IDTQS74FCT2646AT/CT
DESCRIPTION:
The IDTQS74FCT2646T is an 8-bit high-speed CMOS TTL-compatible
registered bus transceiver with 3-state outputs. These outputs also have
25Ω resistors, useful for driving transmission lines and reducing system
noise. The 2646 series parts can replace the 646 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.
