PI74FCT541T/2541T
Fast CMOS Octal Buffer/Line Drivers
Features
Description
• PI74FCT244/541T and PI74FCT2244/2541T are pin
compatible with bipolar Fast Series at a higher speed and
lower power consumption
• 25Ω series resistor on all outputs (FCT2XXX only)
• TTL input and output levels
PericomSemiconductor’sPI74FCT244T/541T and P174FCT2244/
2541T are 8-bit wide driver circuits, designed to be used in
applications requiring high-speed and high-output drive. Ideal
applications would include bus drivers, memory drivers, address
drivers, and system clock drivers.
The PI74FCT541 and 2541T provide similar driver capabilities,
but have their pins physically grouped by function. All inputs are
locatedononesideofthepackage,whileoutputsareontheopposite
side, allowing for a much simpler and denser board layout.
• Low ground bounce outputs
• Extremely low static power
• Hysteresis on all inputs
• Industrial operating temperature range: –40°C to +85°C
• Packaging (Pb-free & Green available):
– 20-pin 173-mil wide plastic TSSOP (L)
– 20-pin 209-mil wide plastic SSOP (H)
– 20-pin 150-mil wide plastic QSOP (Q)
– 20-pin 150-mil wide plastic TQSOP (R)
– 20-pin 300-mil wide plastic SOIC (S)
• Device models available upon request
All PI74FCT2XXX devices have a built-in 25Ω series resistor on
all outputs to reduce noise because of reflections, thus eliminating
the need for an external terminating resistor.

1. For Max. or Min. conditions, 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 + ΔICC DHNT + ICCD (fCP/2 + fINI)
ICC = Quiescent Current
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)
fI = Input Frequency
NI = Number of Inputs at fI
All currents are in milliamps and all frequencies are in megahertz.
