FAST CMOS OCTAL D REGISTERS (3-STATE) IDT54/74FCT374T/AT/CT/DT - 2374T/AT/CT IDT54/74FCT534T/AT/CT IDT54/74FCT574T/AT/CT/DT - 2574T/AT/CT Integrated Device Technology, Inc. FEATURES: DESCRIPTION * Common features: - Low input and output leakage 1A (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 - Product available in Radiation Tolerant and Radiation Enhanced versions - Military product compliant to MIL-STD-883, Class B and DESC listed (dual marked) - Available in DIP, SOIC, SSOP, QSOP, CERPACK and LCC packages * Features for FCT374T/FCT534T/FCT574T: - Std., A, C and D speed grades - High drive outputs (-15mA IOH, 48mA IOL) * Features for FCT2374T/FCT2574T: - Std., A, and C speed grades - Resistor outputs (-15mA IOH, 12mA IOL Com.) (-12mA IOH, 12mA IOL Mil.) - Reduced system switching noise The FCT374T/FCT2374T, FCT534T and FCT574T/ FCT2574T are 8-bit registers built using an advanced dual metal CMOS technology. These registers consist of eight Dtype flip-flops with a buffered common clock and buffered 3state 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-toHIGH transition of the clock input. The FCT2374T and FCT2574T have balanced output drive with current limiting resistors. This offers low ground bounce, minimal undershoot and controlled output fall times-reducing the need for external series terminating resistors. FCT2xxxT parts are plug-in replacements for FCTxxxT parts.
