These high-speed, low-power transceivers are ideal for synchronous communication between two busses (A and B). The Direction and Output Enable controls 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. The FCT16245T FCT16245T is ideally suited for driving high-capacitance loads and lowimpedance backplanes. The output buffers are designed with power off disable capability to allow "live insertion" of boards when used as backplane drivers. · · · · 0.5 MICRON CMOS Technology High-speed, low-power CMOS replacement for ABT functions Typical tSK(o) (Output Skew) < 250ps Low input and output leakage 1µA (max.)
