CY74FCT2240ATQC

Overview

The CY74FCT2240ATQC is an octal bus driver from the FCT logic series, manufactured by Texas Instruments. It features non-inverting outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device provides three-state outputs with a maximum high-level output current of -15 mA and a low-level output current of 12 mA. Propagation delay is specified at 4.6 ns at 5 V under a 50 pF load. It functions in temperatures from -40 °C to +85 °C and is housed in a QSOP-20 surface-mount package.

Feature Summary

• Octal configuration providing eight independent non-inverting signal paths for parallel data transmission.
• Three-state output capability allowing multiple drivers to share a common bus without electrical conflict.
• Fast CMOS technology enabling high-speed signal propagation with low static power consumption.

Applications

• High-speed digital bus architectures requiring signal buffering and direction control.
• Memory interface circuits where data isolation and drive strength are critical.
• Microprocessor-based systems utilizing parallel data buses for communication between components.

Procurement Notes

Verify the specific suffix 'ATQC' against the manufacturer's official datasheet to confirm the QSOP-20 package type and temperature grade. Ensure compatibility with system voltage levels, as this component requires a strict 4.75 V to 5.25 V supply range. Confirm moisture sensitivity handling requirements during assembly to prevent package damage.

Selection Notes

Select this component when an octal, non-inverting buffer with three-state control is required for 5 V logic systems. Compare drive current specifications against load requirements to ensure signal integrity. Consider the QSOP-20 package dimensions if board space is constrained relative to other FCT series options like the SOIC variant.

Part Context

This part belongs to the CY74FCT family, representing Cypress Semiconductor's legacy products now managed by Texas Instruments. The FCT series bridges the performance gap between standard TTL and advanced CMOS technologies, offering faster switching speeds than classic 74F logic while maintaining compatible pinouts and voltage levels for easy integration into existing designs.

Replacement Considerations

The SN74FCT2240 is functionally equivalent but may differ in packaging or manufacturing origin. Verify that any substitute maintains the same three-state output characteristics and voltage operating range to ensure circuit compatibility.
