TC74VHCT574AF Overview
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHCT574AF, TC74VHCT574AFK Octal D-Type Flip-Flop with 3-State Output The TC74VHCT574A is an advanced high speed CMOS OCTAL FLIPFLOP 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 ). When the OE input is high, the eight outputs are in a high impedance state. The input voltage are patible with TTL output voltage. This device may be used as a level converter for interfacing 3.3 V to 5 V system. Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device destruction due...
