DESCRIPTION
The IDT54/74FCT373/A/C, IDT54/74FCT533/A/C and
IDT54/74FCT573/A/C are octal transparent latches built us-
ing 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.
