The 54ABT244J-QMLV is a robust non-inverting buffer from National Semiconductor, part of the 54ABT logic family. It offers 2 channels with 3-State outputs, delivering 24mA source and 48mA sink current. Operating from 4.5V to 5.5V, it is designed for 5V systems requiring high drive strength. The 20-CDIP ceramic package ensures durability and thermal stability, making it suitable for military and industrial applications. Its wide operating temperature range (-55°C to 125°C) guarantees reliable performance in harsh environments.
- Ceramic CDIP Package: Provides superior thermal and mechanical reliability compared to plastic packages, ideal for harsh environments.
- High Sink Current (48mA): Drives heavy loads and long traces without signal degradation.
- 3-State Outputs: Facilitates bus sharing and multiplexing, reducing component count.
- Proven 54ABT Family: Offers a balance of speed and power consumption, suitable for high-performance systems.
Through-Hole Bus Buffering
The 20-CDIP package is ideal for through-hole mounting in legacy systems. Use it to buffer data buses in industrial controllers where board space is not a constraint.
High-Reliability Avionics
With its ceramic package and military temperature range, this buffer is perfect for avionics systems that require high reliability and resistance to thermal stress.
5V Logic Level Shifting
Use the 3-State outputs with external pull-ups to shift 5V logic signals to 3.3V, enabling communication between older and newer logic families.
Fan-Out Expansion
The 48mA sink current allows driving up to 10 standard TTL loads, making it excellent for fan-out expansion in complex digital systems.
Test and Measurement Equipment
In ATE (Automated Test Equipment), this buffer provides clean, isolated signals to device-under-test pins, ensuring accurate measurements.
Redundant System Design
In redundant control systems, the 3-State outputs allow multiple buffers to be connected to the same bus, enabling failover without bus contention.
