Frequently Asked Questions
What is the maximum operating frequency of the SN74LV166APWRG4?
The SN74LV166APWRG4 supports a maximum operating frequency of 35MHz at nominal supply voltage with a 50pF load capacitance. This high-speed operation makes it suitable for demanding serial data conversion applications in embedded and industrial systems.
What supply voltage range does the SN74LV166APWRG4 support?
As part of the LV-A logic family, the SN74LV166APWRG4 operates across a wide supply voltage range of 2V to 5.5V, making it compatible with both 3.3V and 5V logic systems. This flexibility simplifies interfacing in mixed-voltage designs without additional level translation.
What package does the SN74LV166APWRG4 use and is it RoHS compliant?
The SN74LV166APWRG4 is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package) and carries the G4 suffix indicating it is fully RoHS and REACH compliant with a lead-free, halogen-free construction. The compact 16-pin footprint is well suited for high-density PCB assemblies.
What are typical applications for the SN74LV166APWRG4?
This 8-bit PISO shift register is commonly used for reading arrays of switches, buttons, or sensor outputs into a microcontroller via SPI or bit-banged serial interfaces. It is also used in data logging equipment, industrial PLCs, and LED driver scan circuits where parallel digital states must be serialized.
How does the SN74LV166APWRG4 differ from the non-A variant SN74LV166?
The 'A' variant of the SN74LV166 offers improved electrical characteristics, including lower propagation delay and better noise immunity compared to the original SN74LV166. Both share the same 8-bit parallel-load shift register functionality and pin-compatible 16-pin TSSOP package, making the A version a drop-in performance upgrade.
