Overview
The IDT29FCT52ASO is an octal registered bus transceiver manufactured by Integrated Device Technology. It operates within a supply voltage range of 4.75 V to 5.25 V and supports bidirectional data transfer across eight independent channels. The device utilizes FAST CMOS technology, providing TTL-compatible inputs and outputs with high drive capabilities. It features power-off disable functionality to permit live insertion without system disruption. The component is housed in a 24-pin SOIC package and is designed for high-speed digital applications requiring registered data buffering.
Feature Summary
- Octal Registered Bus Transceiver
- Power-Off Disable Outputs
- High Drive Capability
- TTL Compatible I/O
Applications
- High-speed data bus buffering
- Live insertion systems
- Registered data transfer interfaces
Procurement Notes
Verify the manufacturer designation carefully, as Texas Instruments produces the CY29FCT52 series which shares similar specifications but carries a distinct part number prefix. Confirm the specific suffix 'SO' indicates the correct SOIC package variant required for your design. Ensure compliance with RoHS directives if lead-free components are mandatory for your assembly process.
Selection Notes
Select this component when an octal registered transceiver with power-off protection is required. It is suitable for designs needing high drive strength and TTL compatibility. Consider the QSOP or SSOP variants if space constraints exist, or the CT/DT grades for higher speed performance requirements compared to the ASO grade.
Part Context
This device belongs to the FCT (FAST CMOS) family of logic products from IDT. It serves as a registered version of standard bus transceivers, adding storage capability to maintain data integrity during transfers. The family includes various speed grades and packaging options to accommodate different system timing and physical layout needs.
Replacement Considerations
The Texas Instruments CY29FCT52AT/BT/CT series offers functional equivalents. Verify pinout compatibility and electrical characteristics before substitution. Other IDT variants like the 29FCT53 may serve as alternatives depending on specific speed or package requirements.
