UNISONIC TECHNOLOGIES CO., LTD U74LVC2G126 CMOS IC DUAL BUS BUFFER GATE WITH 3-STATE OUTPUTS DESCRIPTION MSOP-8 The U74LVC2G126 consists of two bus buffers with 3-state output controlled by enable input (nOE), when nOE is low, the output is disabling. Inputs can be driven from either 3.3V or 5V devices, so the device can be used in a mix 3.3V/5V system. This device is full specified for partial power-down protective circuit, preventing the backflow current through the device when it is powered down. TSSOP-8 FEATURES * Operation voltage range: 1.65~5.5V * Support 5V VCC operation * Low power dissipation * Input accept voltage to 5.5V ORDERING INFORMATION Ordering Number U74LVC2G126G-P08-R U74LVC2G126G-SM1-R Package TSSOP-8 MSOP-8 Packing Tape Reel Tape Reel MARKING MSOP-8 www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd TSSOP-8 1 of 6 QW-R502-231.E U74LVC2G126 PIN CONFIGURATION 1OE 1 8 VCC 1A 2 7 2OE 2Y 3 6 1Y GND 4 5 2A FUNCTION TABLE (each gate) INPUT(nOE) H H L CMOS IC INPUT(A) L H X OUTPUT(Y) L H Z LOGIC DIAGRAM (positive logic) UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R502-231.E U74LVC2G126 CMOS IC ABSOLUTE MAXIMUM RATING (unless otherwise specified) PARAMETER SYMBOL VCC VIN RATINGS -0.5~6.5 -0.5~6.5 Enable -0.5~VCC+0.5 Output Voltage Disable VOUT -0.5~6.5 Power-down -0.5~6.5 VCC or GND Current ICC ±100 Input Clamp Current(VIN<0) IIK -50 Output Clamp Current(VOUT<0) IOK ±50 Output Current IOUT ±50 Power Dissipation PD 300 Storage Temperature TSTG -65 ~ +150 Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
