74F50728 is a synchronizing cascaded dual positive edge-triggered D-type flip-flop
The Philips 74F50728 is an integrated circuit designed to synchronize incoming signals to a system clock. It features two pairs of cascaded D-type flip-flops that are pin-compatible with the 74F74, allowing for plug-in retrofitting in existing systems.
A key feature of this device is its metastable immune characteristics, ensuring outputs never display a metastable state even if setup and hold times are violated. This significantly reduces the probability of system crashes caused by glitches or oscillations during signal synchronization.
| Maximum clock frequency (fmax) | 145 MHz |
|---|---|
| Output skew | less than 1.5 ns |
| Industrial temperature range | -40°C to +85°C |
| Supply voltage (Vcc) | 4.5 V to 5.5 V |
The device is designed to synchronize incoming signals to a system clock by capturing and releasing data over two clock cycles.
The outputs can never display a metastable state due to setup and hold time violations, preventing glitches or oscillations.
