74F537PC

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74F537PC is a 1-of-10 decoder/demultiplexer featuring four active HIGH BCD address inputs and ten mutually exclusive outputs. It includes a polarity control input to select active HIGH or LOW output states, alongside an Output Enable (OE) input for high impedance control. The device supports demultiplexing via two input enables (E1/E2). Operating at +4.5V to +5.5V, it delivers propagation delays up to 20.0ns max at 50pF load and operates within a 0°C to +70°C temperature range in a 20-Lead PDIP package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides one-of-ten decoding with mutually exclusive outputs controlled by four BCD address lines.
• Features configurable polarity control to switch between active HIGH and active LOW output states.
• Includes dual input enables for data demultiplexing in non-inverted or inverted forms.
• Offers three-state outputs with high impedance capability via the OE input.

Signal Switches, Multiplexers, Decoders Applications

• Demultiplexing data streams to selected outputs
• Decoding binary coded decimal signals
• Bus-oriented system interfacing

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify component authenticity as this part was originally manufactured by Fairchild Semiconductor prior to integration into onsemi. Confirm the specific ordering code matches the required package type, as tape and reel options exist with different suffixes. Check current availability status as legacy logic components may have limited stock or obsolescence risks.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single-channel 1-of-10 decoding function is required with flexible polarity and enable controls. Ensure the design accommodates the specified supply voltage range of 4.5V to 5.5V. Consider the 20-pin DIP footprint for through-hole implementations or SOIC for surface mount alternatives if pin compatibility allows.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the 74F series of high-speed logic components. It functions as a specialized decoder/demultiplexer hybrid, distinct from standard decoders by its additional demultiplexing capabilities via E1 and E2 inputs. The 74F series is characterized by faster switching speeds compared to standard TTL equivalents.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for equivalent parts from other manufacturers supporting the 74F logic family. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive current before substitution.
