CD54ACT244F3A

The CD54ACT244F3A is an octal non-inverting buffer and line driver with 3-state outputs, manufactured by Texas Instruments as part of the Advanced CMOS logic family. It integrates eight independent channels with TTL-compatible inputs that tolerate input levels down to 2 V while operating from a nominal 5 V supply, delivering balanced high-current drive for heavily loaded buses and memory-address fanout. The ACT process provides fast switching with typical propagation delays below 10 ns, and the device maintains performance across the full military temperature range of –55 °C to +125 °C. Housed in a hermetic ceramic dual-in-line package (CDIP), the part offers robust protection against humidity, shock, and contamination in severe environments.

Typical applications include avionics flight-control buses, radar signal distribution, missile guidance interfaces, and secure communications payloads where deterministic level translation, signal integrity, and prolonged operation without recalibration are mandatory. The 3-state outputs enable straightforward implementation of bidirectional data paths and multiplexed architectures in centralized processing units and I/O expansion modules. The F3A suffix reflects processing and screening compliant with MIL-STD-883, making the device suitable for defense, aerospace, and high-reliability industrial programs that demand approved vendor sources, full lot traceability, and extended product-lifecycle commitments. Procurement teams typically evaluate such military-grade logic for long-term availability, documentation packages, and conformity to stringent quality standards—factors that reduce the risk of redesign due to obsolescence in sustained-deployment systems.
