PI74FCT574T
Fast CMOS Octal D Registers (3-State)
Features:
Description:
• Pin compatible with bipolar FAST™ Series at a higher speed
and lower power consumption
PericomSemiconductor’sPI74FCT374T/574T are8-bitwideoctal
registers designed with eight D-type flip-flops with a buffered
common clock and buffered 3-state outputs. When output enable
(OE)isLOW,theoutputsareenabled.WhenOEisHIGH,theoutputs
are in the high impedance state. Input data meeting the setup and
holdtimerequirementsoftheDinputsistransferredtotheOoutputs
on the LOW-to-HIGH transition of the clock input. Device models
available upon request.
• TTL input and output levels
• Low ground bounce outputs
• Extremelylowstaticpower
• Hysteresis on all inputs
• Industrial operating temperature range: –40°C to +85°C
• Packaging(Pb-free&Greenavailable):

Notes:
1. For Max. or Min. conditions, 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 test should not exceed one second.
4. This parameter is determined by device characterization but is not production tested.

Notes:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device.
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 = 3.4 V)
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
NI = Number of Inputs at fI
All currents are in milliamps and all frequencies are in megahertz.
