FAST CMOS OCTAL

TRANSPARENT LATCH

DESCRIPTION:

The FCT573Tis 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

thedatawhenLatchEnable(LE)ishigh. WhenLEislow,thedatathatmeets

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.
