概述

Description

The 74VHC4051AFT is an 8-channel, single-pole, 8-throw analog multiplexer/demultiplexer in the 74VHC CMOS family. It uses three select inputs (S0, S1, S2) to connect the common I/O (often labeled Z) to one of eight I/O pins (X0–X7). An INH (inhibit) input can disconnect all channels. The device is bidirectional, so signals (analog or digital) can pass either direction within the supply rails. Typical supply range is 2–6 V (Vcc) for VHC parts, with leakage and on-resistance suitable for signal routing in test, measurement, or control circuits. Applications include signal routing, multiplexing sensors, data acquisition, and programmable routing in microcontroller projects. The “AFT” suffix denotes a specific packaging/ordering variant (check datasheet for exact package and tape-and-reel details). Always ensure input levels stay within Vcc and do not exceed rail limits to avoid damage.

Features

Key features of 74VHC4051AFT:
- 8-channel analog multiplexer/demultiplexer (1-of-8) with a common I/O (Z) and eight I/O channels (X0–X7)
- 3 binary select inputs (A, B, C) to choose the active channel
- Single-supply operation: Vcc in the 2V–6V range (74VHC family)
- Analog signal path within 0–Vcc range; suitable for analog and digital signals
- Low on-resistance when on and high off-isolation (low leakage in off state)
- Bidirectional analog switching; flexible for routing signals in either direction
- Fast switching suitable for typical logic/analog applications
- Low power consumption and wide operating temperature range (industrial/-40°C to 125°C)
- Available in surface-mount packages (e.g., 16-pin) with standard tape & reel options
Note: For exact electrical specs (Ron, Ioff, TS, packaging), refer to the latest datasheet for the AFT variant.

Package

74VHC4051AFT comes in a 16‑pin surface‑mount package (SOIC‑16, Pb‑free/RoHS).

Pinout

- Pin count: 16 pins (16-pin package, e.g., DIP16/SO16 in the AFT variant).
- Function: 8-channel analog multiplexer/demultiplexer. One of eight inputs (X0–X7) is connected to a single common I/O pin (Z) under control of three select inputs (A, B, C). An enable input can disable all channels. Used to route analog signals to/from one ADC or DAC.

Manufacturer

- Manufacturer: Nexperia
- What kind of company: A global semiconductor company that designs and manufactures standard logic, discrete, and analog components (spun off from Philips/NXP; headquartered in the Netherlands).

Application

- 8-channel analogue multiplexer/demultiplexer (one common I/O; 3 select lines)
- Route eight analog signals to a single ADC/DAC or to eight destinations
- Data acquisition and sensor multiplexing to reduce channel count
- Instrumentation, test equipment, and signal routing
- Audio/low-frequency video signal routing in consumer electronics
- Microcontroller I/O expansion for analogue signals
- General DC to low-frequency analogue/digital signal switching with low on-resistance
