概要

Description

The SN74LVTH16374DLR is a TI 16‑bit buffer/driver with tri‑state (3‑state) outputs from the LVTH family. It buffers a 16‑bit data bus and can isolate it from other devices by tri-stating its outputs via an output‑enable control, enabling bus sharing without contention.
Key points:
- 16-bit parallel buffer/driver with 3-state outputs
- Low-voltage operation (Vcc ~1.65–3.6 V); LVTTL/CMOS input compatibility
- Output enable control to place outputs in high impedance
- Used to interface microcontrollers/CPUs to memory, peripherals, or buses; ideal for bus isolation and buffering
- Available in TI RoHS-compliant surface-mount packages (DLR suffix)
For exact pinout, drive strength, propagation delay, and electrical characteristics, consult the SN74LVTH16374DLR datasheet.

Features

Here are the key features of SN74LVTH16374DLR (TI):
- 16-bit D-type register with tri-state outputs (two 8-bit sections)
- Edge-triggered, rising-edge clocking
- Active-low output enable (OE) for 3-state bus operation
- Low-voltage operation (LV series): VCC typically 1.65 V to 3.6 V
- CMOS technology: high-speed, low-power operation
- TTL/CMOS compatible input thresholds
- Suitable for buffering/bus interfacing on microprocessor/mmemory buses
- 100% tested for dynamic performance and ESD protection
- Packaging: standard small-outline (DLR) form factor
Notes: For exact pinout, timing specs (tPD, tCLK, setup/hold), and recommended operating conditions, refer to the TI datasheet.

Package

It comes in a 28‑pin RoHS‑compliant small‑outline package (SOP).

Pinout

- Pin count: 20 pins (DLR package, i.e., 20‑pin SOIC).
- Function: 8-bit D-type latch/register with tri-state outputs (bus buffer/driver). It has D[7:0], Q[7:0], a clock input, an output-enable (OE), plus VCC and GND. When OE is active, Q outputs drive the bus; when OE is disabled, outputs are high-impedance.

Manufacturer

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

Application

SN74LVTH16374DLR is a 16-bit, tri‑state buffer/latch device. Common applications:
- Microprocessor/microcontroller bus buffering and demultiplexing (address/data bus)
- Memory and I/O expansion with 3-state bus drivers
- Data buffering and timing alignment between fast CPUs and slower peripherals
- Level-shifting and interfacing between different logic families
- General-purpose buffering/pipelining in embedded/FPGA-ASIC interfaces
Note: suited for high-speed, low-voltage CMOS environments (LVTTL/TTL compatibility).
