MC14511BCPG

Display Drivers Overview

The MC14511BCPG is a BCD-to-seven segment latch/decoder/driver manufactured by onsemi. It utilizes complementary MOS (CMOS) enhancement mode devices for logic functions and NPN bipolar output drivers for high current capability. The device operates within a supply voltage range of 3 V to 18 V and supports a maximum input frequency of 3 MHz. It features a 14-pin PDIP package with through-hole mounting, suitable for industrial temperatures ranging from -55 °C to +125 °C. Static current is limited to 0.02 mA, with output currents up to 19.3 mA low and -16.3 mA high.

Display Drivers Feature Summary

• Integrates BCD latching, decoding, and seven-segment driving in a single CMOS-Bipolar hybrid structure
• Provides high-current NPN bipolar outputs capable of directly driving LED displays without external buffers
• Includes a lamp test input for verifying display segment functionality and a blanking input for suppressing outputs

Display Drivers Applications

• Direct drive interfaces for seven-segment LED numeric displays
• Industrial control panels requiring robust display drivers in wide temperature environments
• Consumer electronics utilizing LCD or vacuum fluorescent displays compatible with BCD inputs

Display Drivers Procurement Notes

Verify the specific suffix 'CPG' confirms the 14-pin PDIP package and lead-free compliance when ordering. Confirm that the application circuit matches the 3 V to 18 V supply requirements and that load conditions do not exceed the specified output current limits. Ensure ESD precautions are observed during handling as per standard CMOS component guidelines.

Display Drivers Selection Notes

Select this component when a combined latch, decoder, and driver solution is required for seven-segment displays. It is appropriate for designs needing direct LED drive capability with minimal external components. Consider the PDIP package for prototyping or applications requiring through-hole assembly. Verify that the input signal timing meets the specified propagation delay constraints at the operating voltage.

Display Drivers Part Context

This part belongs to the MC14511B family of BCD-to-seven segment decoders. It is functionally similar to other industry-standard equivalents but offers specific performance characteristics defined by onsemi's manufacturing process. The device is distinct from timer ICs like the MC14541, serving purely as a display interface component rather than a timing generator.

Display Drivers Replacement Considerations

Compatible substitutes include the MC14511BDWR and MC14511BCP. Verify pinout compatibility and electrical specifications before substitution. Ensure that any replacement part maintains the same output current capabilities and supply voltage range for the intended application.
