3.3V CMOS OCTAL
TRANSPARENT
LATCH
IDT74FCT3573/A
DESCRIPTION:
FEATURES:
The FCT3573/Aare octaltransparentlatches builtusinganadvanced
dualmetalCMOStechnology.
• 0.5 MICRON CMOS Technology
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using
machine model (C = 200pF, R = 0)
• VCC = 3.3V ±0.3V, Normal Range
• VCC = 2.7V to 3.6V, Extended Range
• CMOS power levels (0.4μW typ. static)
• Rail-to-Rail output swing for increased noise margin
• Available in QSOP package
These octal latches have 3-state outputs and are intended for bus
orientedapplications. The flip-flops appeartransparenttothe data when
LatchEnable (LE)is high. WhenLEis low,the data thatmeets the set-up
time is latched. Data appears onthe bus whenthe OutputEnable (OE)is
low. WhenOE is high, the bus outputis inthe 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.

NOTES:
1. 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/
