SN74LV8156PWR-P is listed in the Counter Dividers range at ChipApex. The manufacturer field lists Texas Instruments. Its product description is PROTOTYPE. Review the specifications below when checking this part for your BOM.
The SN74LV8156PWR-P is a prototype binary counter IC from Texas Instruments, utilizing LV logic series technology. It features a 16-bit configuration with two internal circuits housed in a TSSOP-20 package for surface-mount installation. The device operates as an up-counter triggered by rising edges, supporting unidirectional counting. It functions within a supply voltage range of 2 V to 5.5 V and withstands operating temperatures from -40 °C to +85 °C.
Verify the prototype designation (suffix -P) carefully before procurement, as it indicates non-standard manufacturing status. Confirm current availability through official TI channels or authorized distributors, as prototype parts may have limited supply or discontinuation risks. Ensure the TSSOP-20 package matches your PCB footprint requirements.
Select this component only if a 16-bit binary counter with LV logic compatibility is required. Verify that the 2 V to 5.5 V operating voltage range aligns with your system power rails. Consider the TSSOP-20 package constraints for your assembly process. Note that the prototype status may affect long-term supply stability compared to standard commercial variants.
This part belongs to Texas Instruments' LV logic family, designed for low-voltage applications. Unlike standard production counters, the -P suffix denotes a prototype unit, which typically lacks full commercial qualification documentation. It serves niche development needs rather than mass production environments.
Public confirmed substitute: SN74HCS595DYYR.
