DESCRIPTION:

The FCT257T is a high-speed quad 2-input multiplexer 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 selected data in the true (non-inverting) form.

FEATURES:

? Std., A, C, and D grades

? Low input and output leakage ≤1?A (max.)

? CMOS power levels

? True TTL input and output compatibility:

– VOH = 3.3V (typ.)

– VOL = 0.3V (typ.)

? High Drive outputs (-15mA IOH, 48mA IOL)

? Meets or exceeds JEDEC standard 18 specifications

? Military product compliant to MIL-STD-883, Class B and DESC

listed (dual marked)

? Power off disable outputs permit live insertion

? Available in the following packages:
