Dual 4-bit binary ripple counter — logic family fit
The 74LV393D,112: This is a dual 4-bit binary ripple counter from NXP's 74LV family, operating at a lower supply voltage than the 74HC series while maintaining CMOS logic compatibility. It counts input pulses and outputs a binary representation on four parallel lines per counter. The Bulk package means it ships as individual units, not on tape-and-reel — relevant if your pick-and-place line expects reeled parts or if you are hand-loading prototypes.
How it compares to the 74HC390D,652
The 74HC390D,652 is a dual decade counter (divide-by-2 and divide-by-5), while the 74LV393D,112 is a dual 4-bit binary counter (divide-by-16). They are not pin-compatible drop-ins — the logic function and pinout differ, so a board designed for one will not accept the other without a layout change.
