FEATURES
DESCRIPTION
• IDT54/74FCT373/533/573 equivalent to FAST speed
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
The IDT54/74FCT373/A/C, IDT54/74FCT533/A/C and
IDT54/74FCT573/A/C are octal transparent latches 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.

1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a stress
rating 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 VCC by +0.5V unless otherwise noted.
2. Input and VCC terminals only.
