UNISONIC TECHNOLOGIES CO., LTD U74HC157 CMOS IC QUADRUPLE 2-LINE TO 1-LINE DATA SELECTORS / MULTIPLEXERS SOP-16 DESCRIPTION The U74HC157 is a quadruple 2-line to 1-line data selectors/multiplexers. When G is high all outputs are low. When G is low a 4-bit word is selected from one of two sources and is routed to the four outputs. The device provides true data. FEATURES TSSOP-16 * Wide supply voltage range from 2V to 6V * Typical tPD at 11ns from A or B to Y at 6V, CL=50pF * Low power consumption, ICC = 8 μA (MAX) at 6V * ±6 mA output driver at 5V * Low Input Current of 0.1uA Max ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HC157L-S16-R U74HC157G-S16-R U74HC157L-S16-T U74HC157G-S16-T U74HC157L-P16-R U74HC157G-P16-R U74HC157L-P16-T U74HC157G-P16-T www.unisonic.com.tw Copyright © 2012 Unisonic Technologies Co., Ltd Package Packing SOP-16 SOP-16 TSSOP-16 TSSOP-16 Tape Reel Tube Tape Reel Tube 1 of 6 QW-R502-812.A U74HC157 CMOS IC PIN CONFIGURATION FUNCTION TABLE INPUTS G H L L L L A/B X L L H H OUTPUTS A B Y X L H X X X X X L H L L H L H LOGIC DIAGRAM UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R502-812.A U74HC157 CMOS IC ABSOLUTE MAXIMUM RATING (TA =25°C , unless otherwise specified) PARAMETER SYMBOL RATINGS UNIT Supply Voltage Range VCC -0.5~7 V Input Clamp Current (VIN<0) IIK ±20 mA Output Clamp Current (VOUT<0, or VOUT>VCC) IOK ±20 mA Output Current IOUT ±35 mA VCC or GND Current ICC ±70 mA Storage Temperature TSTG -65 ~ +150 °C Note: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied.
