U74AHC574 Datasheet | Unisonic Technologies

DESCRIPTION The U74AHC574 is a octal edge-triggered D-type flip-flops with 3-state outputs, and it has 8 channels. When the OE input is low, on the positive transition of the clock (CLK) input, the Q outputs are set to the logic levels of the data (D) inputs. When the OE input is high, the outputs are in the high-impedance. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. - FEATURES - Operate from 2V to 5.5V - Max tpd of 13.2 ns at at VCC=3.3V, CL=15p F - Max ICC of 4u A - Typical VOL< 0.36V at VCC=4.5V, IO=8m A, TA=25°C - Typical VOH> 3.94V at VCC=4.5V, IO =-8m A, TA=25°C - ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74AHC574L-P20-R U74AHC574G-P20-R U74AHC574L-P20-T U74AHC574G-P20-T Package TSSOP-20 TSSOP-20 CMOS IC TSSOP-20 Packing Tape Reel Tube .unisonic..tw Copyright © 2012 Unisonic Technologies Co., Ltd 1 of 7 QW-R502-796.A - PIN CONFIGURATION OE 1D 2D 3D 4D 5D 6D 7D 8D GND 1 2 3 4 5 6 7 8 9 10 - FUNCTION TABLE INPUTS(OE) L L L H - LOGIC SYMBOL INPUTS(CLK) ↑ ↑ H or L X 20 VCC 19 1Q 18 2Q 17 3Q 16 4Q 15 5Q 14 6Q 13 7Q 12 8Q 11 CLK INPUTS(D) H L X...
