The CD74FCT16827ETMT is a high-speed dual non-inverting buffer from Harris Corporation, designed for demanding 5V systems. It provides two independent channels with 3-State outputs, capable of sinking up to 64mA and sourcing 32mA. This makes it ideal for driving high-capacitance buses, memory arrays, and control lines in servers, industrial equipment, and telecommunications. Its wide operating temperature range of -40°C to 85°C ensures reliable performance in harsh environments.
- High Drive Current (64mA Sink): Ensures reliable signal integrity on heavily loaded buses and long PCB traces.
- 3-State Outputs: Enables bus multiplexing and isolation, preventing data contention in shared-bus architectures.
- Wide Temperature Range (-40°C to 85°C): Suitable for industrial and automotive environments where temperature extremes are common.
- Dual-Channel Design: Saves board space by providing two buffers in a single 56-pin package.
High-Density Bus Line Driving
With 2 channels and 64mA sink capability, the CD74FCT16827ETMT can drive heavily loaded parallel buses in memory systems or backplanes, ensuring signal integrity over long traces.
Memory Address Buffering
In DRAM or SRAM controllers, this buffer isolates the memory array from the controller's address lines, reducing capacitive loading and preventing signal degradation.
3-State Bus Isolation
The 3-State outputs allow multiple devices to share a common data bus. By disabling the outputs, the buffer can be effectively removed from the bus, preventing contention.
Server and Networking Equipment
In networking switches and servers, this buffer is used to fan out control signals to multiple peripheral slots, maintaining clean logic levels across the system.
Industrial Control I/O
For PLCs and industrial controllers, the buffer provides robust signal conditioning for interfacing with external sensors and actuators over 5V logic rails.
Test and Measurement Equipment
In ATE (Automated Test Equipment), the high drive current and fast switching of the 74FCT family make it suitable for driving capacitive loads in pin electronics.
