Description

54LS148J is an IC (Integrated Circuit) chip used for priority encoding of the inputs where only the highest order data line is encoded. It provides an efficient way of encoding data, avoiding the need for external circuitry to perform the encoding.

Specifications and features

• Product Category: IC Chips
• Number of data lines: 10 input lines
• Number of output lines: 4 (for 54LS147) and 3 (for 54LS148)
• Encoding Type: Priority Encoding
• Active Logic Level: Low
• Implied Decimal Zero Condition: Provided
• Cascading Circuitry: Available (Enable Input EI and Enable Output EO)

Application Scenarios

The 54LS148J IC chip is primarily used in digital circuits where priority encoding is required. Some of its applications include signal processing, data encoding, time multiplexing, and parallel-to-serial conversion. It also finds its use in communication systems and memory addressing.

Comparison

• Efficient priority encoding
• Easy to integrate with digital circuits
• Octal expansion allowed without external circuitry (for 54LS148)
• Implied Decimal Zero Condition available (for 54LS147)

• Low active logic level, not suitable for systems using high active logic level
• Requires a good understanding of digital circuitry for proper use
• Not suitable for analog circuits
