Integrated Device Technology, Inc.
FEATURES:
DESCRIPTION:
• IDT54/74FCT299 equivalent to FAST speed
• IDT54/74FCT299A 25% faster than FAST
• IDT54/74FCT299C 35% faster than FAST
• Equivalent to FAST output drive over full temperature
and voltage supply extremes
• IOL = 48mA (commercial) and 32mA (military)
• CMOS power levels (1mW typ. static)
• TTL input and output level compatible
• CMOS output level compatible
The IDT54/74FCT299 and IDT54/74FCT299A/C are built
usinganadvanceddualmetalCMOStechnology. TheIDT54/
74FCT299 and IDT54/74FCT299A/C are 8-input universal
shift/storage registers with 3-state outputs. Four modes of
operation are possible: hold (store), shift left, shift right and
load data. The parallel load inputs and flip-flop outputs are
multiplexed to reduce the total number of package pins.
Additional outputs are provided for flip-flops Q0 and Q7 to
allow easy serial cascading. A separate active LOW Master
Reset is used to reset the register.
• Substantially lower input current levels than FAST
(5µA max.)
• 8-input universal shift register
• JEDEC standard pinout for DIP and LCC
• Product available in Radiation Tolerant and Radiation
Enhanced versions
• Military product compliant to MIL-STD-883, Class B
• Standard Military Drawing# 5962-86862 is listed on this
function. Refer to section 2.

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 +0.5 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 Output 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.
