IDT54FCT257T multiplexer equivalent, fast cmos quad 2-input multiplexer.
* Common features:
– Low input and output leakage ≤1µA (max.)
– CMOS power levels
– True TTL input and output compati.
The FCT157T, FCT257T/FCT2257T are high-speed quad 2-input multiplexers built using an advanced dual metal CMOS technology. Four bits of data from two sources can be selected using the common select input. The four buffered outputs present the select.
