Overview
The SN74HC4066PWT is a quad bilateral analog switch manufactured by Texas Instruments, housed in a 14-pin TSSOP surface-mount package. It operates on a single supply voltage ranging from 2V to 10V. Key electrical parameters include a maximum on-resistance of 70 Ohms and a bandwidth of 200MHz. The device features a propagation delay of 12ns (max) and an off-state leakage current of 100nA (max). It supports an operating temperature range from -55°C to +125°C and includes input clamp diodes for protection.
Feature Summary
- Quad bilateral switching configuration with four independent SPST channels
- High-speed CMOS logic compatible with standard TTL loads
- Wide single-supply voltage operation capability
- Integrated input clamp diodes for overvoltage protection
Applications
- Analog signal routing and gating
- Audio and video signal switching
- Data acquisition systems
- Battery management circuits
Procurement Notes
Verify the specific suffix 'PWT' confirms the TSSOP-14 package and tape-and-reel packaging format. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding pinout or material changes. Ensure the supplier provides valid traceability documentation for the component lot.
Selection Notes
Select this component when a compact surface-mount solution is required for low-voltage analog switching applications. Compare the 70 Ohm on-resistance against system signal integrity requirements. Consider the extended industrial temperature range if operation exceeds standard commercial limits. Verify that the 2V minimum supply voltage aligns with the target system power rails.
Part Context
This part belongs to the SN74HC series of high-speed CMOS logic devices. It is functionally equivalent to other 74HC4066 variants but specifies the TSSOP-14 physical footprint. The 'SN' prefix denotes Texas Instruments manufacturing standards. It serves as a digital-controlled analog switch within mixed-signal circuit designs.
Replacement Considerations
Direct substitutes include CD74HC4066PWR and CD74HC4066PWT. Cross-manufacturer equivalents such as MC74HC4066ADTR2G may require verification of pin compatibility and electrical parameter tolerances before implementation.
