CY74FCT541ATQCT

Overview

The CY74FCT541ATQCT is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum load capacitance of 50 pF. The device provides high drive capability with output currents of -32 mA for high state and 64 mA for low state. Propagation delay is specified at 4.8 ns at 5 V. It utilizes CMOS logic technology and is housed in a 20-SSOP package with a width of 3.90 mm. The component functions as a unidirectional bus driver with dual output enable control.

Feature Summary

• Provides eight non-inverting buffered channels with true output polarity for signal integrity maintenance.
• Features three-state outputs controlled by dual enable inputs to facilitate bus-oriented architectures.
• Delivers strong drive performance suitable for driving transmission lines and heavy capacitive loads.

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffering
• Capacitively loaded lines

Procurement Notes

Verify the specific suffix 'TQC' confirms the 20-SSOP package variant and lead-free status. Confirm RoHS compliance and moisture sensitivity level requirements against storage conditions. Ensure the ordering part number matches the exact temperature grade and package dimensions required for the PCB footprint.

Selection Notes

Select this component when an octal buffer with three-state capability is required for 5V systems. Compare propagation delay specifications against other FCT series variants if timing constraints are critical. Verify that the SSOP package dimensions fit the available board space compared to SOIC alternatives.

Part Context
