The SNJ54ACT16244WD is a high-speed, non-inverting buffer from Texas Instruments' 54ACT logic family. It provides four channels of signal buffering with 3-State outputs, capable of sourcing or sinking 24mA. Operating over a 4.5V to 5.5V supply range, it is designed for 5V systems requiring robust drive and high noise immunity. Its wide temperature range (-55°C to 125°C) and 48-CFlatPack package make it suitable for demanding aerospace, defense, and industrial applications where reliable signal distribution is critical.
- High Drive Current (24mA): Ensures reliable signal transmission to heavily loaded buses and long traces.
- Wide Temperature Range (-55°C to 125°C): Guarantees operation in extreme environments, ideal for military and aerospace.
- 3-State Outputs: Enables bus multiplexing and prevents bus contention in multi-master systems.
- 54ACT Family: Combines high-speed CMOS performance with TTL-compatible inputs for easy interfacing.
High-Reliability Bus Interfacing
In aerospace and defense systems, the SNJ54ACT16244WD's 3-State outputs and 24mA drive enable reliable communication on shared data buses, even in harsh environments with wide temperature swings (-55°C to 125°C).
Signal Buffering for Memory Arrays
Use this buffer to regenerate address or control signals in large memory systems. The 4 channels and high drive current prevent signal degradation when fan-out exceeds standard logic limits.
Level Shifting in Mixed-Voltage Systems
While optimized for 5V, its TTL-compatible inputs allow interfacing with 3.3V logic. The 3-State outputs facilitate safe connection to 5V buses without contention.
Driving High-Capacitance Loads
In industrial control panels, the 24mA output current can drive long cable runs and high-capacitance loads, maintaining signal integrity over distance.
Redundant System Architecture
The 3-State outputs allow multiple buffers to be connected to the same bus, enabling redundant paths in critical systems. A failed buffer can be tri-stated without affecting system operation.
Military and Space Electronics
With its extended temperature range and robust 54ACT family design, this buffer is ideal for satellite telemetry, flight control, and other mission-critical electronics where reliability is paramount.
