U74AHC374

UNISONIC TECHNOLOGIES CO., LTD U74AHC374 OCTAL EDGE-TRIGGERED D-TYPE FLIP-FLOPS WITH 3-STATE OUTPUTS CMOS IC  DESCRIPTION The U74AHC374 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 12.7ns at VCC=3.3V, CL=15pF * Max ICC of 4uA * Typ VOL< 0.36V at VCC=4.5V,IO=8mA,TA=25°C * Typ VOH> 3.94V at VCC=4.5V,IO=-8mA, TA=25°C  ORDERING INFORMATION Ordering Number U74AHC374G-P20-R Package TSSOP-20 TSSOP-20 Packing Tape Reel ■ MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-668.B U74AHC374  PIN CONFIGURATION CMOS IC  FUNCTION TABLE INPUTS( OE ) L L L H INPUTS(CLK) ↑ ↑ H or L X  LOGIC SYMBOL OE 1 CLK 11 1D 3 2D 4 3D 7 4D 8 5D 13 6D 14 7D 17 8D 18  LOGIC DIAGRAM INPUTS(D) H L X X EN C1 1D OUTPUT(Q) H L Q0 Z 2 1Q 5 2Q 6 3Q 9 4Q 12 5Q 15 6Q 16 7Q 19 8Q UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R502-668.B U74AHC374 CMOS IC  ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL RATINGS UNIT Supply Volta...
