All PI74FCT2XXX devices have a built-in 25-ohm series resistor on all outputs to reduce noise resulting from reflections, thus eliminating the need for an external terminating resistor. The PI74FCT153T/253T and PI74FCT2153T/2253T are highspeed dual 4-input multiplexers. The PI74FCT153T/2153T has TTL outputs, while the PI74FCT253T/2253T has 3-state outputs. The output buffers are designed with a power-off disable allowing “live insertion” of boards when used as backplane drivers.
