MC14511BDWR2G is listed in the Display Drivers range at ChipApex. The manufacturer field lists onsemi. Its product description is IC LATCH/DECDR/DRVR 7SEG 16-SOIC. Review the specifications below when checking this part for your BOM.
The MC14511BDWR2G is a CMOS BCD-to-7-segment decoder/driver manufactured by onsemi. It accepts four-bit binary-coded decimal inputs and drives seven-segment displays. The device operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55 °C to +125 °C. It features latched inputs with a strobe function, high noise immunity, and standard SOIC-16 surface-mount packaging.
Verify the specific suffix 'BDWR2G' against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the SOIC-16 wide variant. Confirm RoHS compliance status through manufacturer declarations prior to integration into regulated assemblies.
Select this component when a dedicated decoder with input latching is required for static numeric displays. Compare against non-latching variants if real-time input tracking without storage is necessary. Verify that the output drive current meets the specific segment requirements of the target display unit.
This part belongs to the MC14511B family of logic integrated circuits. It serves as a complementary solution to other display drivers in the 4000/14000 series. The device provides a standardized interface between digital logic outputs and visual indication components in embedded systems.
MC14511BDW (non-RoHS version)
No, the datasheet does not specify internal pull-up resistors; external components may be required depending on the circuit design.
The blanking input forces all outputs low, effectively turning off the display regardless of the decoded state.
