IDT74FCT863A/B HIGH-PERFORMANCE CMOS 9-BIT NON-INVERTING TRANSCEIVER COMMERCIAL TEMPERATURE RANGE HIGH-PERFORMANCE CMOS 9-BIT NON-INVERTING TRANSCEIVER FEATURES: IDT74FCT863A/B DESCRIPTION: • Equivalent to AMD's Am29861-64 bipolar registers in pinout/ function, speed, and output drive over full temperature and voltage supply extremes • IDT74FCT863A equivalent to FAST™ speed • IDT74FCT863B 25% faster than FAST • High-speed symmetrical bidirectional transceivers • IOL = 48mA • Clamp diodes on all inputs for ringing suppression • CMOS power levels (1mW typ. static) • TTL input and output level compatible • CMOS output level compatible • Substantially lower input current levels than AMD's bilopar µA max.) Am29800 series (5µ • Available in SOIC package The IDT74FCT800 series is built using an advanced dual metal CMOS technology. The IDT74FCT863 9-bit transceivers have NAND-ed output enables for maximum control flexibility. All of the IDT74FCT800 high-performance interface family is designed for high-capacitance load drive capability while providing low-capacitance bus loading at both inputs and outputs. All inputs have clamp diodes and all outputs are designed for low-capacitance bus loading in the highimpedance state.
