Features, Applications

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 1A (max.) ESD > 2000V per MIL-STD-883, Method > 200V using machine model = 0) High drive outputs (32mA IOH, 64mA IOL) Power off disable outputs permit "live insertion" Typical VOLP (Output Ground Bounce) 1.0V at VCC = 25C Available in the following packages: Industrial: SSOP, TSSOP, TVSOP Military: CERPACK

The FCT16245T 16-bit transceiver is built using advanced dual metal CMOS technology. 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 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.
