Overview
The Nexperia 74HC2G66DP,125 is a dual single-pole single-throw analog switch housed in an SOT505-2 (TSSOP8) package. It operates on a supply voltage range of 2.0 V to 10.0 V with an ambient temperature specification from -40 °C to +125 °C. The device features very low ON resistance, typically 41 Ω at 4.5 V and 30 Ω at 6.0 V. Static characteristics include input leakage current up to ±0.2 μA at 9.0 V and OFF-state leakage up to 1.0 μA. Dynamic performance specifies propagation delay maximums of 15 ns at 4.5 V and 14 ns at 6.0 V.
Feature Summary
- Dual SPST analog switch configuration with independent enable inputs
- Wide supply voltage capability extending up to 10.0 V
- Low ON resistance for efficient signal transmission
- High noise immunity and robust latch-up protection
Applications
- Signal routing in mixed-signal systems
- Audio and video signal switching
- Data acquisition multiplexing
Procurement Notes
Verify the specific ordering code 74HC2G66DP,125 against the latest Nexperia product data sheet to confirm availability and compliance with current environmental directives. Ensure that the TSSOP8 package variant matches the design requirements for thermal dissipation and board space constraints before finalizing procurement orders.
Selection Notes
Select this component when high-voltage analog signal switching is required within a compact footprint. The HC logic family provides compatibility with standard CMOS levels across a wide voltage range. Consider the ON resistance variation relative to the specific supply voltage and load current to ensure signal integrity meets application thresholds.
Part Context
This part belongs to the Nexperia 74HC/HCT2G66 series of dual analog switches. It shares functional similarities with other members like the 74HCT2G66DP but differs in logic threshold specifications. The DP suffix denotes the TSSOP8 plastic thin shrink small outline package, distinguishing it from VSSOP or XSON variants within the same logical family.
Replacement Considerations
Direct replacements include the 74HCT2G66DP,125 for TTL-compatible logic levels. Other package options such as 74HC2G66DC (VSSOP8) or 74HC2G66GT (XSON8) offer identical electrical functionality with different physical footprints.
