The TC74VHC393FT is a dual 4-stage binary ripple counter manufactured by Toshiba Semiconductor and Storage. It belongs to the Very High-Speed CMOS (VHC) logic family, providing high-speed operation with low power consumption. The 'FT' suffix typically indicates a TSSOP (Thin Shrink Small Outline Package), which is a compact surface-mount package. This device contains two independent 4-stage binary counters, each with its own clock and reset inputs.
