概述

Description

SN74LV4051ARGYR is a TI low‑voltage, 8‑channel analog multiplexer/demultiplexer. It has one common port (Z) and eight data ports (Y0–Y7). Three binary select inputs (S1, S2, S3) choose which Yn is connected to Z, while an enable input can tri-state Z for high‑impedance. The device accepts analog or digital signals within the supply rails and is suitable for signal routing, multiplexing in data acquisition, instrumentation, audio routing, and other low‑power applications. The LV family indicates low‑voltage CMOS operation with modest on‑resistance (a few hundred ohms) and low leakage. The ARGYR suffix denotes a specific TI package/order option (typical 8‑pin package with TI’s standard packaging, e.g., tape‑and‑reel). For exact electrical specs (VCC range, Ron, leakage, timing), refer to the SN74LV4051A datasheet.

Features

Here are the key features of SN74LV4051ARGYR:
- 8-channel single 1-of-8 multiplexer/demultiplexer (I0–I7 to common Z)
- 3 select inputs (S1, S2, S3) for channel selection
- Enable input (E) to disable all switches; Z becomes high-impedance when enabled
- Wide supply range: 1.65 V to 5.5 V (low-voltage CMOS)
- Signals can be analog or digital, within the supply range
- Bidirectional/bi-directional switching with low on-resistance
- Low power consumption and fast switching
- CMOS/TTL-compatible input thresholds
- Pb-free (RoHS) packaging option (ARGYR)

Package

SN74LV4051ARGYR comes in a 16-pin small-outline package (TSSOP‑16), RoHS compliant.

Pinout

- Pin count: 16 pins (16‑pin package, e.g., SOIC/DIP).
- Function: 8-channel analog multiplexer/demultiplexer. It connects one of eight analog inputs to a common I/O line under control of three select lines (A, B, C) with an active-high inhibit to disable all channels.

Manufacturer

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

Application

SN74LV4051ARGYR is an 8-channel, single-ended analog multiplexer/demultiplexer. Typical applications:
- Multiplex eight analog signals to one ADC input (or demultiplex one signal to eight outputs) in data acquisition and instrumentation.
- Route low-level audio/video or sensor signals in low-voltage portable electronics.
- Expand MCU I/O and build switch networks, keyboard scanners, test gear, and general signal routing on a single supply.
