MC74LCX139DTR2 Description

Short technical summary and product information.

The MC74LCX139DTR2 from On Semiconductor is a high-performance, dual 2-to-4 decoder/demultiplexer. It operates within a voltage range of 2.3V to 3.6V, making it suitable for low-voltage systems. The device features 5V tolerant inputs, allowing for seamless interface capability with 5V TTL logic.

 

This decoder/demultiplexer accepts two binary weighted inputs and provides four mutually exclusive active-LOW outputs. It includes an active-low Enable input, and all outputs remain HIGH unless the Enable is LOW. The MC74LCX139 can also function as an 8-output demultiplexer by utilizing one Enable input as the data input and the other as a strobe. Unused Enable inputs must be tied to ground.

 

With a current drive capability of 24mA at the outputs, it offers balanced sink and source performance. The device operates over a temperature range of -40°C to 85°C and is available in a 16-TSSOP surface mount package. Its high-speed operation and low static supply current contribute to reduced system power requirements. Latchup performance exceeds 500mA, and ESD protection is robust, with Human Body Model exceeding 2000V and Machine Model exceeding 200V.
