54LS48J/B

Overview

The 54LS48J/B is a BCD-to-seven-segment decoder manufactured by Rochester Electronics. It operates within a voltage range of 4.5V to 5.5V and utilizes a 16-DIP package. The device functions as a single-element decoder/demultiplexer designed for driving seven-segment displays from Binary-Coded Decimal inputs.

Feature Summary

Converts four-bit binary-coded decimal inputs into seven-segment display signals
Includes internal pull-up resistors for segment drive capability
Features blanking input to suppress display output when inactive

Applications

Digital clock displays
Numeric readout panels
Industrial control instrumentation

Procurement Notes

Verify the component source documentation confirms the specific J/B suffix designation and package integrity. Ensure the datasheet matches the required logic family characteristics and pinout configuration for your circuit design before integration.

Selection Notes

Select this component when a dedicated BCD-to-seven-segment decoder with internal current limiting is required. It is suitable for applications needing direct interface between digital logic outputs and visual numeric indicators without external decoding logic.

Part Context

Rochester Electronics specializes in manufacturing legacy and obsolete semiconductor components. The 54LS48J/B represents a recreation of original designs, maintaining compatibility with standard TTL logic families while providing supply continuity for discontinued parts.

Replacement Considerations

Direct substitutes include SN54LS48 and SN74LS48 variants. Verify pin compatibility and electrical specifications against the original system requirements before substitution.
