UNISONIC TECHNOLOGIES CO., LTD U74LVC2G17 CMOS IC DUAL SCHMITT-TRIGGER BUFFER DESCRIPTION The UTC U74LVC2G17 is a high-performance, low-power, low-voltage, Si-gate CMOS device which provides two independent buffers with Schmitt trigger action. It is capable of transforming slowly changed input signals into sharply defined, jitter-free output signals. 5 6 1 3 SOT-363 ORDERING INFORMATION Ordering Number U74LVC2G17G-AL6-R 2 FEATURES * Operate From 1.65V to 5.5V * 5 V tolerant input/output for interfacing with 5 V logic *±24mA output drive (VCC = 3.3V) * CMOS low-power consumption and high noise immunity * IOFF Supports Partial-Power-Down Mode Operation * Latch-up performance exceeds 100mA * Specified from -40 °C to +85 °C * Halogen Free 4 Package SOT-363 Packing Tape Reel MARKING www.unisonic.com.tw Copyright © 2009 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-356.A U74LVC2G17 PIN CONFIGURATION FUNCTION TABLE INPUT(A) L H H=High level L=Low Level CMOS IC OUTPUT(Y) L H LOGIC SYMBOL UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R502-356.A U74LVC2G17 CMOS IC ABSOLUTE MAXIMUM RATING PARAMETER Supply Voltage Input Voltage (Note 2) Output Voltage (Note 2,3) High-Impedance Power-Off State High State SYMBOL VCC RATINGS -0.5~6.5 UNIT V VIN -0.5~6.5 V -0.5~6.5 V VOUT -0.5~VCC+0.5 V Low State Input Clamp Current (VIN<0) IIK -50 mA Output Clamp Current (VOUT<0) IOK -50 mA Output Current IOUT ±50 mA VCC or GND Current ICC ±100 mA Junction Temperature TJ 150 °C Storage Temperature TSTG -65 ~ +150 °C Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed. 3. The value of VCC is provided in the recommended operating conditions table.
