FAST CMOS 16-BIT

IDT74FCT162374AT/CT/ET

FEATURES:

DESCRIPTION:

• 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

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.TheOutputEnable(xOE)andclock(xCLK)controlsareorganizedto

1. For conditions shown as Min. or Max., use appropriate value specified under Electrical Characteristics for the applicable device type.

2. Typical values are at VCC = 5.0V, +25°C ambient.

3. Per TTL driven input (VIN = 3.4V). All other inputs at VCC or GND.

4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.

5. Values for these conditions are examples of the ICC formula. These limits are guaranteed but not tested.

6. IC = IQUIESCENT + IINPUTS + IDYNAMIC

IC = ICC + ΔICC DHNT + ICCD (fCPNCP/2 + fiNi)

ICC = Quiescent Current (ICCL, ICCH and ICCZ)

ΔICC = Power Supply Current for a TTL High Input (VIN = 3.4V)

DH = Duty Cycle for TTL Inputs High

NT = Number of TTL Inputs at DH

ICCD = Dynamic Current caused by an Input Transition Pair (HLH or LHL)

fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices)

NCP = Number of Clock Inputs at fCP

fi = Input Frequency

Ni = Number of Inputs at fi
