SN74190N BCD counter: precise counting, TTL logic.

SN74190N is a TTL synchronous up/down BCD counter designed for accurate decimal counting. It counts from 0 to 9 in both directions and changes state on the clock edge, which helps reduce timing errors. Preset inputs allow the SN74190N to load a specific count when needed, giving better control in sequencing and timing circuits. The device runs on a standard 5 V supply and comes in a through-hole DIP package for easy board assembly. Engineers use SN74190N in counters, timers, and digital control panels where predictable behavior matters. Choose SN74190N from Florida Circuit to support reliable designs.
