Product details
Overview
74HC4051N,652 from NXP Semiconductors is an 8-channel analog multiplexer/demultiplexer in a 16-pin DIP package, operating from 2.0 V to 10.0 V supply (VCC–GND), supporting ±5 V analog signal swing (VCC–VEE ≤ 10.0 V), with typical ON resistance of 80 Ω at 4.5 V and built-in break-before-make switching. It serves as a bidirectional analog signal router in data acquisition front-ends.
For engineers reviewing the 74HC4051N,652 datasheet, 74HC4051N,652 pinout, 74HC4051N,652 application, or 74HC4051N,652 equivalent, this device is selected for precision analog channel selection where rail-to-rail signal handling, low leakage (<±0.1 µA OFF-state), and TTL-compatible digital control are required in industrial sensor interfaces and test equipment.
Technical Context
The 74HC4051N,652 implements a 3-bit binary decoder driving eight transmission-gate switches between independent Y0–Y7 terminals and common Z, with active-low enable (E) controlling global switch state. Its CMOS transmission-gate architecture enables bidirectional analog conduction without polarity restriction.
Digital inputs S0–S2 and E operate over the full VCC range (2.0–10.0 V), while analog paths support voltage ranges from VEE to VCC - enabling operation with split supplies (e.g., VCC = +5 V, VEE = –5 V) or single-ended configurations (VEE = GND). The device features inherent logic-level translation between 5 V digital control and ±5 V analog domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC–GND) | 2.0 V to 10.0 V - supports battery-powered and industrial 5 V/9 V systems without level-shifting. |
| Analog Voltage Range | –5 V to +5 V - enables direct interfacing with bipolar op-amp stages and legacy instrumentation signals. |
| ON Resistance (RON) | 80 Ω typical at VCC=4.5 V, VEE=0 V - ensures minimal signal attenuation and gain error in 12-bit ADC front-ends. |
| OFF-State Leakage | ±0.1 µA max per channel at Tamb=25 °C - preserves accuracy in high-impedance sensor multiplexing (e.g., thermocouples). |
| Turn-On Time (ton) | 29 ns typical (VCC=4.5 V, VEE=0 V) - supports multiplexing rates up to ~17 MHz in time-division sampling systems. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial control environments. |
| ESD Protection | HBM >2000 V - reduces risk of field failure during PCB handling and system integration. |
Pinout & Package
74HC4051N,652 uses a plastic dual in-line package (DIP16, SOT38-4) with 300-mil lead spacing, through-hole mounting, and industry-standard pin layout compatible with breadboards and prototyping PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 2, 4, 13, 14, 15, 12 | Y0–Y7 | Independent analog I/O channels - each connects bidirectionally to Z when selected; no internal pull-up/down. |
| 3 | Z | Common analog I/O terminal - routes selected Yn signal; must be externally biased within VEE–VCC range. |
| 6 | E | Active-low enable - all switches OFF (high-Z) when HIGH; overrides S0–S2 state. |
| 9, 10, 11 | S0, S1, S2 | 3-bit binary select inputs - determine which Yn connects to Z (L/L/L = Y0, H/H/H = Y7). |
| 7 | VEE | Negative supply rail - sets lower analog voltage limit; may be tied to GND for unipolar operation. |
| 8 | GND | Digital ground reference - separate from VEE unless explicitly connected; decoupling critical for noise immunity. |
| 16 | VCC | Positive supply rail - powers digital logic section and defines upper analog limit; requires local 100 nF ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Wide analog voltage range | –5 V to +5 V operation with VCC–VEE ≤ 10.0 V - eliminates external level shifters in mixed-signal systems. |
| Low and matched ON resistance | 80 Ω typical (4.5 V), ΔRON ≤ 9 Ω - minimizes channel-to-channel gain mismatch in multi-sensor measurement arrays. |
| Break-before-make switching | Guaranteed internal timing - prevents momentary shorting between Yn channels during selection transitions. |
| Logic-level translation | 5 V digital inputs control ±5 V analog paths - simplifies interface between microcontrollers and bipolar signal chains. |
| High-temperature rating | Specified from –40 °C to +125 °C - supports deployment in engine control units and motor drives without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD74HC4051E | Same pinout and function; TI version rated only to +85 °C (vs. +125 °C for 74HC4051N,652); RON 90 Ω typical at 4.5 V. | Preferred for commercial-grade consumer electronics; not recommended for under-hood or industrial enclosures. | Select when ambient temperature stays below 85 °C and TI supply chain preference applies. |
| SN74LV4051A | Lower VCC range (2.0–5.5 V); RON 50 Ω typical at 5 V; supports 1.8 V logic inputs but no VEE pin - unipolar only. | Optimized for low-voltage portable systems; lacks bipolar analog support and high-temp qualification. | Choose for battery-powered devices requiring 1.8 V MCU compatibility and reduced power, but not for ±5 V signal routing. |

FAQ
What is the maximum allowable VCC–VEE differential for the 74HC4051N,652?
The 74HC4051N,652 specifies a maximum VCC–VEE differential of 10.0 V. Exceeding this limit risks permanent damage to the internal transmission gates. For example, if VCC = +9 V, VEE must be ≥ –1 V; if VEE = –5 V, VCC must be ≤ +5 V. This constraint is strictly enforced in both static and dynamic operation.
Can the 74HC4051N,652 operate with VEE = GND in a 3.3 V system?
Yes - the 74HC4051N,652 supports VEE = GND in 3.3 V systems. With VCC = 3.3 V and VEE = GND, the analog input range becomes 0 V to 3.3 V, and digital inputs S0–S2/E remain fully compatible. RON increases to ~120 Ω typical, and propagation delay extends to ~12 ns, both within datasheet specifications.
Does the 74HC4051N,652 require external pull-up resistors on its digital control pins?
No - the 74HC4051N,652 has CMOS inputs with negligible DC leakage (±0.1 µA max), so external pull-ups are unnecessary unless needed for system-level noise immunity or bus contention. Internal input structure does not rely on external biasing; direct connection to MCU GPIO is fully supported.
How does the break-before-make behavior manifest in the 74HC4051N,652 timing?
The 74HC4051N,652 guarantees break-before-make via internal decoder timing: the previously selected switch turns OFF before the newly selected switch turns ON. Measured turn-off time (toff) is faster than turn-on time (ton) under identical conditions - e.g., 31 ns vs. 29 ns at VCC = 4.5 V - ensuring no overlap conduction between Yn channels.
Is the 74HC4051N,652 pin-compatible with the 74HCT4051N variant?
Yes - the 74HC4051N,652 is pin-compatible with the 74HCT4051N, sharing identical pinout, package (DIP16), and functional block diagram. However, the 74HCT4051N uses TTL-compatible input thresholds (VIH = 2.0 V min) and is limited to 4.5–5.5 V VCC, whereas the 74HC4051N,652 supports 2.0–10.0 V with CMOS thresholds.
