• Features for FCT827T:
– A, B, C and D speed grades
– High drive outputs (-15mA IOH, 48mA IOL)
• Features for FCT2827T:
– A, B and C speed grades

– Reduced system switching noise
The FCT827T is built using an advanced dual metal CMOS
technology.
The FCT827T/FCT2827T 10-bit bus drivers provide highperformance bus interface buffering for wide data/address
paths or buses carrying parity. The 10-bit buffers have NANDed output enables for maximum control flexibility.
All of the FCT827T high-performance interface family are
designed for high-capacitance load drive capability, while
providing low-capacitance bus loading at both inputs and
outputs. All inputs have clamp diodes to ground and all outputs
are designed for low-capacitance bus loading in high-impedance state.
The FCT2827T 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. FCT2827T parts are
plug-in replacements for FCT827T parts.

NOTES:
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.

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.
