MC74VHCT574A Octal DType FlipFlop with 3State Output The MC74VHCT574A is an advanced high speed CMOS octal flipflop with 3state output fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. This 8bit Dtype flipflop is controlled by a clock input and an output enable input. When the output enable input is high, the eight outputs are in a high impedance state. The VHCT inputs are compatible with TTL levels. This device can be used as a level converter for interfacing 3.3 V to 5.0 V, because it has full 5.0 V CMOS level output swings. The VHCT574A input and output (when disabled) structures provide protection when voltages between 0 V and 5.5 V are applied, regardless of the supply voltage. These input and output structures help prevent device destruction caused by supply voltageinput/output voltage mismatch, battery backup, hot insertion, etc. Features http://onsemi.com MARKING DIAGRAMS 20 VHCT574A AWLYYWWG 1 1 SOIC20WB SUFFIX DW CASE 751D 20 VHCT 574A ALYWG G 1 High Speed: fmax = 140 MHz (Typ) at VCC = 5.0 V Low Power Dissipation: ICC = 4 mA (Max) at TA = 25°C TTLCompatible Inputs: VIL = 0.8 V; VIH = 2.0 V Power Down Protection Provided on Inputs and Outputs Balanced Propagation Delays Designed for 4.5 V to 5.5 V Operating Range Low Noise: VOLP = 1.6 V (Max) Pin and Function Compatible with Other Standard Logic Families Latchup Performance Exceeds ……
