CY74FCT2652CTQCTE4

Overview

The CY74FCT2652CTQCTE4 is an octal bus transceiver with register and 3-state outputs from the FCT logic series. It operates within a supply voltage range of 4.75 V to 5.25 V. The device features non-inverting polarity and accepts TTL input levels while providing TTL output levels. Key electrical parameters include a maximum propagation delay of 5.7 ns at 5 V, a low-level output current of 64 mA, and a high-level output current of -32 mA. It is housed in a 24-pin QSOP package and supports surface mount installation.

Feature Summary

• Integrates octal bus transceiver functionality with built-in register capability for data storage
• Provides 3-state outputs to facilitate direct connection to system buses
• Supports non-inverting signal transmission with TTL-compatible input and output levels

Applications

• High-speed data acquisition systems requiring registered bus interfacing
• Memory buffer applications in industrial control environments
• Communication interface modules utilizing 3-state bus architectures

Procurement Notes

Verify the component status as sources indicate it may be obsolete. Confirm the package designation matches the required 24-pin QSOP or SSOP variant. Ensure moisture sensitivity handling protocols are followed during assembly. Cross-reference the manufacturer part number with official Texas Instruments documentation to validate specifications before integration into designs.

Selection Notes

Select this component when an octal transceiver with internal latching is required for 5 V logic systems. The FCT series offers high speed and low power consumption suitable for dense digital circuits. Consider the 3-state output capability for bidirectional bus sharing. Verify that the operating temperature range of -40 °C to +85 °C meets the environmental requirements of the target application.

Part Context

This part belongs to the CY74FCT family of high-speed CMOS logic devices manufactured by Texas Instruments. The FCT series is designed to provide performance comparable to bipolar LS-TTL but with CMOS power advantages. The specific model integrates transceiver and register functions, distinguishing it from standard unregistered bus drivers in the same logical family.
