CY74FCT245TSOCG4

Overview

The CY74FCT245TSOCG4 is an octal bus transceiver from the Texas Instruments FCT logic series, housed in a 20-pin SOIC package. It operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output levels. The device features three-state outputs with a low-level output current of 64 mA and a high-level output current of -32 mA. Propagation delay is specified at 7 ns. It functions as a non-inverting transceiver with eight channels per circuit, operating across a temperature range of -40°C to +85°C.

Feature Summary

• Provides bidirectional data transmission via an octal bus architecture with three-state outputs for effective bus line management.

Applications

• High-speed data transfer between microprocessors and memory modules
• Clock drivers and buffer applications in digital systems
• Bidirectional bus architectures requiring controlled signal directionality

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status against the manufacturer's latest documentation. Confirm the package type matches the required SOIC-20 footprint for PCB layout. Ensure the ordering information aligns with the intended tube packaging quantity if applicable. Cross-reference the datasheet revision date to confirm electrical characteristics remain unchanged.

Selection Notes

Select this component when an octal bus transceiver with FCT speed and CMOS compatibility is required. The 64 mA sink current capability supports moderate capacitive loads without external buffering. The wide operating voltage range ensures compatibility with standard 5 V logic systems. Verify that the 7 ns propagation delay meets the timing constraints of the target application interface.

Part Context

This part belongs to the CY74FCT245T family of octal bus transceivers manufactured by Texas Instruments. The 'G4' suffix typically denotes a lead-free and RoHS-compliant version of the standard CY74FCT245TSOC device. It shares functional pinouts and electrical specifications with other variants in the 74FCT245 series, differing primarily in material composition and environmental compliance certifications.

Replacement Considerations

CY74FCT245TSOC is the standard equivalent part number. CY74FCT245ATSOCT is a tape-and-reel variant of the same logical function. CY74FCT245CTSOC is another tube-packaged alternative within the same series.
