The CD74LPT16827AMT from Harris Corporation is a dual-channel, non-inverting buffer in the 74LPT logic family. It operates from 2.7V to 3.6V, featuring 3-State outputs with 24mA drive capability. Packaged in a 56-TFSOP, it is designed for signal buffering and isolation in 3.3V digital systems. Common applications include FPGA interfacing, clock distribution, and industrial control I/O.
- Balanced 24mA Drive: Provides sufficient current for standard logic loads while minimizing power consumption.
- 3-State Outputs: Enables bus sharing and reduces power when outputs are disabled.
- Wide Temperature Range (-40°C to 85°C): Suitable for industrial and automotive environments.
- Compact 56-TFSOP Package: Saves board space in dense designs.
Signal Buffering in FPGA Interfaces
The CD74LPT16827AMT buffers weak FPGA output signals, providing the necessary drive strength (24mA) to interface with peripheral devices over longer PCB traces.
Clock Distribution Networks
In clock distribution, this buffer isolates the clock source from multiple loads, preventing fan-out issues and maintaining signal rise/fall times in 3.3V systems.
Memory Module Address Buffering
For DIMM modules, the dual-channel buffer amplifies address signals, ensuring reliable setup/hold times across multiple memory banks.
Industrial Sensor Interfacing
In industrial controls, it buffers sensor outputs to PLC inputs, providing 3-State isolation when sensors are not actively driving the line.
Test Equipment I/O Isolation
In automated test equipment, the buffer isolates the measurement unit from the device under test, preventing loading effects and improving measurement accuracy.
Automotive Body Control Modules
For automotive ECUs, this buffer drives indicator LEDs and control signals, with 3-State outputs allowing safe shutdown in fault conditions.
