| Part Number | 74HC139 |
| Manufacturer | nexperia |
| Title | Dual 2-to-4 line decoder/demultiplexer |
| Description | The 74HC139; 74HCT139 decodes two binary weighted address inputs (nA0, nA1) to four mutually exclusive outputs (nY0 to nY3). Each decoder features an enable input (nE). When nE is HIGH all outputs are forced HIGH. The enable input can be used as the data input for a 1-to-4 demultiplexer application.. |
| Features |
an enable input (nE). When nE is HIGH all outputs are forced HIGH. The enable input can be used as the data input for a 1-to-4 demultiplexer application. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
2. Features and benefits
• Input levels: • For 74HC139: CMOS level • For 74HCT139: TTL level • Demultiplexing capab. |

| Title | Dual 2-Line To 4-Line Decoders/Demultiplexers |
| Description | The SNx4HC139 contains two two-to-four decoders with one active low output strobe G. When the outputs of one channel are gated by the strobe input, they are all forced into the high state. When the outputs are not disabled by the strobe input, only the selected output is low while all others are hi. |
| Features |
• Targeted specifically for high-speed memory decoders and data-transmission systems • Wide operating voltage range of 2 V to 6 V • Outputs can drive up to 10 LSTTL loads • Low power consumption, 80-μA max ICC • Typical tpd = 10 ns • ±4-mA output drive at 5 V • Low input current of 1 μA max • Incorporate two enable inputs to simplify cascading and/or data reception xA0 xA1 2 Description The SNx4. |
