PI74FCT241ATQ

Buffers, Drivers, Receivers, Transceivers Overview

The PI74FCT241ATQ is an octal buffer/line driver manufactured by Diodes Incorporated using advanced CMOS technology. It features true (non-inverting) outputs and a 25-ohm series resistor on all outputs to reduce noise from reflections. The device operates within an industrial temperature range of -40°C to +85°C and supports TTL input and output levels. It utilizes two active-low output enable inputs, OEA and OEB, for control. The component is housed in a 20-pin QSOP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ATQ' against official datasheets to confirm the exact package type and temperature grade. Ensure compatibility with existing board layouts as this device is pin-compatible with older bipolar FAST Series components. Confirm that the 25-ohm internal series resistors meet the impedance requirements of your specific transmission lines without needing external termination.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when non-inverting buffering is required for high-speed digital signals. The integrated 25-ohm resistors simplify design by removing the need for external terminating resistors. Consider the 20-pin QSOP package dimensions for PCB space constraints. Verify that the TTL voltage levels align with the logic family used in the source circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the PI74FCT series of Fast CMOS octal buffers and line drivers. It is produced by Pericom Semiconductor Corporation, which is now part of Diodes Incorporated. The series is engineered to provide industry-leading speed grades while maintaining low static power consumption. It serves as a modern replacement for legacy bipolar logic families in high-performance systems.
