The MC54HC589J is an 8-bit shift register with a 3-state output manufactured by Freescale Semiconductor - NXP. This device features serial and parallel data input capabilities, along with a 3-state output, providing versatile data storage and retrieval options. It belongs to the HC (High-speed CMOS) family, offering improved speed and lower power consumption compared to older CMOS logic families.

Applications:

• Serial-to-parallel conversion
• Parallel-to-serial conversion
• Data latching
• Memory storage
• Microprocessor data interface

Features:

• High Speed: tPD = 14 ns (typ) at VCC = 5V
• Low Power Dissipation: ICC = 4 μA (max) at TA = 25°C
• High Noise Immunity: VNIH = VNIL = 28 % VCC
• Output Drive Capability: 10 LSTTL Loads
• Synchronous Serial and Parallel Loading
• 3-State Output
• Asynchronous Reset

Benefits:

• Flexible Data Handling: Supports both serial and parallel data input and output.
• Reduced Power Consumption: Low power dissipation is beneficial for battery-powered applications.
• Enhanced Noise Immunity: High noise immunity ensures reliable operation in noisy environments.
• Bus Compatibility: 3-state output allows for easy interfacing with bus-oriented systems.
• Easy Initialization: Asynchronous reset enables quick clearing of the register.

Additional Details:

The MC54HC589J operates over a wide temperature range, typically -55°C to +125°C, making it suitable for industrial and military applications. It is housed in a ceramic Dual In-Line Package (DIP) for robust mechanical and environmental protection. The 3-state output allows the device to be disconnected from the bus when not actively transmitting data, preventing bus contention.
