OCTAL TRANSPARENT D-TYPE LATCHES WITH 3-STATE OUTPUTS
DESCRIPTION
The U74AHCT374 is a octal edge-triggered D-type flip-flops
with 3-state outputs and 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.
