74VHCT374A Octal D-Type Flip-Flop with 3-STATE Outputs May 2007 74VHCT374A Octal D-Type Flip-Flop with 3-STATE Outputs Features ■ High speed: fMAX = 140MHz (Typ.) at TA = 25°C ■ High noise immunity: VIH = 2.0V, VIL = 0.8V ■ Power down protection is provided on all inputs and tm General Description The VHCT374A 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. Protection circuits ensure that 0V to 7V can be applied to the input and output(1) pins without regard to the supply voltage. This device can be used to interface 3V to 5V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. Note: 1. Outputs in OFF-State. outputs ■ Low power dissipation: ICC = 4A (Max.) @ TA = 25°C ■ Pin and function compatible with 74HCT374 Ordering Information Order Number 74VHCT374AM 74VHCT374ASJ 74VHCT374AMTC Package Number M20B M20D MTC20 Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead Thin Shrink Small Outline Package (TSSOP), JE……
