MC14043BDG

The MC14043BDG quad R-S latch integrates four Set-Reset latch cells that provide simple state retention useful in debouncing, interlocking, and small control systems. Each latch holds its output state until an input changes it, enabling straightforward memory elements for handshaking circuits, button interfaces, and simple finite-state controls without using microcontrollers. The device’s CMOS thresholds and timing characteristics make it suitable for reliable operation within standard logic environments. Its SMD form factor supports compact board layouts and automated soldering, which benefits both production runs and repair work. Florida Circuit stocks authenticated components, provides datasheets, and offers fast fulfillment to help you confirm timing behavior and input polarity prior to assembly.
