DESCRIPTION
The FCT374T/FCT2374T, FCT534T and FCT574T/
FCT2574T are 8-bit registers built using an advanced dual
metal CMOS technology. These registers consist of eight D-
type flip-flops with a buffered common clock and buffered 3-
state 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-to-
HIGH 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.

1. For conditions shown as Max. or Min., 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 + ∆ICC DHNT + ICCD (fCP/2 + fiNi)
ICC = Quiescent Current
∆ICC = 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)
fi = Input Frequency
Ni = Number of Inputs at fi
All currents are in milliamps and all frequencies are in megahertz.
