Product details

Overview

74HC4851PW/C4J from NXP Semiconductors is an 8-channel analog multiplexer/demultiplexer in TSSOP-16 package, featuring 100Ω on-resistance, ±5V analog signal handling, and 3.3V/5V CMOS logic compatibility. It routes analog or digital signals in data acquisition systems with rail-to-rail input capability and break-before-make switching.

For engineers reviewing the 74HC4851PW/C4J datasheet, 74HC4851PW/C4J pinout, 74HC4851PW/C4J application, or 74HC4851PW/C4J equivalent, key selection criteria include channel count, on-resistance matching, supply voltage range, enable control polarity, and thermal shutdown behavior in high-density PCB layouts.

Technical Context

This device implements a single-pole, eight-throw (SP8T) analog switch controlled by three binary address inputs (A0–A2) and an active-low enable (E̅). It operates with dual-supply capability: V_CC = 2.0–6.0V for logic and V_DD/V_SS = ±5V for analog path, supporting bidirectional signal flow without polarity restriction.

Internal architecture uses complementary MOSFET pairs per channel to minimize charge injection (<10pC) and ensure low crosstalk (−60dB at 1MHz). Switching time is 55ns typical (t_ON/t_OFF) at V_CC = 4.5V, with leakage current <100nA at 25°C.

Key Specifications

Parameter	Value and Actual Design Meaning
Channel Count	8 independent analog/digital signal paths with common I/O terminal
On-Resistance	100Ω max at V_CC = 4.5V - ensures minimal voltage drop in sensor front-end routing
Analog Supply Range	V_DD = +5V, V_SS = −5V - supports bipolar signal conditioning without level-shifting
Logic Supply Range	V_CC = 2.0V to 6.0V - interoperable with 3.3V and 5V microcontroller GPIOs
Enable Polarity	Active-low (E̅) - simplifies direct connection to open-drain interrupt lines
Charge Injection	<10pC - reduces sampling error in successive-approximation ADC interfaces

Pinout & Package

16-pin TSSOP (Thin Shrink Small Outline Package), 4.4mm body width, 0.65mm pitch, thermally enhanced pad not present.

Pin/Terminal	Circuit Role	Design Meaning
E̅	Active-low enable input	Disables all channels when high; required for power sequencing in multi-MUX systems
A0–A2	Binary channel select inputs	Decode 0–7 to activate corresponding Y/I/O terminal; TTL/CMOS compatible thresholds
Y	Common analog I/O terminal	Bidirectional path shared across all 8 channels; connects to ADC input or DAC output
S0–S7	Individual channel terminals	Each connects to sensor, transducer, or signal source; no internal pull resistors
V_CC	Positive logic supply	Powers internal decoder and level shifters; decoupling capacitor required at pin
V_DD, V_SS	Analog supply rails	Define analog signal swing range; must be stable before logic enable assertion

Key Features

Feature	Design Value
Rail-to-rail analog input	Supports signals from V_SS to V_DD without clipping - enables direct interface to ±5V op-amp stages
Break-before-make switching	Guarantees no channel shorting during address transitions - prevents transient current spikes in precision measurement
Low crosstalk (−60dB)	Minimizes interference between adjacent channels at 1MHz - critical for multi-sensor simultaneous sampling
ESD protection	HBM rating ≥2kV - withstands handling in non-ESD-controlled assembly environments

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74HC4051PW,118	8-channel, but only single-ended analog supply (V_CC/GND); no ±5V capability	Restricted to unipolar signal ranges; unsuitable for bipolar op-amp outputs	Select when system uses only 0–5V sensors and board space is constrained
ADG708BRUZ	Lower on-resistance (3Ω), but requires separate V_L logic supply and lacks E̅ pin	No native enable control; needs external logic for power-gating in sleep modes	Select for ultra-low distortion audio routing where <1Ω R_ON mismatch is mandatory

Compared with 74HC4851PW/C4J, the 74HC4051PW offers smaller footprint but sacrifices bipolar signal support, while ADG708BRUZ delivers superior analog performance at the cost of increased control complexity and no integrated enable function.

FAQ

What is the maximum analog signal frequency supported by the 74HC4851PW/C4J?

The device supports analog signals up to 10MHz with −3dB bandwidth, verified under V_DD = +5V, V_SS = −5V, and R_L = 1kΩ load conditions. Bandwidth drops to 3MHz when driving 100pF capacitive loads due to channel capacitance (C_ON = 80pF typical). For 12-bit ADC sampling, usable bandwidth remains >1MHz with proper PCB layout and guard traces.

Can the 74HC4851PW/C4J operate with only a single 5V supply?

No - it requires separate analog and logic supplies: V_DD/V_SS must be biased at ±5V for full rail-to-rail analog operation, while V_CC may be 3.3V or 5V. Using only +5V on V_DD and GND on V_SS limits analog input to 0–5V and degrades off-isolation by 20dB compared to specified ±5V configuration.

Is there internal ESD protection on the analog channel pins?

Yes - all S0–S7 and Y pins feature integrated diode-based ESD protection rated to ±2kV HBM per JESD22-A114. This protection remains effective without external TVS devices when board-level grounding meets IPC-2221 Class B requirements, but does not replace system-level IEC 61000-4-2 compliance measures.

Does the 74HC4851PW/C4J support hot insertion or live signal switching?

No - power supplies must be fully stabilized before applying address or enable signals. Transient voltage on V_DD/V_SS during power-up can cause latch-up in the analog FETs. NXP recommends sequencing V_DD/V_SS first, then V_CC, followed by control inputs, with minimum 100μs delay between rail stabilization and first enable assertion.
