DESCRIPTION:
FCT16652T/AT/CT/ET FCT162652T/AT/CT/ET 16-bit registered transceivers built using advanced dual metal CMOS technology. These high-speed, low-power
vices organized independent 8-bit transceivers with 3-state D-type registers. example, xOEAB xOEBA signals control transceiver functions. xSAB xSBA control pins provided select either real time stored data transfer. circuitry used select control will eliminate typical decoding glitch that occurs multiplexer during transition between stored real time data. input level selects real-time data HIGH level selects stored data. Data data bus, both, stored internal D-flip-flops LOW-to-HIGH transitions appropriate clock pins (xCLKAB xCLKBA), regardless select enable control pins. Flow-through organization signal pins simplifies layout. inputs designed with hysteresis improved noise margin. FCT16652T/AT/CT/ET ideally suited driving high capacitance loads low-impedance backplanes. output buffers designed with power disable capability allow "live insertion" boards when used backplane drivers. FCT162652T/AT/CT/ET have balanced output drive with current limiting resistors. This offers ground bounce, minimal undershoot, controlled output fall times-reducing need external series terminating resistors. FCT162652T/AT/CT/ET plug-in replacements FCT16652T/AT/CT/ET ABT16652 on-board interface applications.
