Overview
The MC74VHC1G66DTT1 is a single-channel SPST normally open analog switch manufactured by onsemi. It operates within a supply voltage range of 2 V to 5.5 V and features a maximum on-resistance of 40 Ohms. The device supports high-speed signal switching with a bandwidth of 180 MHz and propagation delays of 25 ns for both rise and fall times. It utilizes a TSOP-5 surface-mount package and functions reliably across an extended temperature range from -55°C to +125°C.
Feature Summary
- Single-channel SPST normally open configuration for precise signal routing
- High-speed performance with 180 MHz bandwidth and 25 ns switching times
- Low on-resistance of 40 Ohms ensures minimal signal attenuation
- Extended industrial temperature operation up to 125°C
Applications
- Portable equipment requiring low-voltage signal switching
- Battery-powered systems utilizing 2V to 5.5V supplies
- Industrial control applications operating in extreme temperatures
- Communication devices needing high-bandwidth analog routing
Procurement Notes
Verify component authenticity through authorized distributors due to potential counterfeits. Confirm RoHS compliance status as historical data indicates non-compliance for specific variants. Check manufacturing date codes against current inventory requirements. Ensure the TSOP-5 package matches PCB footprint specifications before ordering.
Selection Notes
Select this component when a single-channel analog switch with low on-resistance is required. Compare propagation delay specifications against system timing constraints. Verify that the 2V minimum supply voltage aligns with the target application's power rails. Consider the TSOP-5 package size for space-constrained designs.
Part Context
This part belongs to the MC74VHC1G series of single-gate CMOS logic and analog switches. It shares functional similarities with other single-channel switches in the family but offers specific speed and resistance characteristics tailored for high-performance analog applications.
Replacement Considerations
The MC74VHC1G66DTT1G is a verified lead-free variant of this component. Other similar parts include the MC74VHC1GT66 series. Verify pin compatibility and electrical parameters before substituting.
