The IDTQS74FCT2823T is a 9-bit high-speed CMOS TTL-compatible buffered register with 3-state outputs, with a 25 resister that is useful for driving transmission lines and reducing system noise. The 2823 series parts can replace the 823 series to reduce noise in an existing design. All inputs have clamp diodes for undershoot noise suppression. All outputs have ground bounce suppression. Outputs will not load an active bus when Vcc is removed from the device.

NOTE: 1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
