UNISONIC TECHNOLOGIES CO., LTD U74LVC1G79 CMOS IC SINGLE POSITIVE-EDGE-TRIGGERED D-TYPE FLIP-FLOP DESCRIPTION The U74LVC1G79 is a single positive-edge-triggered D-type flip-flop. When data at the data input (D) meets the set-up time requirements, the data is transferred to the outputs (Q) on the positive-going edge of the clock pulse. Following the hold-time interval, data at the D input can be changed without affecting the level at the outputs. This device has power-down protective circuit, preventing device destruction when it is powered down. FEATURES * Operate from 1.65V to 5.5V * Inputs accept voltages to 5.5V * Ioff supports partial-power-down mode * Low power dissipation: ICC=10μA (Max.) * ±24mA output drive(VCC=3.3V) ORDERING INFORMATION Ordering Number Lead Free Plating Halogen Free U74LVC1G79L-AL5-R U74LVC1G79G-AL5-R Package Packing SOT-353 Tape Reel MARKING www.unisonic.com.tw Copyright © 2012 Unisonic Technologies Co., Ltd 1 of 7 QW-R502-803.A U74LVC1G79 CMOS IC PIN CONFIGURATION FUNCTION TABLE (EACH GATE） INPUT OUTPUT CLK D Q ↑ ↑ H H L L L X Q0 Note: H: HIGH voltage level; L: LOW voltage level; X: Don’t care; ↑: Low to High CLK transition Q0: indicates the state of referenced input, one set-up time prior to the LOW-to-HIGH CLK transition LOGIC DIAGRAM (positive logic) UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 7 QW-R502-803.A U74LVC1G79 CMOS IC ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL VCC VIN Supply Voltage Input Voltage RATINGS -0.5 ~ +6.5 -0.5 ~ +6.5 -0.5 ~ VCC+0.5 UNIT V V V Output in the high or low state VOUT Output in the high-impedance or -0.5 ~ +6.5 V power-off state VCC or GND Current ICC ±100 mA Continuous Output Current (VOUT=0 ~ VCC) IOUT ±50 mA Input Clamp Current (VIN<0) IIK -50 mA Output Clamp Current (VOUT<0 ) IOK -50 mA Storage Temperature Range TSTG -65 ~ +150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
