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.
