CD4511BPWG4

Display Drivers Overview

The CD4511BPWG4 is a BCD-to-7-segment decoder and driver manufactured by Texas Instruments, belonging to the 4500B CMOS logic series. It features a 16-pin TSSOP surface-mount package with 4 binary inputs and 7 segment outputs. The device 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. Key electrical specifications include a propagation delay of 420 ns and a maximum output current capability of 6.8 mA per segment.

Display Drivers Feature Summary

• Converts 4-bit Binary-Coded Decimal (BCD) input signals into decoded outputs suitable for driving 7-segment LED displays.
• Includes internal latch functionality to store the BCD data, maintaining the display state independent of input changes.
• Provides high-current drive capability directly to LED segments without requiring external buffer components.
• Features a blanking input that allows suppression of all segment outputs for display control purposes.

Display Drivers Applications

• Digital clock and timer displays using 7-segment LEDs
• Numeric readouts in industrial measurement instruments
• Control panel indicators in consumer electronic devices
• Status display modules in embedded systems

Display Drivers Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free construction as per Texas Instruments standards. Confirm the TSSOP-16 package dimensions match the target PCB footprint. Ensure the supply voltage applied does not exceed the absolute maximum rating of 18 V. Check for availability of the tape-and-reel packaging format if automated assembly is required.

Display Drivers Selection Notes

Select this component when a CMOS-compatible decoder with latch capability is needed for 7-segment LED interfacing. The wide voltage range suits both low-power and higher-voltage LED arrays. Consider the TSSOP-16 package for space-constrained surface-mount designs. Verify that the 6.8 mA output current meets the forward current requirements of the selected LED segments.

Display Drivers Part Context

This part belongs to the CD4500B family of CMOS logic devices, known for high noise immunity and low power consumption. The CD4511 variant specifically addresses the need for direct LED driving in numeric display applications. It serves as a standard interface between microcontroller BCD outputs and visual indicators in various electronic systems.

Display Drivers Replacement Considerations

The CD4511BPWR is the non-compliant version of this component. Other compatible parts in the 4500B series may offer similar functionality but require verification of pinout and electrical characteristics against the datasheet.
