CD4541BFX

Overview

The CD4541BFX is a CMOS programmable timer manufactured by Harris Corporation, belonging to the 4000/14000/40000 series. It functions as a high-voltage type device with a 20V rating and operates within a supply voltage range of 3V to 18V. The component features a 14-pin DIP package and supports through-hole mounting. It includes an internal oscillator circuit controlled by external resistors and capacitors, allowing for frequency division ratios selectable via address pins. The device is designed for industrial applications, supporting an operating temperature range from -55°C to 125°C.

• Internal Oscillator Circuit with External RC Control
• Selectable Frequency Division Ratios: 1, 10, 256, or 65536
• Operating Supply Voltage Range: 3V to 18V

Applications

• Frequency Divider Circuits
• Programmable Timing Intervals
• Industrial Control Systems

Part Context

The CD4541BFX is part of the CD4541 family of CMOS programmable timers. The 'BF' suffix indicates a ceramic dual in-line package (CDIP), while 'X' typically denotes specific packaging or tape-and-reel configurations in some manufacturer lineups. This component is functionally equivalent to other variants like the CD4541BE but differs in physical packaging and handling specifications.

Replacement Considerations

Compatible replacements include the CD4541BE and CD4541B from Texas Instruments or Harris Corporation. Verify that the substitute component matches the required package type (DIP vs. CDIP) and voltage ratings. Ensure the replacement supports the same frequency division options and operating temperature range.
