The MM74C174N hex D 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:
Wide supply voltage range 3.0V to 15V
Guaranteed noise margin 1.0V
High noise immunity 0.45 VCC (typ.)
Low power TTL compatiblity

16 pin DIP. Manufactured by National.
