IDT54/74FCT16374AT/CT/ET FAST CMOS 16-BIT REGISTER (3-STATE) MILITARY AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS 16-BIT REGISTER (3-STATE) IDT54/74FCT16374AT/CT/ET FEATURES: DESCRIPTION: * * * * * The FCT16374T 16-bit edge-triggered D-type register is built using advanced dual metal CMOS technology. These high-speed, low-power registers are ideal for use as buffer registers for data synchronization and storage. The Output Enable (xOE) and clock (xCLK) controls are organized to operate each device as two 8-bit registers or one 16-bit register with common clock. Flow-through organization of signal pins simplifies layout. All inputs are designed with hysteresis for improved noise margin. The FCT16374T is ideally suited for driving high-capacitance loads and low-impedance backplanes. The output buffers are designed with power off disable capability to allow "live insertion" of boards when used as backplane drivers. * * * * * 0.5 MICRON CMOS Technology High-speed, low-power CMOS replacement for ABT functions Typical tSK(o) (Output Skew) < 250ps Low input and output leakage 1A (max.)
