Counter Dividers datasheet and documents for SNJ54LS592FK
Counter Dividers Overview
The SNJ54LS592FK is an asynchronous positive edge-triggered 8-bit up binary counter from the Texas Instruments LS series. It features registered inputs and multiplexed I/O with a TCO output. The device operates in asynchronous mode and supports bidirectional data flow through its multiplexed pins. It is housed in a CQCC20 ceramic package, designed for high-reliability applications requiring hermetic sealing.
Counter Dividers Feature Summary
- Asynchronous positive edge-triggered 8-bit up binary counting functionality
- Multiplexed input/output configuration allowing shared pin usage for data and control
- Registered inputs to stabilize data before processing
- Hermetically sealed ceramic construction for environmental protection
Counter Dividers Applications
- Military aerospace systems requiring radiation-hardened or hermetic components
- Spacecraft telemetry and command data storage
- High-reliability industrial control counters
- Defense communication equipment timing circuits
Counter Dividers Procurement Notes
Verify the specific suffix FK indicates the CQCC20 ceramic leadless chip carrier package when sourcing. Confirm RoHS compliance status as military-grade variants often differ from commercial standards. Ensure the supplier provides traceability documentation for the hermetic seal integrity. Check for updated datasheet revisions that may affect pinout or electrical characteristics compared to older SN54LS592 versions.
Counter Dividers Selection Notes
Select this component when a hermetic ceramic package is mandatory for environmental durability. The multiplexed I/O feature reduces pin count requirements compared to dedicated input/output designs. Consider the asynchronous nature of the counter for applications where clock skew is not critical. Verify that the open-collector or specific output drive capabilities meet the load requirements of the downstream circuitry.
Counter Dividers Part Context
This part belongs to the SN54LS591/592 family of 8-bit binary counters. The SN54 series denotes military-grade specifications with extended temperature ranges and hermetic packaging options. The LS suffix indicates Low-power Schottky logic technology, offering a balance between speed and power consumption. The FK suffix specifically identifies the ceramic quad flatpack no-lead (CQCC) package variant.
Counter Dividers Replacement Considerations
SN54LS592FK is the commercial equivalent without hermetic sealing. SN74LS592D/N are plastic package alternatives for non-military use. SNJ54LS593J offers similar counting functions but with different output configurations. Verify pin compatibility before substituting with other LS series counters.
