HD74LV139A

HD74LV139A Dual 2-to-4 line Decoder / Demultiplexers ADE-205-262 (Z) 1st Edition March 1999 Description The HD74LV139A is designed to be used in high-performance memory-decoding or data-routing applications requiring very short propagation delay times. The active-low enable input can be used as a data line in demultiplexing applications. This decoder/demultiplexer features fully buffered inputs, each of which represents only one normalized load to its driving circuit. Low-voltage and high-speed operation is suitable for the battery-powered products (e.g., notebook computers), and the low-power consumption extends the battery life. Features VCC = 2.0 V to 5.5 V operation All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VO (Max.) = 5.5 V (@VCC = 0 V) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C) Output current ±6 mA (@VCC = 3.0 V to 3.6 V), ±12 mA (@VCC = 4.5 V to 5.5 V) Function Table Inputs Select G1 H L L L L B X L L H H A X L H L H Outputs Y0 H L H H H Y1 H H L H H Y2 H H H L H Y3 H H H H L Note: H: High level L: Low level X: Immaterial HD74LV139A Pin Arrangement 1G 1A 1B 1 2 3 16 VCC 15 2G 14 2A 13 2B 12 2Y0 11 2Y1 10 2Y2 9 2Y3 1Y0 4 1Y1 5 1Y2 6 1Y3 7 GND 8 (Top view) Absolute Maximum Ratings Item Supply voltage range Input voltage range* 1 1, 2 Symbol VCC VI VO Ratings –0.5 to 7.0 –0.5 to 7.0 –0.5 to VCC + 0.5 –0.5 to 7.0 Unit V V V Conditions Output voltage r...
