description/ordering information
The CD74HCT574 is an octal D-type flip-flop with
3-state outputs and the capability to drive 15 LSTTL
loads. The eight edge-triggered flip-flops enter data
into their registers on the low-to-high transition of the
clock (CP). The output enable (OE) controls the
3-state outputs and is independent of the register
operation. When OE is high, the outputs are in the
high-impedance state.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltages referenced to GND unless otherwise specified.
2. The package thermal impedance is calculated in accordance with JESD 51-7.
