UNISONIC TECHNOLOGIES CO., LTD U74LVC157 CMOS IC QUADRUPLE 2-LINE TO 1-LINE DATA SELECTORS/MULTIPLEXERS DESCRIPTION The U74LVC157 is designed for 1.65V to 3.6V VCC operation. The device features a common strobe ( G ) input. 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. SOP-16 FEATURES * Operate From 1.65V to 3.6V * Inputs Accept Voltages to 5.5V * Max tpd of 5.0ns at 3.3V * Typical VOLP (Output Ground Bounce)<0.8V at VCC=3.3V, TA=25°C * Typical VOHV (Output VOH Undershoot)>2V at VCC=3.3V, TA=25°C ORDERING INFORMATION Ordering Number U74LVC157G-S16-R U74LVC157G-S16-R Package SOP-16 (1) Packing Type (1) R: Tape Reel (2) Package Type (2) S16: SOP-16 (3) Green Package (3) G: Halogen Free and Lead Free Packing Tape Reel MARKING www.unisonic.com.tw Copyright © 2016 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-990.C U74LVC157 CMOS IC PIN CONFIGURATION FUNCTION TABLE INPUTS A B A /B H X X X L L L X L L H X L H X L L H X H Note: H: HIGH voltage level; L: LOW voltage level; X: Don’t care.
