概述

Description

SN74ALVCF162835GR is a 20‑bit, non‑inverting buffer/driver with 3‑state outputs. It buffers a 20‑bit data bus (A0–A19) to Q0–Q19 under a single Output Enable (OE); when OE is deasserted, all outputs go tri‑state. It belongs to TI’s ALVC family, offering high speed with a wide supply range (typical 1.65 V to 3.6 V), suitable for buffering and level‑shifting between different voltage domains. Features often include Ioff (partial power‑down) support and low‑power CMOS operation. The “GR” suffix indicates RoHS/compliant, green packaging. Typical uses include data‑bus buffering, inter‑board or inter‑device signaling, and interface buffering in microprocessor or DSP systems. For exact electrical specs (VOH, VOL, VIH/VIL thresholds, input leakage, propagation delay, operating temperature), and available package options, refer to the TI datasheet and product page.

Features

Here are the key features of the SN74ALVCF162835GR (typical from TI datasheet):
- 36-bit buffer/driver with 3-state outputs
- Two 18-bit banks with independent output-enable control
- Advanced low-voltage CMOS (ALVC) technology
- Wide supply range: typically 1.65 V to 3.6 V
- TTL/CMOS input-compatible; suitable for interfacing different logic levels
- 3-state outputs enable bus sharing across devices
- Low power consumption
- ESD protection and robust latch-up immunity
- RoHS-compliant Green packaging (GR)
Note: For exact voltage, timing, and package details, please consult the latest TI datasheet.

Package

It ships in a 20-pin TSSOP (Thin Shrink Small Outline) package. The GR suffix indicates Pb-free, RoHS-compliant (green) packaging.

Pinout

- Pin count: 28 pins (packages like TSSOP/SOIC GR).
- Function: 16-bit bidirectional buffer/driver (bus transceiver) with tri-state outputs. Uses a direction control (DIR) and an output-enable (OE) to buffer a 16-bit data bus and tri-state the outputs as needed.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: American multinational semiconductor company that designs and manufactures analog and digital integrated circuits and related products.

Application

SN74ALVCF162835GR is a 16-bit buffer/driver with 3-state outputs. Key applications: buffering and isolating wide data/address buses in microprocessor/memory systems; interfacing between devices with different supply voltages; bus expansion and fan-out on FPGA/ASIC designs; backplane/inter-board data paths; high-speed data routing where tri-state control is required.

Equivalent

Possible drop-in equivalents (functionally the same 16-bit registered buffer/driver with 3-state outputs):
