FAST CMOS OCTAL

TRANSPARENT LATCH

DESCRIPTION:

The FCT2373T is 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.

The FCT2373T has balanced drive outputs with current limiting resis-

tors. This offers low ground bounce, minimal undershoot and controlled

output fall times-reducing the need for external series terminating resistors.

The FCT2373T parts are plug-in replacements for FCT373T parts.
