The M74HC85B1 is a high-speed CMOS 4-bit magnitude comparator designed and manufactured by STMicroelectronics. This integrated circuit is engineered to compare the magnitude of two 4-bit binary, BCD, or other monotonic codes and provide outputs that indicate the three possible states of comparison: less than, equal to, or greater than.

Key Features

• Logic Type: 4-bit Magnitude Comparator
• High-Speed Performance: The device ensures fast response times, making it suitable for high-speed data processing systems.
• Supply Voltage Range: Operates on a wide range of supply voltages from 2V to 6V, providing flexibility for various applications and compatibility with TTL levels.
• Low Power Consumption: Characterized by low quiescent current, which minimizes power consumption and makes it ideal for battery-operated devices.
• High Noise Immunity: Possesses a significant level of immunity to electrical noise, which is a critical feature for reliable operation in industrial environments.
• Output Capability: Capable of driving 10 LSTTL loads, which allows for a good level of fan-out and compatibility with other logic families.
• Pin and Function Compatible with 74 Series: The M74HC85B1 is designed to be pin-to-pin compatible with the standard 74 series, making it easy to upgrade existing systems.
