Outputs are non-inverted, triggered on the positive clock edge. Quiescent current is 4 µA typical, output drive is 6.8 mA sink and source. Input capacitance is 5 pF. The 16-pin PDIP (0.300\" body) is a through-hole footprint that mates with standard DIP sockets or wave-solder boards.","metaTitle":"CD40174BE D-Type Flip-Flop, 4000B Series, 16 MHz, 16-PDIP","metaDescription":"CD40174BE D-type flip-flop, 4000B series, 16 MHz clock, 3V~18V supply, -55°C to 125°C, 16-PDIP.
