PI74FCT244T/2244T PI74FCT541T/2541T Fast CMOS Octal Buffer/Line Drivers Features 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 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 Description Pericom Semiconductor’s PI74FCT244T/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 located on one side of the package, while outputs are on the opposite side, allowing for a much simpler and denser board layout. 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.
