74LV139 Dual 2-to-4 line decoder/demultiplexer Rev. 04 13 December 2007 Product data sheet 1. General description The 74LV139 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC139 and 74HCT139. The 74LV139 is a dual 2-to-4 line decoder/demultiplexer. It has two independent decoders, each accepting two binary weighted inputs (nA0 and nA1) and providing four mutually exclusive outputs (nY0 to nY3) that are LOW when selected. Each decoder has an active LOW input (nE). When nE is HIGH, every output is forced HIGH. The enable input can be used as the data input for a 1-to-4 demultiplexer application. 2. Features Wide operating voltage: 1.0 V to 5.5 V Optimized for low voltage applications: 1.0 V to 3.6 V Accepts TTL input levels between V = 2.7 V and V = 3.6 V CC CC Typical output ground bounce < 0.8 V at V = 3.3 V and T = 25 C CC amb Typical HIGH-level output voltage (V ) undershoot: > 2 V at V = 3.3 V and OH CC T =25 C amb Demultiplexing capability Two independent 2-to-4 line decoders Multifunction capability Active LOW mutually exclusive outputs ESD protection: HBM JESD22-A114E exceeds 2000 V MM JESD22-A115-A exceeds 200 V Multiple package options Specied from - 40 Cto+85 C and from - 40 C to +125 C 3.
