KK74LV139

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 KK74LV139 N SUFFIX PL AST IC 16 1 16 1 D SUFFIX S O IC ORDERING INFORMATION KK74LV139N Plastic KK74LV139D SOIC TA = -40° to 125° C for all packages • Output capability: standard PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs E A1 X L L H H Outputs A0 X L H L H Y0 Y1 Y2 Y3 H L H H H H H L H H H H H L H H H H H L PIN 16 =VCC PIN 8 = GND H L L L L H = high level (steady state) L = low level (steady state) X = don’t care 1 KK74LV139 MAXIMUM RATINGS Symbol VCC IIK IOK IO ICC Tstg PD * Parameter Value -0.5 to +7.0 ±20 ±50 ±25 ±50 -65 to +150 750 500 260 °C VI< - 0.5 or VI> Vcc+0.5V VO< - 0.5 or VO> Vcc+0.5V -0.5В
