ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) Balanced Output Drivers (±24mA) Reduced system switching noise Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V, TA = 25°C Power off disable outputs permit “live insertion” Available in SSOP and TSSOP packages The FCT162952T 16-bit registered transceiver is built using advanced dual metal CMOS technology. These high-speed, low-power devices are organized as two independent 8-bit D-type registered transceivers with separate input and output control for independent control of data flow in either direction. For example, the A-to-B Enable (xCEAB) must be low to enter data from the A port. xCLKAB controls the clocking function. When xCLKAB toggles from low-to-high the data present on the A port will be clocked into the register. xOEAB performs the output enable function on the B port. Data flow from the B port to A port is similar but requires using xCEBA, xCLKBA, and xOEBA inputs. Full 16-bit operation is achieved by tying the control pins of the independent transceivers together. The FCT162952T have balanced output drive with current limiting resistors. This offers low ground bounce, minimal undershoot, and controlled output fall times–reducing the need for external series terminating resistors. The FCT162952T is a plug-in replacement for the FCT16952T and ABT16952 for on-board bus interface applications.
