DESCRIPTION:
consist transceiver with 3-state D-type flip-flops control circuitry arranged multiplexed transmission data directly from data from internal storage registers. FCT652T/FCT2652T utilize signals control transceiver functions. FCT646T/FCT2646T/ FCT648T utilize enable control direction (DIR) pins control transceiver functions. control pins provided select either realtime stored data transfer. circuitry used select control will eliminate typical decoding glitch that occurs multiplexer during transition between stored realtime data. input level selects real-time data HIGH selects stored data. Data data bus, both, stored internal flip-flops LOW-to-HIGH transitions appropriate clock pins (CPAB CPBA), regardless select enable control pins. FCT26xxT have balanced drive outputs with current limiting resistors. This offers ground bounce, minimal undershoot controlled output fall times-reducing need external series terminating resistors. FCT2xxxT parts plug-in replacements FCTxxxT parts.
