Overview
The 54LS256DM is a 4-bit D-type latch integrated circuit manufactured by Rochester Electronics, LLC. It utilizes TTL logic technology and integrates two independent functions within a single chip. The device features four bits per function, designed for data storage applications in digital systems. It is housed in a Ceramic Dual In-line Package (CDIP) with 16 pins, suitable for high-reliability environments requiring robust packaging and stable performance characteristics.
Feature Summary
- Integrates two independent 4-bit D-latch functions on a single chip
- Utilizes standard TTL logic technology for reliable digital signal processing
- Features ceramic dual in-line package construction for enhanced durability
Applications
- Digital data storage circuits
- Parallel-to-serial data conversion interfaces
- High-reliability military or aerospace electronic systems
Procurement Notes
Verify the specific manufacturing lot and date code upon receipt to ensure compliance with project requirements. Confirm that the CDIP package condition meets visual inspection standards. Ensure compatibility with existing system voltage levels and interface protocols before final integration into the design.
Selection Notes
Select this component when a dual-channel 4-bit latch solution is required in a ruggedized ceramic package. It is appropriate for designs needing TTL-compatible inputs and outputs where space efficiency and functional density are prioritized over surface-mount options.
Part Context
Rochester Electronics specializes in sustaining legacy semiconductor components. The 54LS256DM represents their capability to manufacture or source critical logic devices that may no longer be produced by original equipment manufacturers, ensuring supply continuity for long-life applications.
Replacement Considerations
Direct substitutes include other 54LS256 variants from different manufacturers offering identical pinouts and electrical specifications. Verify package dimensions and thermal characteristics when considering alternative sources.
