-Type Flip-Flop with 3V Operation and 5V Tolerant Inputs/Outputs

In the realm of digital logic design, efficiently managing data flow across multiple bits while interfacing between different voltage domains is a common and critical challenge. The NXP 74LVC16374ADGG addresses this need directly, offering a high-performance, 16-bit solution that excels in mixed-voltage environments. This integrated circuit is a 16-bit edge-triggered D-type flip-flop featuring separate data (D), clock (CP), and output enable (OE) inputs for each byte, providing designers with flexible control.

A defining characteristic of this device is its 3V operation, with a recommended supply voltage range of 1.65V to 3.6V. This makes it ideally suited for modern low-power, battery-operated devices and core logic within 3.3V and 2.5V systems. Despite its low-voltage core, a key feature is its 5V tolerant inputs and outputs. This capability allows the flip-flop to safely accept input signals from legacy 5V logic devices without the need for an external level-shifter, simplifying board design and reducing component count. The outputs can also drive 5V inputs, making it a perfect bidirectional translator in mixed-voltage systems.

The 74LVC16374ADGG utilizes positive-edge triggering. On each low-to-high transition of the clock signal, the data present at the D-inputs is transferred to the Q outputs. The outputs are placed in a high-impedance state when the output enable (OE) is set high, facilitating easy connection to a bus-oriented system without causing contention. Housed in a TSSOP-48 package, it offers a compact footprint for high-density PCB designs.

Furthermore, the IC incorporates robust ESD protection, exceeding 2kV, which enhances the reliability of the end product. Its ability to support live insertion and removal adds to its versatility in advanced applications.

ICGOOODFIND: The NXP 74LVC16374ADGG is an exceptional choice for designers needing a high-density, 16-bit register for data storage, buffering, or synchronization. Its 5V tolerance eliminates the need for external voltage translation components, making it a cost-effective and space-efficient solution for bridging voltage gaps in complex digital systems.
