NE529
DESCRIPTION
The NE529 is a high-speed analog voltage comparator which, for
the first time, mates state-of-the-art Schottky diode technology with
the conventional linear process. This allows simultaneous
fabrication of high-speed TTL gates with a precision linear amplifier
on a single monolithic chip.
FEATURES
• 10 ns propagation delay
• Complementary output gates
• TTL or ECL compatible outputs
• Wide common-mode and differential voltage range
• Typical gain 5000
APPLICATIONS
• A/D conversion
• ECL-to-TTL interface
• TTL-to-ECL interface
• Memory sensing
• Optical data coupling
