FEATURES:
DESCRIPTION:
• 0.5 MICRON CMOS Technology
The FCT162245T 16-bit transceiver is built using advanced dual metal
CMOStechnology. These high-speed, low-powertransceivers are idealfor
synchronouscommunicationbetweentwobuses(AandB).TheDirectionand
OutputEnablecontrolsoperatethesedevicesaseithertwoindependent8-bit
transceiversorone16-bittransceiver.Thedirectioncontrolpin(xDIR)controls
thedirectionofdataflow.Theoutputenablepin(xOE)overridesthedirection
control and disables both ports. All inputs are designed with hysteresis for
improvednoisemargin.
• High-speed, low-power CMOS replacement for ABT functions
• Typical tSK(o) (Output Skew) < 250ps
• Low input and output leakage ≤ 1µA (max.)
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using
machine model (C = 200pF, R = 0)
• Balanced Output Drivers:
– ±24mA(industrial)
– ±16mA(military)

Thisofferslowgroundbounce,minimalundershoot, andcontrolledoutputfall
times–reducing the need for external series terminating resistors. The
FCT162245Tisaplug-inreplacementfortheFCT16245TandABT16245for
on-boardinterfaceapplications.
• Reduced system switching noise
• Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V,
TA = 25°C
• Available in the following packages:
– Industrial: SSOP, TSSOP
– Military:CERPACK

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.
2. All device terminals except FCT162XXXT AND FCT166XXXT (A-Port) Output and
I/O terminals.

1. For conditions shown as Min. or Max., 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 + ΔICC DHNT + ICCD (fCPNCP/2 + fiNi)
ICC = Quiescent Current (ICCL, ICCH and ICCZ)
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)
