UNISONIC TECHNOLOGIES CO., LTD U74LVC2G14 CMOS IC DUAL SCHMITT-TRIGGER INVERTER WITH 5V TOLERANT INPUT DESCRIPTION The UTC U74LVC2G14 is a high-performance, low-power, low-voltage, Si-gate CMOS device which provides two inverters with Schmitt trigger action. It is capable of transforming slowly changed input signals into sharply defined, jitter-free output signals. FEATURES * Operate From 1.65V to 5.5V * 5V tolerant input/output for interfacing with 5V logic *±24mA output drive (VCC =3.3V) * CMOS low-power consumption and high noise immunity * Halogen Free ORDERING INFORMATION Ordering Number U74LVC2G14G-AL6-R Package SOT-363 Packing Tape Reel MARKING www.unisonic.com.tw Copyright © 2009 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-355.A U74LVC2G14 CMOS IC PIN CONFIGURATION FUNCTION TABLE INPUT(A) L H H=High level L=Low Level OUTPUT(Y) H L LOGIC SYMBOL FUNCTIONAL DIAGRAM 1A 1Y 2A 2Y UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R502-355.A U74LVC2G14 CMOS IC ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL VCC VIN Supply Voltage Input Voltage high-impedance power-off High State Low State Output Voltage RATINGS -0.5 ~ +6.5 -0.5 ~ +6.5 UNIT V V -0.5 ~ 6.5 V -0.5 ~VCC+0.5 V VOUT VCC or GND Current ICC ±100 mA Continuous Output Current IO ±50 mA Input Clamp Current IIK -50 mA Output Clamp Current IOK -50 mA Storage Temperature TSTG -65 ~ + 150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
