UNISONIC TECHNOLOGIES CO., LTD U74AHC2G125 CMOS IC DUAL BUFFER/LINE DRIVER; 3-STATE DESCRIPTION The U74AHC2G125 is a high speed, Si-gate CMOS device. The U74AHC2G125 provides a dual non-inverting buffer/line drivers with 3-state output. The 3-state output is controlled by the output enable input ( nOE ). A HIGH at nOE causes the output to assume a high-impedance OFF-state. TSSOP-8 FEATURES * Symmetrical output impedance * High noise immunity * Low power dissipation * Balanced propagation delays * Multiple package options * Specified from -40 °C to +125 °C ORDERING INFORMATION Ordering Number U74AHC2G125G-P08-R Package TSSOP-8 Packing Tape Reel MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-A57.B U74AHC2G125 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-A57.B U74AHC2G125 CMOS IC ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL TEST 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 -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) ±25 mA Supply Current ICC 75 mA Ground Current IGND -75 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.
