DESCRIPTION:
• 0.5 MICRON CMOS Technology
TheFCT16373T16-bit transparentD-typelatchis builtusingadvanceddual
metalCMOStechnology. Thesehigh-speed, low-powerlatchesareidealfor
temporarystorageofdata.Theycanbeusedforimplementingmemoryaddress
latches,I/Oports,andbusdrivers.TheOutputEnableandLatchEnablecontrols
areorganizedtooperateeachdeviceastwo8-bitlatches,orone16-bitlatch.
Flow-throughorganizationofsignalpinssimplifieslayout.Allinputsaredesigned
withhysteresisforimprovednoisemargin.
• 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)
• VCC = 5V ±10%
• High drive outputs (–32mA IOH, 64mA IOL)
• Power off disable outputs permit “live insertion”
• Typical VOLP (Output Ground Bounce) < 1.0V at VCC = 5V,
TA = 25°C
TheFCT16373Tisideallysuitedfordrivinghigh-capacitanceloadsandlow-
impedancebackplanes.Theoutputbuffersaredesignedwithpoweroffdisable
capabilitytoallow"liveinsertion"ofboardswhenusedasbackplanedrivers.
• Available in the following packages:

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.

NOTES:
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. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
4. Duration of the condition can not exceed one second.
5. This test limit for this parameter is ±5µA at TA = –55°C.

NOTES:
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 + ∆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
