MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC54/74HC174A Hex D Flip-Flop with Common Clock and Reset High–Performance Silicon–Gate CMOS J SUFFIX CERAMIC PACKAGE The MC54/74HC174A is identical in pinout to the LS174. The device 16 CASE 620–10 inputs are compatible with standard CMOS outputs; with pullup resistors, 1 they are compatible with LSTTL outputs. This device consists of six D flip–flops with common Clock and Reset inputs. Each flip–flop is loaded with a low–to–high transition of the Clock N SUFFIX input. Reset is asynchronous and active–low.
