UNISONIC TECHNOLOGIES CO., LTD U74AHCT1G14 CMOS IC SINGLE SCHMITT-TRIGGER INVERTER DESCRIPTION The U74AHCT1G14 is a single schmitt-trigger inverter providing the function Y = A . The gates of 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 * Operation voltage range: 4.5V ~5.5V * Low Power Current: ICC=1μA (Max.) * ±8mA Output Drive at 5V * Inputs are TTL-Voltage Compatible ORDERING INFORMATION Ordering Number U74AHCT1G14G-AF5-R U74AHCT1G14G-AL5-R Package SOT-25 SOT-353 Packing Tape Reel Tape Reel MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 4 QW-R502-518.D U74AHCT1G14 CMOS IC PIN CONFIGURATION FUNCTION TABLE (each gate) INPUT(A) L H OUTPUT(Y) H L LOGIC DIAGRAM (positive logic) Logic symbol UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw IEC logic symbol 2 of 4 QW-R502-518.D U74AHCT1G14 CMOS IC ABSOLUTE MAXIMUM RATING (TA=25°С, unless otherwise specified) PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC -0.5 ~ 7 V Input Voltage VIN -0.5 ~ 7 V Output Voltage VOUT -0.5 ~ VCC +0.5 V VCC or GND Current ICC ±50 mA Output Current IOUT ±25 mA Input Clamp Current IIK -20 mA Output Clamp Current IOK ±20 mA Operating Temperature TOPR -40 ~ + 125 °С Storage Temperature TSTG -65 ~ + 150 °С Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
