SN74ALVCH16374DGGR

SN74ALVCH16374DGGR is a 16-bit register/buffer from TI’s ALVCH family. It contains two 8-bit storage registers that can be loaded in parallel from inputs D0–D15 on a clock edge, and its 16 outputs (Q0–Q15) are tri-state controllable via an Output Enable. This makes it a versatile bus buffer/latch for interconnecting digital blocks, enabling or isolating the data path as needed. The device is designed for low-voltage, high-speed operation (typical supply range ~1.65 V to 3.6 V) with bus-hold on inputs to stabilize signals. It’s suitable for buffering data between microprocessors, memories, DSPs, FPGAs, or peripherals, and for use in portable or mixed-signal systems where multiple devices share a data bus. The DGGR suffix indicates TI’s RoHS-compliant package (a small-outline/TSSOP-style package). In short, it provides a 16-bit, parallel-load register with tri-state outputs for flexible, high-speed bus interfacing in a compact package.

Equivalent devices (same function: 16-bit register with 3-state outputs) from other vendors include:
- Nexperia: 74ALVCH16374
- ON Semiconductor: MC74ALVCH16374
Other vendors may offer the same part number in their ALVCH family under similar voltage/speed grades. Always verify voltage level (e.g., 3.3V/5V), speed grade, and package (DGGR) for exact compatibility.

Here are the key features of the SN74ALVCH16374DGGR:
- 16-bit register with two 8-bit sections (D-type, parallel-load/register capability)
- 3-state outputs controlled by a single output enable (OE) input
- Ioff for partial-power-down support
- Bus-hold on data inputs (reduces floating inputs)
- Low-voltage operation: typically 1.65 V to 3.6 V
- CMOS/TTL-compatible inputs
- High-speed performance within ALVCH family
- Packaging: DGGR (20-pin VSSOP) format
Note: For exact timing, voltages, and pin functions, please refer to the current TI datasheet.

- Pin count: 20 pins (packages like DGGR, a 20-pin small-outline).
- Function: SN74ALVCH16374DGGR is a 16-bit register/bus-driver with tri-state outputs (two 8-bit registers/latches). It latches parallel data on a clock and can place the 16-bit data onto a bus or tri-state it via an output-enable control.

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational technology company that designs and manufactures semiconductors and integrated circuits, specializing in analog and mixed-signal, digital, and embedded processing devices. It is one of the world’s largest semiconductor producers.

SN74ALVCH16374DGGR is a 16-bit clocked register with 3-state outputs. Suitable application areas:
- Buffering/shaping data and address buses between CPU and memory/peripherals.
- Bus isolation and sharing: OE enables/disables the bus for multi-device backplanes.
- Pipelined data paths and timing alignment in high-speed digital systems.
- Interface between fast logic and slower peripherals/memory in embedded designs.
- Multi-clock-domain data-path buffering for microcontrollers, FPGAs, and ASICs.
- Low-voltage operation (1.65–5.5 V) ideal for portable/embedded applications.

The SN74ALVCH16374DGGR is in a 20‑pin TSSOP (RoHS) package.
