U74AHCT14

UNISONIC TECHNOLOGIES CO., LTD U74AHCT14 HEX SCHMITT-TRIGGER INVERTER „ DESCRIPTION The U74AHCT14 is a high speed Si-gate CMOS device which contains six independent Schmitt-trigger inverters and they perform the function Y=A. The device have different input threshold levels for positive-going (VT+) and negative-going(VT-) signals because of the Schmitt-trigger action in the input. „ FEATURES * All inputs have Schmitt-trigger action * Inputs are TTL-Voltage compatible * Balanced propagation delays „ ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74AHCT14L-S14-R U74AHCT14G-S14-R U74AHCT14L-P14-R U74AHCT14G-P14-R Package SOP-14 TSSOP-14 CMOS IC Packing Tape Reel Tape Reel www.unisonic.com.tw Copyright © 2012 Unisonic Technologies Co., Ltd 1 of 4 QW-R502-799.A U74AHCT14 „ PIN CONFIGURATION CMOS IC „ FUNCTION TABLE (each gate) INPUT A L H „ LOGIC DIAGRAM (positive logic) OUTPUT Y H L IEC logic symbol UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 4 QW-R502-799.A U74AHCT14 CMOS IC „ ABSOLUTE MAXIMUM RATING (TA=25°C, unless otherwise specified)(Note 1) PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC -0.5~7 V Input Voltage VIN -0.5~7 V Output Voltage(active mode) VOUT -0.5~VCC+0.5 V Input Clamp Current(VIN<0) IIK -20 mA Output Clamp Current(VOUT<0) IOK ±20 mA Output Current VCC or GND Current IOUT ±25 mA ICC ±50 mA Storage Temperature TSTG -65 ~ +150 °C Note 1.
