FEATURES
• IDT54/74FCT373/533/573 equivalent to FAST speed
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
latcheshave3-stateoutputsandareintendedforbusoriented
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 OEis HIGH, the
bus output is in the high-impedance state.
and drive
• IDT54/74FCT373A/533A/573A up to 30% faster than
FAST
• Equivalent to FAST output drive over full temperature
and voltage supply extremes
• IOL = 48mA (commercial) and 32mA (military)
• CMOS power levels (1mW typ. static)
• Octal transparent latch with 3-state output control
• JEDEC standard pinout for DIP and LCC
• Product available in Radiation Tolerant and Radiation
Enhanced versions
• Military product compliant to MIL-STD-883, Class B
