Overview
The SNJ54ALS653W is an octal bus transceiver and register featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output levels. The device provides a propagation delay of 64 ns, with low-level output current of 24 mA and high-level output current of -15 mA. It is housed in a CFP-24 package and functions as an inverting logic circuit.
Feature Summary
- Integrates octal bus transceiver functionality with internal register capability for data storage.
Applications
- High-speed data transfer systems requiring registered bus interfaces.
Procurement Notes
Verify the specific suffix 'W' corresponds to the ceramic flatpack (CFP) package variant when sourcing. Confirm that the component meets military-grade specifications if required by the design, as indicated by the 'SNJ' prefix. Ensure compatibility with existing TTL logic levels and power supply constraints during integration.
Selection Notes
Select this component for applications requiring robust signal buffering and temporary data storage on an eight-bit bus. The ALS series offers a balance of speed and power consumption suitable for complex digital systems. Consider the physical package constraints of the CFP-24 form factor during PCB layout planning.
Part Context
This part belongs to the SN54ALS653 family of octal bus transceivers and registers. The 'SNJ' designation typically indicates a military-grade version produced by Texas Instruments, while the 'W' suffix specifies the ceramic flatpack package type. It serves as a critical interface component in digital logic designs.
Replacement Considerations
Direct substitutes include other SN54ALS653 variants such as SN54ALS653FK or SN54ALS653JT, provided the package style matches the design requirements. Verify pinout compatibility before substitution.
