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)
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, TSSOP and TVSOP Packages
The FCT163245/A/C 16-bit transceivers are built using advanced dual
metal CMOS technology. These high-speed, low-power transceivers are
ideal for asynchronous communication between two buses (A and B). The
Direction and Output Enable controls are designed to operate these devices
as either two independent 8-bit transceivers or one 16-bit transceiver. The
direction control pin (xDIR) controls the direction of data flow. The output
enable pin (xOE) overrides the direction control and disables both ports.
All inputs are designed with hysteresis for improved noise margin.
