TECHNICAL DATA
Dual 2-to-4 line decoder/demultiplexer; inverting
The KK74LV139 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HCT139. The74LV139 is dual 2-to-4 line decoder/demultiplexer . This device has two independent decoders, each accepting two binary weighted inputs (A0a,A0b and A1a,A1b) and providing four mutually exclusive active LOW outputs (nY0 to nY3). Each decoder has an active LOW enable input (nE) When nE is HIGH, every output is forced HIGH. The enable can be used as the data input for a 1-to-4 demultiplexer application.
• • • • • Optimized for Low Voltage applications:1.2 to 3.6 V Demultiplexing capability Two independent 2-to-4 decoders Multifunction capability Active LOW mutually exclusive outputs
