CMOS BCD-to-7-Segment LED Latch Decoder Drivers 16-TSSOP -55 to 125 The CD4511BPWR is a CMOS BCD-to-7-segment latch decoder/driver IC from Texas Instruments designed to directly drive common-cathode 7-segment LED displays. It converts a 4-bit BCD (Binary-Coded Decimal) input into the appropriate 7-segment output signals for displaying decimal digits 0–9. The device integrates latch, decode, and display driver functions in a single package, making it suitable for digital clocks, counters, panel meters, calculators, and embedded display systems. Key Features CMOS BCD-to-7-segment latch decoder/driver Directly drives common-cathode LED displays High output source current capability up to 25 mA Built-in input latch for BCD data storage Lamp Test (LT) function for display testing Blanking Input (BI) for display blanking/intensity control Automatically blanks invalid BCD inputs (>1001) Wide operating supply voltage range: 3 V to 18 V Low static power consumption with high noise immunity Compatible with CMOS, NMOS, and TTL logic levels Available in TSSOP-16 package (BPWR variant) #commonpartslibrary #integratedcircuit #leddriver
