1 / 21 page SN54AHC273, SN74AHC273 OCTAL D-TYPE FLIP-FLOPS WITH CLEAR SCLS376G – JUNE 1997 – REVISED JULY 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Operating Range 2-V to 5.5-V VCC 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 D Latch-Up Performance Exceeds 250 mA Per JESD 17 D ESD Protection Exceeds JESD 22 – 2000-V Human-Body Model (A114-A) – 1000-V Charged-Device Model (C101) description/ordering information These circuits are positive-edge-triggered D-type flip-flops 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 directly related 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.
