INDUSTRIAL TEMPERATURE RANGE
3.3V CMOS OCTAL D REGISTER (3-STATE)
FEATURES: DESCRIPTION:
IDT74FCT3574/A
* 0.5 MICRON CMOS Technology * ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) * VCC = 3.3V 0.3V, Normal Range * VCC = 2.7V to 3.6V, Extended Range * CMOS power levels (0.4W typ. static) * Rail-to-Rail output swing for increased noise margin * Available in QSOP, SOIC, and TSSOP packages
The FCT3574/A are 8-bit registers 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 OE input is low, the eight outputs are enabled. When the OE input is high, the outputs are in the high-impedance state. Input data meeting the set-up and hold time requirements of the D inputs is transferred to the Q outputs on the low-to-high transition of the clock input.
