MM74C174 Hex D-Type Flip-Flop
October 1987 Revised January 1999
MM74C174 Hex D-Type Flip-Flop
General Description
The MM74C174 hex D-type flip-flop is a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement transistors. All have a direct clear input. Information at the D inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock pulse. Clear is independent of clock and accomplished by a low level at the clear input. All inputs are protected by diodes to VCC and GND.
Features
s Wide supply voltage range: s Guaranteed noise margin: s High noise immunity: 3.0V to 15V 1.0V 0.45 VCC (typ.)
s Low power TTL compatibility: Fan out of 2 driving 74L
Ordering Code:

Note 1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. Except for "Operating Temperature Range" they are not meant to imply that the devices should be operated at these limits. The Electrical Characteristics table provides conditions for actual device operation.
