FAST CMOS
8-INPUT MULTIPLEXER
Integrated Device Technology, Inc.
FEATURES:
• Std., A, and C speed grades
• Low input and output leakage ≤1µA (max.)
• Extended commercial range of –40°C to +85°C
• CMOS power levels
• True TTL input and output compatibility
– VOH = 3.3V (typ.)
DESCRIPTION:
TheIDT54/74FCT151T/AT/CTarehigh-speed8-inputmul-
tiplexers built using an advanced dual metal CMOS technol-
ogy. They select one bit of data from up to eight sources under
the control of three select inputs. Both assertion and negation
outputs are provided.
TheIDT54/74FCT151T/AT/CThasacommonActive-LOW
enable(E)input. WhenEisLOW, datafromoneofeightinputs
is routed to the complementary outputs according to the 3-bit
code applied to the Select (S0-S2) inputs. A common appli-
cation of the ‘FCT151 is data routing from one of eight
sources.
– VOL = 0.3V (typ.)
• High drive outputs (-15mA IOH, 48mA IOL)
• Power off disable outputs permit “live insertion”
• Meets or exceeds JEDEC standard 18 specifications
• Product available in Radiation Tolerant and Radiation
Enhanced versions
• Military product compliant to MIL-STD-883, Class B
and DESC listed (dual marked)
• Available in DIP, SOIC, CERPACK and LCC packages

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-
INGS may cause permanent damage to the device. This is a stress rating
onlyandfunctionaloperationofthedeviceattheseoranyotherconditions
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

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 and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the short circuit test should not exceed one second.
4. The test limit for this parameter is ±5µA at TA = -55°C.

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 + fiNO)
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
NO = Number of Inputs at fi
All currents are in milliamps and all frequencies are in megahertz.
