CD4511BPW

Display Drivers Overview

The CD4511BPW is a BCD-to-7-segment decoder/driver manufactured by Texas Instruments, belonging to the 4500 series of CMOS logic. It accepts four binary-coded decimal inputs and drives seven output lines for display devices. The component operates within a supply voltage range of 3 V to 18 V and supports a wide operating temperature range from -55 °C to +125 °C. It features a propagation delay of 420 ns and is housed in a 16-pin TSSOP surface-mount package.

Display Drivers Feature Summary

• Converts 4-bit binary-coded decimal input signals into active-high outputs suitable for driving 7-segment LED displays.
• Includes an internal lamp test function that forces all segment outputs high when activated.
• Provides a blanking input capability that suppresses all segment outputs regardless of the BCD input state.

Display Drivers Applications

• Driving common-anode 7-segment LED numeric displays
• Digital readout systems requiring BCD decoding
• Instrumentation panels with numerical indicators

Display Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and tape/reel specifications. Ensure the selected variant matches the required lead time and packaging format for the intended production volume. Cross-reference the datasheet revision to confirm compliance with current environmental standards.

Display Drivers Selection Notes

Select this component for applications requiring standard BCD-to-7-segment decoding with low static power consumption. Consider the TSSOP-16 package for surface-mount assembly constraints. Evaluate the 420 ns propagation delay against system timing requirements and ensure the 3 V to 18 V supply range aligns with the design's power architecture.

Display Drivers Part Context

This device is part of the CD4500B family of CMOS logic circuits produced by Texas Instruments. It serves as a dedicated decoder within this series, complementing other logic functions such as inverters and timers. The component is designed for general-purpose digital logic applications where reliable BCD conversion is necessary.

Display Drivers Replacement Considerations

Compatible alternatives include the CD4511BE (DIP-16 package) and the CD4511BPWR (TSSOP-16 reel package). Verify pin compatibility and electrical characteristics before substitution.
