DESCRIPTION:
• 0.5 MICRON CMOS Technology
• ESD > 2000V per MIL-STD-883, Method 3015;
> 200V using machine model (C = 200pF, R = 0)
• 25 mil Center SSOP Packages
• Extended commercial range of -40°C to +85°C
• VCC = 3.3V ±0.3V, Normal Range or
VCC = 2.7V to 3.6V, Extended Range
• CMOS power levels (0.4µW typ. static)
• Rail-to-Rail output swing for increased noise margin
• Military product compliant to MIL-STD-883, Class B
The FCT3573/A 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.

NOTES:
1. See test circuit and waveforms.
2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. Propagation Delays and Enable/Disable times are with VCC = 3.3V ±0.3V, Normal Range. For VCC = 2.7V to 3.6V, Extended Range, all Propagation Delays
and Enable/Disable times should be degraded by 20%.
