PI74FCT244T/2244T

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.
