Overview
The IDT74FCT543DTQG8 is a non-inverting bus transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.75V to 5.25V and features tri-state outputs with high drive capabilities of 15mA for high state and 64mA for low state. The device contains one functional element comprising eight bits, housed in a 24-QSOP surface-mount package. It supports an operating temperature range from -40°C to 85°C.
Feature Summary
- Provides bidirectional data transfer between two buses using a single control signal.
- Features tri-state outputs to isolate the device when not selected.
- Designed for CMOS technology ensuring compatibility with standard logic families.
Applications
- Memory mapping systems
- Clock drivers
- Bus-oriented architectures
Procurement Notes
Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and pin alignment against the 24-QSOP specification. Check for moisture sensitivity level compliance prior to soldering. Ensure replacement parts match electrical characteristics and pinout definitions exactly.
Selection Notes
Select this component for applications requiring 8-bit wide data transmission with non-inverted logic. Consider the 24-QSOP package constraints for PCB layout. Evaluate thermal performance within the specified -40°C to 85°C ambient range. Verify power supply stability within the 4.75V to 5.25V window for reliable operation.
Part Context
This part belongs to the 74FCT series of high-speed CMOS logic devices. It serves as a registered or unregistered bus transceiver depending on specific suffix variations. The manufacturer transitioned from Integrated Device Technology (IDT) to Renesas Electronics Corporation, maintaining product lineage under the new branding.
Replacement Considerations
Public confirmed substitute part numbers include CY74FCT2543ATQCT, CY74FCT2543CTQCT, CY74FCT543ATQCT, and CY74FCT543TQCT from Texas Instruments. Verify pin compatibility and electrical specifications before substitution.
