UNISONIC TECHNOLOGIES CO., LTD U74LVC2G157 CMOS IC SINGLE 2-LINE TO 1-LINE DATA SELECTOR OR MULTIPLEXER DESCRIPTION The U74LVC2G157 is a single 2-line to 1-line data selector or multiplexer which is featured a common strobe ( G ) input. When the strobe is high, the output Y is low and Y is high regardless of the levels of other inputs. When the strobe is low, a single bit is selected from one of two sources and is transferred to the output with the true and complementary data. This device has power-down protective circuit, preventing device destruction when it is powered down. SOP-8 FEATURES * Operate from 1.65V to 5.5V * Inputs accept voltages to 5.5V * Ioff supports partial-power-down mode * Low power dissipation: ICC=10μA(Max.) * ±24mA output drive(VCC=3.3V) * Max tpd at 6ns of 3.3V ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74LVC2G157L-S08-T U74LVC2G157G-S08-T U74LVC2G157L-S08-R U74LVC2G157G-S08-R www.unisonic.com.tw Copyright © 2012 Unisonic Technologies Co., Ltd Package Packing SOP-8 SOP-8 Tube Tape Reel 1 of 5 QW-R502-809.A U74LVC2G157 PIN CONFIGURATION FUNCTION TABLE (EACH GATE) CMOS IC INPUTS OUTPUT A B Y G A/B Y H X X X L H L L L X L H L L H X H L L H X L L H L H X H H L Note: H: HIGH voltage level; L: LOW voltage level; X: Don’t care LOGIC DIAGRAM (positive logic) G A/B A 7 6 1 5 B 2 UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 Y Y 2 of 5 QW-R502-809.A U74LVC2G157 CMOS IC ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL VCC VIN Supply Voltage Input Voltage RATINGS -0.5 ~ +6.5 -0.5 ~ +6.5 -0.5 ~ VCC+0.5 Output in the high or low state VOUT Output in the high-impedance or -0.5 ~ +6.5 power-off state VCC or GND Current ICC ±100 Continuous Output Current (VOUT=0 to VCC) IOUT ±50 Input Clamp Current (VIN<0) IIK -50 Output Clamp Current (VOUT<0 ) IOK -50 Storage Temperature Range TSTG -65 ~ +150 Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
