Overview
The Nexperia 74HC2G66GD,125 is a dual single-pole single-throw analog switch housed in an SOT996-2 (XSON8) package. It features two independent bidirectional switches with active HIGH enable inputs and input clamp diodes. The device operates on a wide supply voltage range from 2.0 V to 10.0 V. Typical ON resistance values are 41 Ω at 4.5 V, 30 Ω at 6.0 V, and 21 Ω at 9.0 V. Propagation delay ranges from 10 ns to 15 ns depending on the supply voltage. The component supports an ambient temperature range of -40 °C to +125 °C.
Feature Summary
- Dual SPST analog switch configuration with bidirectional signal paths
- Wide supply voltage operation up to 10.0 V for HC logic family
- Input terminals include clamp diodes for overvoltage protection
- High noise immunity and robust latch-up performance
Applications
- Signal routing in mixed-signal systems
- Audio and video signal switching
- Data acquisition multiplexing
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current product data sheet to confirm the package type and availability status. Ensure that the procurement channel provides original manufacturer documentation to validate authenticity and traceability before finalizing any purchase orders.
Selection Notes
Select this component when a dual-channel analog switch is required with a supply voltage capability exceeding standard 5.5 V limits. The HC logic family is appropriate for applications requiring CMOS input levels across a broad voltage spectrum. Verify that the maximum ON resistance at the target operating voltage meets the signal integrity requirements of the application.
Part Context
This part belongs to the Nexperia 74HC/HCT2G series of compact analog switches. These devices are designed for space-constrained applications utilizing small outline packages. The 74HC variant specifically targets wider voltage ranges compared to the HCT version, which is limited to TTL-compatible levels.
Replacement Considerations
The 74HCT2G66GD,125 serves as a functional replacement if the application operates strictly within the 4.5 V to 5.5 V supply range and requires TTL-compatible input thresholds.
