BUS INTERFACE
8-BIT REGISTER
DESCRIPTION:
FEATURES:
The IDTQS74FCT2374T is a high-speed CMOS TTL-compatible 8-bit
• CMOS power levels: <7.5mW static
• Undershoot clamp diodes on all outputs
• True TTL input and output compatibility
• Ground bounce controlled outputs
• Reduced output swing of 0 to 3.5V
• Built-in 25Ω series resistor outputs reduce reflection and other
system noise

transmission lines and reducing system noise. The FCT2374 is a non-
invertingdevice.Allinputshaveclampdiodesforundershootnoisesuppres-
sion. All outputs have ground bounce suppression. Outputs will not load
an active bus when Vcc is removed from the device.
• Std., A and C speed grades with 5.2ns tPD for C
• IOL = 12mA
• Available in SOIC package

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.

NOTES:
1. For conditions shown as Min. or Max., use the appropriate values specified under DC Electrical Characteristics.
2. Per TLL driven input (VIN = 3.4V).
3. For flip-flops, ICCD is measured by switching one of the data input pins so that the output changes every clock cycle. This is a measurement of device power consumption
only and does not include power to drive load capacitance or tester capacitance.
4. 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 Output 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.
