Description
The CD74AC153 and CD74ACT153 are dual 4-input multiplexers that utilize the Harris Advanced CMOS Logic technology. One of the four sources for each section is selected
by the common Select inputs, S0 and S1. When the Enable
inputs (
1E, 2E) are HIGH, the outputs are in the low state.

CAUTION: These devices are sensitive to electrostatic discharge. Users should follow proper IC Handling Procedures.
FAST™ is a Trademark of Fairchild Semiconductor.
CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
3. For up to 4 outputs per device, add ±25mA for each additional output.
4. Unless otherwise specified, all voltages are referenced to ground.
5. θJA is measured with the component mounted on an evaluation PC board in free air.
