Description
Equivalent
- 74HC4051
- 74HCT4051
- CD4051B (CD4000 CMOS family)
- LF4051 / LF4051B (Fairchild)
- MC14051B (Motorola/On Semiconductor)
Note: these chips are functionally the same but choose one with the same supply voltage and signal ranges as your design (e.g., 2–6 V for VHC, etc.).
Features
- 8-channel multiplexer/demultiplexer with a single common I/O (COM)
- 3 select inputs (S1, S2, S3) plus an enable input (E)
- Break-before-make switching; low on-resistance (typical ~125 Ω at Vcc = 5 V)
- Wide supply range: Vcc = 2.0 V to 6.0 V
- Analog signal range up to Vcc (single-supply operation)
- Off-state leakage typically in the sub-μA range; low crosstalk
- CMOS technology: low static/dynamic power; TTL/CMOS input compatible
- Fast, predictable switching suitable for analog routing
- ESD protection and robust operation within rail limits
- Package options: 16-pin devices; AFT suffix indicates packaging variant (e.g., tape-and-reel)
Note: Exact parameters (Ron, leakage, ac characteristics) vary by vendor and process; consult the specific datasheet for precise numbers.
Pinout
- Function: 8-channel analog multiplexer/demultiplexer (8:1). A single common I/O pin connects to one of eight input/output pins (Y0–Y7) based on the 3 select inputs (A, B, C). Includes an INH (inhibit) input to disable all channels. Suitable for routing analog or digital signals within the supply voltage range (VCC).
Manufacturer
- About the company: Nexperia is a global semiconductor company that designs and manufactures standard logic, analog/mixed-signal ICs, discretes and related components (e.g., ESD protection). It originated from Philips/NXP’s semiconductor business and is headquartered in the Netherlands.
Application
- Data acquisition and instrumentation (multiplexing several sensors into one ADC/DAC)
- Sensor interfacing and MCU I/O expansion
- Audio/video signal routing and switching
- Programmable analog signal routing in consumer electronics
- Automotive/industrial control signal multiplexing
- Test equipment and signal routing (oscilloscopes, bench gear)
- Medical instrumentation for multiplexed sensor signals
