IDT74FCT162374AT/CT/ET FAST CMOS 16-BIT REGISTER (3-STATE) INDUSTRIAL TEMPERATURE RANGE FAST CMOS 16-BIT REGISTER (3-STATE) IDT74FCT162374AT/CT/ET FEATURES: DESCRIPTION: • • • • • • • • The FCT162374T 16-bit edge-triggered D-type registers are 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 FCT162374T has 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.The FCT162374T are plug-in replacements for the FCT16374T and ABT16374 for on-board bus interface applications. 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 ≤1µA (max.) VCC = 5V ±10% Balanced Output Drivers: ±24mA Reduced system switching noise Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V, TA = 25°C • Available in SSOP and TSSOP packages FUNCTIONAL BLOCK DIAGRAM 1 OE 2 OE 1 CLK 2 CLK 1D 1 D 2D 1 D 1O 1 2O 1 C C TO SEVEN OTHER CHANNELS TO SEVEN OTHER CHANNELS The IDT logo is a registered trademark of Integrated Device Technology, Inc.
