UNISONIC TECHNOLOGIES CO., LTD U74LVC17A CMOS IC HEX SCHMITT-TRIGGER BUFFER DESCRIPTION The UTC U74LVC17A is a high-performance, low-power, low-voltage, Si-gate CMOS device and provides six non-inverting buffers with Schmitt trigger action. It is capable for transforming slowly changing input signals into sharply defined, jitter-free output signals. FEATURES * Operate From 1.65V to 5.5V * 5 V Tolerant Input/Output For Interfacing With 5 V Logic *±32 mA Output Drive (VCC =4.5V) * CMOS Low-Power Consumption And High Noise Immunity * IOFF Supports Partial-Power-Down Mode Operation * Latch-Up Performance Exceeds 100 mA ORDERING INFORMATION Ordering Number U74LVC17AG-P14-R Package TSSOP-14 www.unisonic.com.tw Copyright © 2010 Unisonic Technologies Co., Ltd Packing Tape Reel 1 of 5 QW-R502-410.A U74LVC17A CMOS IC PIN CONFIGURATION FUNCTION TABLE (Each Gate) INPUT(A) OUTPUT(Y) L L H H Note: H=High level, L=Low Level LOGIC SYMBOL (Each Gate) UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R502-410.A U74LVC17A 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 -0.5~VCC+0.5 V VOUT Low State Input Clamp Current IIK -50 mA Output Clamp Current 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.
