REGISTERS (3-STATE)
IDT54/74FCT574T/AT/CT
FEATURES:
DESCRIPTION:
• Std., A, and C grades
• Low input and output leakage ≤1µA (max.)
• CMOS power levels
• True TTL input and output compatibility:
– VOH = 3.3V (typ.)
The FCT574T is an 8-bit register built using an advanced dual metal
CMOStechnology.Theseregisters consistofeightD-typeflip-flops witha
bufferedcommonclockandbuffered3-stateoutputcontrol.Whentheoutput
enable(OE)inputis low,theeightoutputs areenabled.WhentheOEinput
is high,the outputs are inthe high-impedance state.
– VOL = 0.3V (typ.)

istransferredtotheQoutputsonthelow-to-hightransitionoftheclockinput.
• High Drive outputs (-15mA IOH, 48mA IOL)
• Meets or exceeds JEDEC standard 18 specifications
• Military product compliant to MIL-STD-883, Class B and DESC
listed (dual marked)
• Power off disable outputs permit "live insertion"
• Available in the following packages:
– Industrial: SOIC, QSOP
– Military: CERDIP, LCC

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability. No terminal voltage may exceed
Vcc by +0.5V unless otherwise noted.

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 ΔICC formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ΔICC DHNT + ICCD (fCP/2+ fiNi)
ICC = Quiescent Current
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)
fi = Output Frequency
Ni = Number of Outputs at fi
All currents are in milliamps and all frequencies are in megahertz.
