Overview
The Nexperia 74HC4051PW,112 is a single-pole octal-throw (SP8T) analog switch manufactured using silicon gate CMOS technology. It functions as an 8-channel multiplexer or demultiplexer within a 16-pin TSSOP package. The device supports a wide analog input voltage range from -5 V to +5 V and operates with supply voltages between 2 V and 10 V. Key electrical characteristics include a maximum on-resistance of 180 Ohms, a propagation delay of up to 90 ns, and a bandwidth of 180 MHz. It features three digital select inputs, one low-active enable input, and eight independent I/Os. The component is rated for industrial temperatures ranging from -40 °C to +125 °C.
Feature Summary
- Provides bidirectional analog signal routing across eight independent channels controlled by binary select codes.
- Incorporates a 'break before make' switching mechanism to prevent signal shorting during channel transitions.
- Features clamp diodes on inputs to allow interfacing with voltages exceeding the positive supply rail when current-limiting resistors are used.
- Delivers high noise immunity and low power dissipation typical of CMOS logic families.
Applications
- Analog multiplexing and demultiplexing in data acquisition systems.
- Signal gating and routing in industrial control circuits.
- Digital multiplexing applications requiring level translation between logic domains.
Procurement Notes
Verify the specific suffix against manufacturer documentation, as the 74HC4051PW,112 variant may be subject to discontinuation status. Confirm availability through authorized distributors and check for active replacement part numbers if the original component is no longer in production. Ensure compliance with RoHS and REACH regulations relevant to the target market.
Selection Notes
Select this component for designs requiring an 8-channel analog switch with a wide operating voltage range and industrial temperature stability. Consider the 180 Ohm maximum on-resistance and 180 MHz bandwidth when evaluating signal integrity requirements. Verify that the TSSOP-16 package dimensions fit the PCB layout constraints and that the supply voltage aligns with the 2 V to 10 V operational limits.
Part Context
This device belongs to the standard 74HC series of high-speed CMOS logic components produced by Nexperia. It is functionally compatible with other manufacturers' 74HC4051 implementations, such as those from Texas Instruments or NXP. The PW suffix indicates the TSSOP16 package type, while the ,112 denotes the specific tape and reel packaging configuration defined by the manufacturer.
Replacement Considerations
The MC74HC4051ADTR2G from onsemi serves as a functional substitute offering similar 8-channel SP8T architecture in a 16-TSSOP package. Designers should verify pinout compatibility and compare on-resistance specifications, as the alternative may exhibit different electrical performance metrics under identical load conditions.
