74VHC374 Octal D-Type Flip-Flop with 3-STATE Outputs April 2007 74VHC374 Octal D-Type Flip-Flop with 3-STATE Outputs Features ■ High Speed: tPD = 5.4ns (typ) at VCC = 5V ■ High noise immunity: VNIH = VNIL = 28% VCC (Min.) ■ Power down protection is provided on all inputs ■ Low power dissipation: ICC = 4µA (Max) @ TA = 25°C ■ Pin and function compatible with 74HC374 tm General Description The VHC374 is an advanced high speed CMOS octal flip-flop with 3-STATE output fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This 8-bit D-type flip-flop is controlled by a clock input (CP) and an output enable input (OE). When the OE input is HIGH, the eight outputs are in a HIGH impedance state. An input protection circuit ensures that 0V to 7V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.

The buffered clock and buffered Output Enable are common to all flip-flops. The eight flip-flops will store the state of their individual D inputs that meet the setup and hold time requirements on the LOW-to-HIGH Clock (CP) transition. With the Output Enable (OE) LOW, the contents of the eight flip-flops are available at the outputs. When the OE is HIGH, the outputs go to the high impedance state. Operation of the OE input does not affect the state of the flip-flops.

CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC (opr.) = CPD • VCC • fIN + ICC / 8 (per F/F). The total CPD when n pcs. of the Octal D Flip-Flop operates can be calculated by the equation: CPD (total) = 20 + 12n.
