M74HC173
DESCRIPTION
The M74HC173 is an high speed CMOS QUAD D-TYPE REGISTER (3-STATE) fabricated with silicon gate C2MOS technology. This device is posed of a four-bit register including D-TYPE flip-flops and 3-state buffers. The four flip-flops are controlled by a mon clock input (CLOCK) and a mon reset input (CLEAR). Signals applied to the data inputs (D1 D4) are stored at the respective flip-flops on the positive going transition of the clock input, only

M74HC173RM13TR M74HC173TTR when both clock control inputs (G1 and G2) are held low. The reset feature is asynchronous and active high. The stored data are provided on each output only when both output control inputs (M and N) are held low, otherwise the outputs go to the high-impedance state. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
