Product Overview: Texas Instruments 74LVTH16374DLR

The Texas Instruments 74LVTH16374DLR is a high-performance, low-voltage 16-bit D-type edge-triggered flip-flop with 3-state outputs. It is part of the LVT (Low Voltage Technology) family, which operates at a nominal voltage of 3.3V. This integrated circuit is designed to have a high drive capability, making it suitable for bus interface or signal buffering applications requiring high speed and low power consumption.

Featuring a 16-bit wide format, the 74LVTH16374DLR is organized as two 8-bit flip-flops with separate output-enable (OE) inputs for each section. This allows for greater flexibility in control and bus management. The device's inputs and outputs are on opposite sides of the package, which facilitates a simpler PCB layout by improving the flow of data through the circuit.

The flip-flops in the 74LVTH16374DLR capture data on the rising edge of the clock (CLK) input. When the output enable (OE) input is low, the device presents the stored data at the outputs in a non-inverted form. Conversely, when OE is high, the outputs are in a high-impedance state, effectively isolating the bus lines.

Key features of the 74LVTH16374DLR include:

• Support for mixed-mode signal operation, with the ability to handle 5V input and output voltages while operating at a 3.3V Vcc, making it compatible with TTL levels.
• High drive capability with 24mA balanced output sink and source capabilities, providing strong signal driving for buses.
• Low power consumption, with a typical ICC of only 0.8µA in standby mode, contributing to energy-efficient designs.
• Bus Hold on data inputs, which eliminates the need for external pull-up or pull-down resistors, saving board space and reducing component count.
• Flow-through architecture that optimizes PCB layout.
• Latch-up performance that exceeds 500mA per JESD 78, Class II, ensuring robust operation in a variety of applications.

The 74LVTH16374DLR is available in a 48-pin SSOP (Shrink Small Outline Package) that is designed for space-saving and reliable surface-mount applications. This product from Texas Instruments is a versatile and reliable choice for designers looking to implement high-speed data storage and transfer in their digital systems.
