Instructions for SN74AHCT139NE4

1. Power Supply: Ensure the supply voltage (VCC) is within the range of 2.0 to 5.5 volts.
2. Decoding Functionality: The SN74AHCT139NE4 is a 1-of-4 decoder/demultiplexer. It has two binary address inputs (A0, A1) and four outputs (Y0 to Y3). The enable input (G) must be low for the device to operate.
3. Output States: When enabled, only one output is active LOW corresponding to the binary input on A0 and A1. All other outputs are HIGH.
4. Handling Static Electricity: Handle with care to avoid damage from static electricity; use proper anti-static precautions.
5. Operating Temperature: Ensure the ambient temperature (TA) does not exceed the operational limits specified in the datasheet.
6. Mounting and Storage: Follow recommended guidelines for mounting and storage conditions to prevent damage or degradation of performance.

For detailed specifications and further instructions, refer to the official Texas Instruments datasheet for the SN74AHCT139NE4.
