VCC = 5V,TA = 25°C
DESCRIPTION:
The FCT16827AT/BT/CT/ET and FCT162827AT/BT/CT/
ET 20-bit buffers are built using advanced dual metal CMOS
technology. These 20-bit bus drivers provide high-perfor-
mance bus interface buffering for wide data/address paths or
busses carrying parity. Two pair of NAND-ed output enable
controls offer maximum control flexibility and are organized to
operate the device as two 10-bit buffers or one 20-bit buffer.
Flow-through organization of signal pins simplifies layout. All
inputs are designed with hysteresis for improved noise mar-
gin.
The FCT16827AT/BT/CT/ET are ideally suited for driving
high capacitance loads and low impedance backplanes. The
output buffers are designed with power off disable capability
to allow "live insertion" of boards when used as backplane
drivers.
The FCT162827AT/BT/CT/ET 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. The
FCT162827AT/BT/CT/ET are plug-in replacements for the
FCT16827AT/BT/CT/ET and ABT16827 for on-board inter-
face applications.

NOTES:
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 (fCPNCP/2 + fiNi)
ICC = Quiescent Current (ICCL, ICCH and ICCZ)
∆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)
NCP = Number of Clock Inputs at fCP
fi = Input Frequency
Ni = Number of Inputs at fi
