TOSHIBA 74VHCT574AFT

The 74VHCT574AFT is an advanced high speed CMOS OCTAL FLIP-FLOP with 3-STATE OUTPUT fabricated with silicon gate C2MOS 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 (CK) and an output enable input OE(overline). When the OE(overline) input is high, the eight outputs are in a high impedance state. The input voltage is compatible with TTL output voltage. This device may be used as a level converter for interfacing 3.3 V to 5 V Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc.
