Introduction
SN74AHCT139DR Dual 2-to-4 Decoder/Demultiplexer
The SN74AHCT139DR is a dual 2-to-4 decoder/demultiplexer manufactured by TI, belonging to the AHCT logic family with TTL-compatible inputs and CMOS outputs.
Key Features
- Contains two independent 2-line-to-4-line decoders in a single package
- Each decoder accepts 2 address inputs (A, B) and 1 active-low enable input (G)
- When enabled (G = LOW), exactly one of the four outputs is active LOW based on the address code
- When disabled (G = HIGH), all outputs are HIGH
- TTL-compatible input levels for direct interface with TTL or 5V CMOS logic
- Wide operating voltage range: 4.5V to 5.5V
- Balanced CMOS push-pull outputs with high drive capability
Applications
- Address decoding in microcontrollers, microprocessors, and digital systems
- Memory bank selection (RAM/ROM decoding)
- Data routing and demultiplexing
- I/O device selection in digital circuits
- Logic function expansion and chip enable control
- High-noise-immunity control decoding in industrial and embedded systems
