MC74HC174A
Hex D Flip−Flop with
Common Clock and Reset
High−Performance Silicon−Gate CMOS
The MC74HC174A 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.
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 input. Reset is asynchronous and active−low.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
1. IO absolute maximum rating must be observed.
2. Tested to EIA/JESD22−A114−A.
3. Tested to EIA/JESD22−A115−A.
4. Tested to JESD22−C101−A.
5. Tested to EIA/JESD78.
6. For high frequency or heavy load considerations, see the ON Semiconductor High−Speed CMOS Data Book (DL129/D).
