Description:

• Texas Instruments offers the SN74HC138N, a high-speed 3-to-8-line decoder/demultiplexer.
• It is intended to convert three binary inputs into eight discrete outputs, with each representing one of the binary input combinations.
• The SN74HC138N's rugged architecture and varied features make it an excellent choice for a variety of applications that require decoding and data routing.
• By decoding three binary inputs (A, B, and C) into one of eight outputs, the 3-to-8 Line Decoder/Demultiplexer generates a distinct low signal for every possible combination of inputs.
• Active Low Outputs: The outputs are inverted, which means that one output is driven low while the others remain high.
• Wide Voltage Range: Operates with a supply voltage range of 2V to 6V, making it suitable for a variety of logic levels.
• Low power consumption with a maximum quiescent current of 80µA, making it suitable for battery-powered electronics.
• High-Speed Operation: A typical propagation delay of 15ns at 5V ensures fast response times for high-speed applications.
• High Fan-Out Capability: Each output may drive up to ten LSTTL loads, allowing it to connect to many devices.
• Enable Inputs: Three enable inputs (two active-low, one active-high) provide flexible control over the output state.
