概述

Description

SN74LVTH162244DLR is a 16‑bit buffer/driver with tri‑state outputs from TI’s LVTH family. It provides two independent 8‑bit buffers (two enable pins) for buffering a 16‑bit data bus and can place its outputs in high-impedance when not driving the bus.
Key features:
- 16‑bit, noninverting buffer/driver; two 8‑bit sections
- Two output‑enable inputs to tri‑state the corresponding outputs
- Low-voltage CMOS operation: typically 1.65 V to 3.6 V; TTL/CMOS input thresholds
- Fast CMOS performance suitable for bus buffering and interfacing
- Lead-free, RoHS-compliant package (DLR suffix denotes packaging/reel options)
Typical uses:
- Buffering a 16‑bit data bus between a microcontroller/FPGA and memory or peripherals
- Interfacing devices across different voltage domains
- Isolating bus lines to prevent contention on shared buses
Note: DLR indicates packaging options for RoHS/compliant, reel/tape packaging.

Features

Here are the key features of SN74LVTH162244DLR (TI):
- 16-bit buffer/driver with 3-state outputs
- Two 8-bit buffers in one package, each with its own active-low output enable (OE1 and OE2)
- Bus-hold on all data inputs (no external pull-ups/pull-downs required)
- Low-voltage operation: VCC = 1.65 V to 3.6 V (LVTH family)
- High-speed CMOS performance
- TTL/CMOS-compatible input thresholds
- Very low static power consumption
- ESD protection and robust operation for standard digital buses
- Pb-free (DLP/DLR package variant) and suitable for surface-mount applications
Note: Always check the latest datasheet for exact electrical characteristics and recommended operating conditions.

Package

20-pin Small Outline Integrated Circuit (SOIC) package (D package), lead-free, Tape & Reel.

Pinout

- Pin count: 20 pins (SOIC-20/TSSOP-20).
- Function: SN74LVTH162244DLR is a 16-bit buffer/driver with tri-state outputs (two 8-bit sections). It buffers data from A0–A15 to Y0–Y15 with independent output-enable controls (OE1, OE2) for each 8-bit group.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational technology company that designs and manufactures semiconductors and electronic ICs (analog, digital, and embedded processing), and is one of the world's largest semiconductor makers.

Application

- 16-bit data and address bus buffering/expansion for microprocessors/microcontrollers
- Bus interfacing with tri-state outputs for memory and I/O devices
- Demultiplexing and level shifting between voltage domains (e.g., 3.3V to 5V)
- Backplane/front-end system buses in embedded, telecom, and consumer equipment
- High-speed data routing and I/O expansion for FPGAs/ASICs
