UNISONIC TECHNOLOGIES CO., LTD U74LVC126A CMOS IC QUADRUPLE BUS BUFFER GATES WITH 3-STATE OUTPUTS DESCRIPTION The U74LVC126A are quadruple bus buffer gates featuring independent line drivers with 3-state outputs. When OE is low, the nY outputs are in a high-impedance state. When OE is high, the device passes non-inverted data from the nA input to its nY output. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pull-down resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. Inputs can be driven from either 3.3V to 5V devices. This feature allows the use of these devices as translators in a mixed 3.3V/5V system environment. FEATURES * 1.65V to 3.6V VCC Operation * Max tPD of 4.7ns from A to Y at VCC = 3.3V, CL = 50pF, RL = 500Ω * ±24mA output driver at 3V ORDERING INFORMATION Ordering Number U74LVC126AG-S14-R U74LVC126AG-P14-R Package SOP-14 TSSOP-14 Packing Tape Reel Tape Reel MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-705.B U74LVC126A CMOS IC PIN CONFIGURATION FUNCTION TABLE INPUT OE H H L OUTPUT Y H L Z A H L X LOGIC DIAGRAM (positive logic) 1OE 1A 2OE 2A 1 2 3OE 3 1Y 4 5 4OE 6 2Y UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3A 4A 10 9 8 3Y 13 12 11 4Y 2 of 6 QW-R502-705.B U74LVC126A CMOS IC ABSOLUTE MAXIMUM RATING (unless otherwise specified) PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC -0.5~6.5 V Input Voltage VIN -0.5~6.5 V Output Voltage VOUT -0.5~VCC +0.5 V Input Clamp Current (VIN<0) IIK -50 mA Output Clamp Current (VOUT<0, or VOUT>VCC) IOK -50 mA Output Current IOUT ±50 mA VCC or GND Current ICC ±100 mA PD mW Power Dissipation 500 Storage Temperature TSTG -65 ~ +150 °C Note: 1.
