MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC54/74HC175A Product Preview Quad D Flip-Flop with Common Clock and Reset J SUFFIX CERAMIC PACKAGE High–Performance Silicon–Gate CMOS 16 CASE 620–10 1 The MC54/74HC175A is identical in pinout to the LS175. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. N SUFFIX This device consists of four D flip–flops with common Reset and Clock PLASTIC PACKAGE inputs, and separate D inputs. Reset (active–low) is asynchronous and 16 CASE 648–08 occurs when a low level is applied to the Reset input. Information at a D input 1 is transferred to the corresponding Q output on the next positive going edge of the Clock input. • Output Drive Capability: 10 LSTTL Loads D SUFFIX
