• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using
machine model (C = 200pF, R = 0)
• VCC = 3.3V ± 0.3V, Normal Range, or VCC = 2.7V to 3.6V, Extended
Range
• CMOS power levels (0.4μ W typ. static)
μ
• Rail-to-rail output swing for increased noise margin
• Low Ground Bounce (0.3V typ.)
• Inputs (except I/O) can be driven by 3.3V or 5V components
• Available in SSOP and TSSOP packages
The FCT163373 16-bit transparent D-type latches are built using
advanced dual metal CMOS technology. These high-speed, low-power
latches are ideal for temporary storage of data. They can be used for
implementing memory address latches, I/O ports, and bus drivers. The
Output Enable and Latch Enable controls are organized to operate each
device as two 8-bit latches or one 16-bit latch. Flow-through organization
of signal pins simplifies layout. All inputs are designed with hysteresis for
improved noise margin.
The inputs of FCT163373 can be driven from either 3.3V or 5V devices.
This feature allows the use of these transparent latches as translators in a
mixed 3.3V/5V supply system. With xLE inputs high, the FCT163373 can
be used as a buffer to connect 5V components to a 3.3V bus.
