UNISONIC TECHNOLOGIES CO., LTD U74HC2G125 CMOS IC DUAL BUFFER/LINE DRIVER; 3-STATE DESCRIPTION The U74HC2G125 is a high speed, Si-gate CMOS device. The U74HC2G125 provides two non-inverting buffer/line drivers with 3-state output. The 3-state output is controlled by the output enable input (pin nOE ). A HIGH level at pin nOE causes the output to assume a high-impedance OFF-state. TSSOP-8 FEATURES * Wide supply voltage range from 2.0V to 6.0V * Symmetrical output impedance * High noise immunity * Low power consumption * Balanced propagation delays * Multiple package options * Specified from -40 °C to +125 °C ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HC2G125L-P08-T U74HC2G125G-P08-T U74HC2G125L-P08-R U74HC2G125G-P08-R www.unisonic.com.tw Copyright © 2014 Unisonic Technologies Co., Ltd Package Packing TSSOP-8 TSSOP-8 Tube Tape Reel 1 of 6 QW-R502-A58.A U74HC2G125 CMOS IC PIN CONFIGURATION PIN CONFIGURATION PIN No SYMBOL 1, 7 1OE , 2OE 2. 5 4 6, 3 8 1A, 2A GND 1Y, 2Y VCC FUNCTIONAL DIAGRAM FUNCTION TABLE DESCRIPTION Output enable input (active LOW) Data input Ground (0V) Data output Supply voltage Control Input Output nOE nA nY L L L L H H H X Z H=HIGH voltage level; L=LOW voltage level; X=don’t care; Z=high-impedance OFF-state UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R502-A58.A U74HC2G125 CMOS IC ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNIT Supply Voltage VCC -0.5 +7.0 V Input Voltage VI -0.5 +7.0 V Input Clamping Current IIK VI<-0.5V or VI>VCC+0.5V ±20 mA Output Clamping Current IOK VO<-0.5V or VO>VCC+0.5V ±20 mA Output Current IO VO=-0.5V ~ (VCC+0.5V) 35 mA Supply Current ICC 70 mA Ground Current IGND -70 mA Power Dissipation PD 300 mW Storage Temperature TSTG -65 +150 °C Note: The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
