概述

Description

SNJ54LVTH162245WD is TI’s automotive-grade, 16-bit bidirectional buffer/driver (two 8-bit transceivers) with tri-state outputs. It provides a single data bus that can transfer in either direction, controlled by a DIR input, and can be tri-stated with an OE (output enable) control.
Key points:
- Two 8-bit transceivers (A and B sides), data moved based on DIR.
- OE enables/disables all outputs (high-Z when inactive).
- Non-latch, high-speed CMOS, LV logic suitable for low-voltage systems.
- Operates from a low-voltage VCC (typical LV range), enabling interfacing between different voltage domains (e.g., 3.3V and 5V).
- SNJ prefix denotes automotive-qualified device; WD suffix specifies packaging/grade variant.
Common uses:
- Bus bridging and data buffering between microcontrollers and peripherals.
- Level shifting and interfacing across voltage domains.
- Memory I/O buffering and general-purpose bidirectional data paths in automotive/industrial electronics.

Features

Concise features of SNJ54LVTH162245WD:
- 16-bit bidirectional bus transceiver (two 8-bit sections)
- Non-inverting data path (A0–A7 to B0–B7 and vice versa)
- DIR input selects direction (A↔B)
- Active-low OE input to tri-state outputs
- 3-state outputs for bus isolation
- Low-voltage CMOS (LV) family, TTL-compatible inputs
- Automotive-grade SNJ variant with extended temperature range
- Pb-free, RoHS-compliant packaging (WD package)
- Suitable for bus interfacing and back‑to‑back data transfers

Package

The SNJ54LVTH162245WD is in a 20‑pin wide SOIC (surface‑mount) package.

Pinout

- Pin count: 28 pins.
- Function: SNJ54LVTH162245WD is a 16‑bit bidirectional bus transceiver (two 8‑bit sections). It has a global direction input (DIR) and separate output-enable controls for each 8‑bit bank (1OE and 2OE). Data can be transferred between the two buses (A to B or B to A) when enabled; outputs are tri-stated when the corresponding OE is inactive.

Manufacturer

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

Application

Applications:
- Bidirectional 16-bit bus transceiver for buffering/expansion between microprocessors, memory and peripherals.
- Level-shifting between voltage domains (e.g., 3.3 V and 5 V) with bus isolation via 3-state outputs.
- Useful in system buses and memory/interfaces (RAM/ROM, PLDs/ASICs) and I/O expansion in instrumentation and communications.
