The MC54/74HC174A is identical in pinout to the LS174. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
MC54/74HC174A consists of six D flipflops with common Clock and Reset inputs. Each flipflop is loaded with a lowtohigh transition of the Clock input. Reset is asynchronous and activelow.
