Octal D-Type Flip-Flop
with 3-State Output
The MC74VHC574 is an advanced high speed CMOS octal flip–flip with
3–state 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 8–bit D–type flip–flop 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 internal circuit is composed of three stages, including a buffer output
which provides high noise immunity and stable output. The inputs tolerate
voltages up to 7V, allowing the interface of 5V systems to 3V systems.
• High Speed: fmax = 180MHz (Typ) at VCC = 5V
• Low Power Dissipation: ICC = 4µA (Max) at TA = 25°C
• High Noise Immunity: VNIH = VNIL = 28% VCC
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Designed for 2V to 5.5V Operating Range
• Low Noise: VOLP = 1.2V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300mA
• ESD Performance: HBM > 2000V; Machine Model > 200V
• Chip Complexity: 266 FETs or 66.5 Equivalent Gates
