IDT54/74FCT374/A/C FAST CMOS OCTAL D REGISTERS (3-STATE) MILITARY AND COMMERCIAL TEMPERATURE RANGES FAST CMOS OCTAL D REGISTERS (3-STATE) IDT54/74FCT374/A/C FEATURES: DESCRIPTION: - - - - - - - - - - The FCT374 is an 8-bit register built using an advanced dual metal CMOS technology. These registers consist of eight D-type flip-flops with a buffered common clock and buffered 3-state output control. When the output enable (OE) is low, the eight outputs are enabled. When the OE input is high, the outputs are in the high-impedance state. IDT54/74FCT374 equivalent to FASTTM speed and drive IDT54/74FCT374A up to 30% faster than FAST IDT54/74FCT374C up to 50% faster than FAST IOL = 48mA (commercial) and 32mA (military) CMOS power levels (1mW typ. static) Edge triggered master/slave, D-type flip-flops Buffered common clock and buffered common three-state control Military product compliant to MIL-STD-883, Class B Meets or exceeds JEDEC Standard 18 specifications Available in the following packages: * Commercial: SOIC * Military: CERDIP, LCC, CERPACK Input data meeting the set-up and hold time requirements of the D inputs is transferred to the O outputs on the low-to-high transition of the clock input. The FCT374 has non-inverting outputs with respect to the data at the D inputs.
