DESCRIPTION:

The FCT373T/FCT2373T, FCT533T and FCT573T/

FCT2573T are octal transparent latches built using an ad-

vanced dual metal CMOS technology. These octal latches

have 3-state outputs and are intended for bus oriented appli-

cations. 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 (

) is LOW. When

is HIGH, the

bus output is in the high- impedance state.

The FCT2373T and FCT2573T have balanced drive out-

puts with current limiting resistors. This offers low ground

bounce, minimal undershoot and controlled output fall times-

reducing the need for external series terminating resistors.

The FCT2xxxT parts are plug-in replacements for FCTxxxT

parts.
