Overview
The 54FCT240TDB is a dual four-bit buffer and line driver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.5V to 5.5V and features three-state outputs. The device provides high drive capability with output currents of 12mA for high-level and 48mA for low-level states. Designed for through-hole mounting, it utilizes a 20-CDIP package with a pin pitch of 7.62mm. The component supports an extended operating temperature range from -55°C to +125°C.
Feature Summary
- Dual four-bit configuration providing independent buffering channels
- Three-state output capability for bus-oriented applications
- High current drive strength supporting direct interface loads
Applications
- Bus-oriented memory and address drivers
- Clock distribution and buffering circuits
- High-speed data transmission line driving
Procurement Notes
Verify the specific suffix 'TDB' against official Renesas documentation to confirm the exact package type and lead finish specifications. Confirm RoHS compliance status as military-grade variants often differ from commercial standards. Check for active production status or obsolescence notices prior to design finalization.
Selection Notes
Select this component when high-drive capability and three-state isolation are required for bidirectional bus architectures. Ensure the system voltage remains strictly within the 4.5V to 5.5V operational limits. Verify that the through-hole CDIP package dimensions fit the target PCB layout constraints.
Part Context
This part belongs to the 54FCT logic family, which combines FET transistor characteristics with CMOS technology for high-speed performance. The 54-series designation typically indicates military-grade temperature ranges and reliability standards compared to standard commercial 74-series counterparts.
Replacement Considerations
Consult official substitution guides for equivalent parts such as IDT54FCT240ATDB. Verify pin compatibility and electrical parameter alignment before replacing.
