Overview
The TC74HC4051APF is an 8-channel analog/digital multiplexer and demultiplexer manufactured by Toshiba Semiconductor and Storage. It belongs to the 74HC series of CMOS logic integrated circuits, designed for high-speed signal routing applications. The device operates within a supply voltage range of 2.0 V to 6.0 V and supports a propagation delay of 15 ns. It features three address inputs to select one of eight channels and includes an enable input for controlling data flow. The component is housed in a 16-pin DIP package suitable for through-hole mounting.
Feature Summary
- Provides bidirectional switching capability for eight independent channels controlled by three binary address lines.
- Integrates an active-low enable function to isolate the selected channel from the common terminal when deactivated.
- Utilizes advanced silicon gate technology to ensure low power consumption and robust noise immunity.
Applications
- Data acquisition systems requiring sequential sampling of multiple sensor inputs.
- Audio signal routing and mixing circuits for consumer electronics.
- Communication equipment utilizing time-division multiplexing architectures.
Procurement Notes
Verify the specific suffix APF confirms the 16-pin Dual In-line Package (DIP) configuration during sourcing. Confirm RoHS compliance status with the supplier as environmental regulations vary by region. Ensure the ordering quantity matches the standard tube packaging format typically associated with this package style. Cross-reference the manufacturer part number against distributor databases to avoid obsolete or alternate variant confusion.
Selection Notes
Select this component when a through-hole DIP footprint is required for prototyping or legacy board designs. Compare the 15 ns propagation delay against system timing requirements to ensure adequate speed margins. Evaluate the 2.0 V to 6.0 V operating range against available power rails to confirm compatibility. Consider alternative surface-mount packages if PCB space constraints preclude the use of DIP components.
Part Context
This part is a member of the widely adopted 74HC family of logic ICs, known for compatibility with standard TTL logic levels while offering improved performance over older NMOS technologies. The TC prefix denotes Toshiba's commercial grade manufacturing line. It serves as a functional equivalent to other industry-standard 8-channel multiplexer ICs within the same voltage and speed class.
Replacement Considerations
Direct substitutes include the SN74HC4051 from Texas Instruments and the MC74HC4051 from onsemi. Verify pinout compatibility and electrical specifications such as on-resistance and leakage current before substitution. Ensure the replacement package type matches the existing board layout constraints.
