HIGH-SPEED CMOS
DUAL 4-INPUT
MULTIPLEXER
DESCRIPTION:
The IDTQS74FCT153T is a high-speed CMOS TTL-compatible dual
4-input multiplexer. 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.
