IDT74FCT534AT/CT FAST CMOS OCTAL D REGISTER (3-STATE) INDUSTRIAL TEMPERATURE RANGE FAST CMOS OCTAL D REGISTER (3-STATE) IDT74FCT534AT/CT FEATURES: DESCRIPTION: − − − The FCT534T 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) input is low, the eight outputs are enabled. When the OE input is high, the outputs are in the high-impedance state. − − − − − Low input and output leakage ≤1µ A (max.) CMOS power levels True TTL input and output compatibility • VOH = 3.3V (typ.) • VOL = 0.3V (typ.) Meets or exceeds JEDEC standard 18 specifications A and C speed grades High drive outputs (-15mA IOH, 48mA IOL) Power off disable outputs permit “live insertion” Available in SOIC and QSOP packages 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.
