IDT74FCT16374AT/CT/ET FAST CMOS 16-BIT REGISTER (3-STATE) INDUSTRIAL TEMPERATURE RANGE FAST CMOS 16-BIT IDT74FCT16374AT/CT/ET REGISTER (3-STATE) FEATURES: DESCRIPTION: 0.5 MICRON CMOS Technology The FCT16374T 16-bit edge-triggered D-type register is built using High-speed, low-power CMOS replacement for ABT functions advanced dual metal CMOS technology. These high-speed, low-power Typical tSK(o) (Output Skew) < 250ps registers are ideal for use as buffer registers for data synchronization and Low input and output leakage 1A (max.) storage. The Output Enable (xOE) and clock (xCLK) controls are organized ESD > 2000V per MIL-STD-883, Method 3015 > 200V using to operate each device as two 8-bit registers or one 16-bit register with machine model (C = 200pF, R = 0) common clock. Flow-through organization of signal pins simplifies layout. All VCC = 5V 10% inputs are designed with hysteresis for improved noise margin. High drive outputs (32mA IOH, 64mA IOL) The FCT16374T is ideally suited for driving high-capacitance loads and Power off disable outputs permit live insertion low-impedance backplanes. The output buffers are designed with power off Typical VOLP (Output Ground Bounce) < 1.0V at VCC = 5V, disable capability to allowlive insertio of boards when used as backplane TA = 25C drivers.
