SN74LVTH16374DLR

SN74LVTH16374DLR is a 16-bit D-type register/buffer with tri-state outputs from TI’s LVTH family. It provides a 16-bit data path that is captured and held under control of a clock and an output-enable (OE) control, allowing the outputs to be bus-sharing when OE is deasserted. The device is designed for low-voltage CMOS operation and fast data buffering in microprocessor or memory interfaces, where you need to latch or buffer data and then drive a bus only when enabled.
Key points:
- 16-bit register with 3-state outputs
- Clock input and output-enable control
- Suitable for data buffering, bus isolation, and address/data interfacing
- Low-voltage CMOS (LV) device with TI’s standard timing characteristics
- Package: DLR suffix indicates RoHS-compliant small-outline (typical 20-pin) package
For exact pinout, electrical specs, timing diagrams, and Vcc range, consult the TI SN74LVTH16374 datasheet.

Here are the key features of SN74LVTH16374DLR:
- 16-bit storage register with 3-state outputs
- Parallel data inputs (D0–D15) and parallel load capability
- Edge-triggered clock input for synchronous operation
- Asynchronous Master Reset (MR) to clear all bits
- Output Enable (OE) to place outputs in high-impedance state
- Very low-voltage operation: 1.65 V to 3.6 V
- CMOS technology: fast, low power
- Suitable for bus interfacing due to tri-state outputs
- Packaging: DLR (low-profile package variant)

- Pin count: 20 pins
- Function: SN74LVTH16374DLR is an octal (8-bit) D-type transparent latch with 3-state outputs. It has eight data inputs (D0–D7), eight outputs (Q0–Q7), a latch-enable input (LE), and an output-enable input (OE). Data is latched when LE is active; outputs can be tri-stated when OE is active.

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational that designs and manufactures semiconductors and integrated circuits (analog, digital, mixed-signal, embedded processing).

SN74LVTH16374DLR is a 16‑bit buffer/driver with 3‑state outputs for bus interfacing. Common applications:
- Buffering 16‑bit data/address buses between microprocessors/PLDs and memory or peripherals
- Shared bus driving with tri‑state enables to prevent contention
- Level shifting/isolation between voltage domains (e.g., 3.3V controller to 5V devices)
- I/O expansion and peripheral interfacing in embedded systems
- High‑speed data paths requiring buffering and impedance matching
- Signal‑integrity improvement on long lines or multi‑load nets
- Glue logic for memory, LCDs, and other controllers in MCU/FPGA design
