The CD74AC139E from Texas Instruments is a dual 2-line to 4-line decoder/demultiplexer designed for 1.5-V to 5.5-V VCC operation. This component is suitable for high-performance memory-decoding or data-routing applications requiring very short propagation delay times.
Key electrical characteristics include a wide operating voltage range of 1.5V to 5.5V and balanced propagation delays. The device offers ±24mA output drive current, supporting a fanout to 15 F devices. It operates across a temperature range of -55°C to 125°C.
The CD74AC139E features fully buffered inputs, each representing only one normalized load to its driving circuit. It incorporates two enable inputs to simplify cascading and data reception. The active-low enable input can also be used as a data line in demultiplexing applications.
This IC is available in a 16-PDIP through-hole package. Its SCR-latchup-resistant CMOS process and circuit design exceed 2-kV ESD protection per MIL-STD-883, Method 3015.
