1 / 12 page SN74HC273Q1 OCTAL DTYPE FLIPFLOP WITH CLEAR SCLS578A − MARCH 2004 − REVISED APRIL 2008 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Qualified for Automotive Applications D Wide Operating Voltage Range of 2 V to 6 V D Outputs Can Drive Up To 10 LSTTL Loads D Low Power Consumption, 160-µA Max ICC D Typical tpd = 13 ns D ±4-mA Output Drive at 5 V D Low Input Current of 1 µA Max D Contain Eight Flip-Flops With Single-Rail Outputs D Direct Clear Input D Individual Data Input to Each Flip-Flop D Applications Include: − Buffer/Storage Registers − Shift Registers − Pattern Generators description/ordering information This circuit is a positive-edge-triggered D-type flip-flop with a direct clear (CLR) input. Information at the data (D) inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a particular voltage level and is not related directly to the transition time of the positive-going pulse. When CLK is at either the high or low level, the D input has no effect at the output.
