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 (OE) is LOW. When OE 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.
