IDT54FCT833A

® FAST CMOS PARITY BUS TRANSCEIVER DESCRIPTION: IDT54/74FCT833A IDT54/74FCT833B Integrated Device Technology, Inc. FEATURES: Equivalent to AMD’s Am29833 bipolar parity bus transceiver in pinout/function, speed and output drive over full temperature and voltage supply extremes High-speed bidirectional bus transceiver for processororganized devices IDT54/74FCT833A equivalent to Am29833A speed and output drive IDT54/74FCT833B 30% faster than Am29833A Buffered direction and three-state controls Error flag with open-drain output IOL = 48mA (commercial) and 32mA (military) TTL input and output level compatible CMOS output level compatible Substantially lower input current levels than AMD’s bipolar Am29800 series (5µA max.) Available in plastic DIP, CERDIP, LCC and SOIC Product available in Radiation Tolerant and Radiation Enhanced versions Military product compliant to MIL-STD-883, Class B The IDT54/74FCT833s are high-performance bus transceivers designed for two-way communications. They each contain an 8-bit data path from the R (port) to the T (port), an 8-bit data path from the T (port) to the R (port), and a 9-bit parity checker/generator. The error flag can be clocked and stored in a register and read at the ERR output. The clear (CLR) input is used to clear the error flag register. The output enables OET and OER are used to force the port outputs to the high-impedance state so that the device can drive bus lines directly. In addition, OER and OE...
