IDT54/74FCT374T/AT/CT FAST CMOS OCTAL D REGISTER (3-STATE) MILITARY AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS OCTAL D REGISTER (3-STATE) FEATURES: * * * * * * * * * IDT54/74FCT374T/AT/CT DESCRIPTION: Std., A, and C grades Low input and output leakage 1A (max.) CMOS power levels True TTL input and output compatibility: - VOH = 3.3V (typ.) - VOL = 0.3V (typ.) High Drive outputs (-15mA IOH, 48mA IOL) Meets or exceeds JEDEC standard 18 specifications Military product compliant to MIL-STD-883, Class B and DESC listed (dual marked) Power off disable outputs permit "live insertion" Available in the following packages: - Industrial: SOIC, SSOP, QSOP, TSSOP - Military: CERDIP, LCC The FCT374T 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. 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.
