Product details
Overview
74HC4051DB,112 from Nexperia is an 8-channel analog multiplexer/demultiplexer (SP8T) with CMOS logic interface, ±5 V analog signal handling capability, 60–100 Ω typical ON resistance at 4.5–9.0 V supply, and -40 °C to +125 °C operation. It routes analog or digital signals in data acquisition systems, sensor interface modules, and test equipment where bidirectional signal switching and logic-level translation are required.
For engineers reviewing the 74HC4051DB,112 datasheet, 74HC4051DB,112 pinout, 74HC4051DB,112 application, or 74HC4051DB,112 equivalent, this device supports high-fidelity analog multiplexing with low crosstalk (<220 mV), <10 ns turn-on time at 4.5 V/–4.5 V supplies, and rail-to-rail analog voltage range (–5 V to +5 V) - critical for precision instrumentation and mixed-signal embedded designs.
Technical Context
The 74HC4051DB,112 implements a single-pole octal-throw (SP8T) analog switch architecture controlled by three binary select inputs (S0–S2) and an active-low enable (E). Its internal decoder activates exactly one of eight Yn–Z paths per selection code, with built-in 'break-before-make' timing to prevent channel shorting.
It operates with dual supplies (VCC and VEE), enabling true bipolar analog signal routing (e.g., ±5 V), while maintaining TTL-compatible logic thresholds on control pins. Clamp diodes on all inputs allow safe interfacing to voltages beyond VCC when used with current-limiting resistors.

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 | TSSOP16 package (4.4 mm width); identical electrical specs and pinout | Higher board density; better thermal performance in compact layouts | Select when footprint reduction or improved heat dissipation is required |
| ADG708BRUZ | Single-supply only (1.8–5.5 V); no VEE pin; 3.5 Ω typical RON; SPI interface | Not suitable for bipolar analog signals; requires digital control bus instead of parallel address lines | Choose only for low-voltage, unipolar, digitally controlled applications - not drop-in compatible |
Compared with 74HC4051PW,118, the 74HC4051DB,112 offers identical functionality in a wider SOIC package suited for prototyping and through-hole-compatible reflow; versus ADG708BRUZ, it provides true dual-supply operation and parallel addressing but higher RON, making it optimal for cost-sensitive, bipolar-signal routing where SPI overhead is undesirable.

FAQ
What is the maximum analog signal voltage range supported by the 74HC4051DB,112?
The 74HC4051DB,112 supports an analog input voltage range from –5 V to +5 V relative to its VEE and VCC rails. This is achieved using dual supplies (e.g., VCC = +5 V, VEE = –5 V), enabling true bipolar signal routing without external level-shifting circuitry - a key capability confirmed in the datasheet's General Description and Table 5.
Does the 74HC4051DB,112 include built-in protection against overvoltage on its analog inputs?
Yes, the 74HC4051DB,112 integrates clamp diodes on all Yn and Z pins. When used with appropriate current-limiting resistors, these diodes safely shunt voltages exceeding VCC or falling below VEE, allowing direct interfacing with signals up to ±20 V - as specified in Table 4 (Limiting Values) and Section 1 (General Description).
What is the typical ON resistance of the 74HC4051DB,112 and how does it vary with supply voltage?
The 74HC4051DB,112 exhibits 60 Ω typical ON resistance at VCC–VEE = 9.0 V, 70 Ω at 6.0 V, and 80 Ω at 4.5 V (Table 6). This inverse relationship reflects reduced channel conductivity at lower supply headroom - critical for minimizing insertion loss in precision analog paths.
Can the 74HC4051DB,112 be used in a single-supply configuration?
Yes, the 74HC4051DB,112 operates with VEE tied to GND (0 V), enabling single-supply use from 2.0 V to 10.0 V. In this mode, the analog range is 0 V to VCC, and logic thresholds remain CMOS-compatible - verified in Table 5 (Recommended Operating Conditions) and Figure 5 (Operating Area).
Is the 74HC4051DB,112 pin-compatible with other packages in the same family?
Yes, the 74HC4051DB,112 (SO16/SOT109-1) shares identical pinout and function with 74HC4051PW,118 (TSSOP16), 74HC4051BQ,115 (DHVQFN16), and 74HC4051BZ,115 (DHXQFN16), as confirmed in Section 6.1 (Pinning Information) and Table 1 (Ordering Information) of the datasheet.
