Overview
The IDT74FCT164245NBTPA is a dual 8-bit bus transceiver from the 74FCT logic family, housed in a 48-pin SSOP package. It features non-inverting TTL input and output levels with a supply voltage range of 2.7V to 3.6V or 4.5V to 5.5V. Key electrical parameters include a maximum propagation delay of 5ns at 50pF load, -32mA high-level output current, and 64mA low-level output current. The device operates within a temperature range of -40°C to +85°C.
Feature Summary
- Provides bidirectional data transmission between two buses using dual 8-bit configuration
- Supports direct interface with TTL logic devices through compatible input and output levels
- Enables flexible power supply operation for both 3.3V and 5V system architectures
Applications
- High-speed data bus interfaces in computing systems
- Memory buffer applications requiring fast switching speeds
- I/O port expansion in embedded controller designs
Procurement Notes
Verify the specific suffix 'NBTPA' against official IDT documentation to confirm pinout and electrical characteristics match your design requirements. Ensure the SSOP-48 package dimensions align with your PCB footprint. Confirm that the manufacturer source provides valid traceability for this Integrated Device Technology component.
Selection Notes
Select this component when a dual 8-bit transceiver with TTL compatibility is required for 3.3V or 5V systems. The 74FCT series offers faster switching than standard 74HC logic. Consider the 5ns propagation delay and drive strength specifications to ensure signal integrity for your specific bus length and load conditions.
Part Context
This part belongs to the IDT 74FCT (Fast CMOS) family, designed for high-speed digital applications. It serves as a bridge between microprocessors and peripheral devices. The 74FCT164245 variant specifically addresses needs for wide data paths with robust driving capabilities in industrial and commercial environments.
Replacement Considerations
Check for cross-manufacturer equivalents such as Texas Instruments FCT164245 variants. Verify pin compatibility and electrical specifications before substitution. Note that Renesas Electronics now produces IDT-branded components.
