U74AHCT157

UNISONIC TECHNOLOGIES CO., LTD U74AHCT157 QUADRUPLE 2-LINE TO 1-LINE DATA SELECTOR/ MULTIPLEXER „ DESCRIPTION The U74AHCT157 is a quadruple 2-line to 1-line data selector/multiplexer. 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 devices provide true data. „ FEATURES * TTL-Voltage Compatible * Max tPD of 4.1ns from A or B to Y at 5V, CL=15pF * Low Quiescent Current: ICC = 2 μA (MAX) at 5.5V * ±8 mA output driver at 5V CMOS IC „ ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74AHCT157L-P16-R U74AHCT157G-P16-R U74AHCT157L-P16-T U74AHCT157G-P16-T Package TSSOP-16 TSSOP-16 Packing Tape Reel Tube www.unisonic.com.tw Copyright © 2011 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-652.A U74AHCT157 „ PIN CONFIGURATION CMOS IC „ FUNCTION TABLE INPUTS G A/B A HXX LLL L LH LHX LHX „ LOGIC DIAGRAM B X X X L H OUTPUTS Y L L H L H UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R502-652.A U74AHCT157 CMOS IC „ ABSOLUTE MAXIMUM RATING (TA =25°C ,unless otherwise specified) PARAMETER SYMBOL RATINGS UNIT Supply Voltage Range VCC -0.5~7 V Input Voltage Range Output Voltage Range Input Clamp Current (VIN<0) VIN VOUT IIK -0.5~7 -0.5~VCC +0.5 -20 V V mA Output Clamp Current (VOUT<0, or VOUT>VCC) Output Current VCC or GND Current IOK IOUT ICC ±20 mA ±25 mA ±50 mA Storage Temperature TSTG -65 ~ +150 °C Note: 1.
