FEATURES:
DESCRIPTION:
•
•
•
•
The FCT373Tis an octal transparent latch built using an advanced dual
metal CMOS technology. These octal latches have 3-state outputs and are
intended for bus oriented applications. The flip-flops appear transparent to
the data when Latch Enable (LE) is high. When LE is low, the data that meets
the set-up time is latched. Data appears on the bus when the Output Enable
(OE) is low. When OE is high, the bus output is in the high-impedance state.
