OCTAL EDGE-TRIGGERED

D-TYPE FLIP-FLOPS WITH

3-STATE OUTPUTS

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=15pF

* Max ICC of 4uA

* Typical VOL< 0.36V at VCC=4.5V, IO=8mA, TA=25°C

* Typical VOH> 3.94V at VCC=4.5V, IO =-8mA, TA=25°C
