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.
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.
