MC74VHC574DWR2
Octal D-Type Flip-Flop with 3-State Output
Octal D-T ype 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
