DESCRIPTION:
• A, C, and D grades
The FCT157T is a high-speed quad 2-input multiplexer built using an
• Low input and output leakage 1µA (max.)
advanced dual metal CMOS technology. Four bits of data from two sources
• CMOS power levels
can be selected using the common select input. The four buffered outputs
• True TTL input and output compatibility:
present the selected data in the true (non-inverting) form.
– VOH = 3.3V (typ.)
The FCT157T has a common, active-low, enable input. When the
– VOL = 0.3V (typ.)
enable input is not active, all four outputs are held low. A common application
• High Drive outputs (-15mA IOH, 48mA IOL)
• Meets or exceeds JEDEC standard 18 specifications
R• Power off disable outputs permit "live insertion"
T• Available in SOIC and QSOP packages
of FCT157T is to move data from two different groups of registers to a
common bus. Another application is as a function generator. The FCT157T
can generate any four of the 16 different functions of two variables with one
variable common.

NOTES:
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. No terminal voltage may exceed
Vcc by +0.5V unless otherwise noted.
2. Inputs and Vcc terminals only.
3. Output and I/O terminals only.
