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.

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
