This device is a programmable frequency divider and has two clock inputs, either one may be used for clock gating. (see the function table). The M74HC292 can divide from 22 to 231. This device feature an active-low clear input to initialize the state of all flip-flops. To facilitate incoming inspection, test points (TP1, TP2, TP3) are provided. All inputs are equipped with protection circuits against static discharge and transient excess voltage. This device has Q output with "Totem Pole" configuration and test point TP with "Open Drain" output configuration.
