Nexperia USA Inc. 74LV4051PW,112

Overview

74LV4051PW,112 from NXP Semiconductors is an 8-channel analog multiplexer/demultiplexer with CMOS logic-level compatibility, 100 Ω on-resistance (typ), ±5 V analog signal range, and 3.3 V supply operation. It serves as a bidirectional signal routing switch in mixed-signal interface circuits for data acquisition systems.

For engineers reviewing the 74LV4051PW,112 datasheet, 74LV4051PW,112 pinout, 74LV4051PW,112 application, or 74LV4051PW,112 equivalent, key selection criteria include channel count, on-resistance matching, break-before-make timing, supply voltage tolerance, and ESD rating for sensor front-end switching.

Technical Context

This device implements a single-pole octal-throw (SP8T) analog switch controlled by three binary address inputs (S0–S2) and an active-low enable input (/E). Internal level-shifting circuitry allows TTL/CMOS-compatible control logic while supporting ±5 V analog signals across all channels.

It features break-before-make switching to prevent channel shorting during state transitions, rail-to-rail analog signal handling, and guaranteed monotonic switching behavior over temperature and supply voltage variations from 1.0 V to 6.0 V.

FAQ

What is the maximum analog signal frequency supported by the 74LV4051PW,112?

The device supports analog signals up to 100 MHz bandwidth (–3 dB point) with typical on-capacitance of 40 pF and 100 Ω R_ON. This enables use in audio-band and low-speed data acquisition applications, but not RF or high-speed serial signal routing. Bandwidth remains stable across the full ±5 V signal range and 1.0–6.0 V supply range.

Does the 74LV4051PW,112 require external pull-up resistors on address or enable pins?

No external pull-ups are required. The S0–S2 and /E inputs have CMOS-compatible thresholds and internal input hysteresis. They accept clean TTL or CMOS logic levels directly from microcontrollers or FPGAs. Pull-ups may be added only if open-drain control sources are used, which is not typical in standard implementations.

Can the 74LV4051PW,112 be used with dual-supply configurations (e.g., ±5 V rails)?

No. The device operates from a single positive supply (V_CC) referenced to GND. Its analog I/O pins tolerate voltages from –5 V to V_CC + 0.5 V, enabling bipolar signal handling on a single 5 V or 3.3 V rail - no negative supply is needed or supported.

Is there a version of this part with latch-enable functionality?

No. The 74LV4051PW,112 uses combinational address decoding only. Latch-enable variants such as the 74LV4051B (with separate LE input) exist in the same family but are distinct orderable parts. The ,112 suffix denotes TSSOP-16 packaging and standard commercial temperature grade (–40 °C to +125 °C).
