The 54ACTQ827FMQB is a single non-inverting buffer from National Semiconductor's 54ACTQ family. It combines high-speed CMOS technology with TTL-compatible inputs, operating at a nominal 5V supply. The 3-State output allows for bus-oriented applications, and it can source or sink 24mA. Packaged in a 24-pin ceramic flatpack, it is designed for high-reliability and military/aerospace applications.
- TTL-Compatible Inputs: Directly interfaces with legacy 5V TTL logic without external translation.
- Balanced 24mA Drive: Provides consistent source and sink current for driving moderate loads.
- Military Temperature Range: Operates reliably from -55°C to 125°C.
- Flatpack Package: Low-profile, space-saving ceramic package for high-density boards.
High-Reliability Bus Interface
In aerospace or defense systems, this buffer provides a reliable interface between a 5V controller and a data bus, with 3-State control for multiplexing.
Signal Buffering in Harsh Environments
The -55°C to 125°C operating range makes it suitable for avionics and down-hole drilling equipment.
Level Shifting (5V to 5V TTL)
It can buffer 5V TTL signals while providing CMOS-level output drive, ensuring compatibility with mixed-logic systems.
Memory Address/Data Buffering
Use it to buffer address or data lines in high-speed memory systems, reducing signal degradation.
Test and Measurement Instrumentation
Provides a clean, buffered output for driving long coaxial cables in automated test equipment.
