What are the key features of CD74HC4511PWR?
- BCD-to-7-segment decoder with integrated input latch for stable display output without external flip-flops
- 7 segment outputs sinking up to 5.2 mA each, directly driving common-cathode LED displays at 5 V
- High-speed HC CMOS family with 2 V to 6 V supply range and propagation delay as low as 14 ns at 50 pF
What is CD74HC4511PWR used for?
CD74HC4511PWR is designed for direct interfacing between BCD data sources and 7-segment LED or LCD displays in digital meters, counters, and industrial panel readouts. Its on-chip latch allows stable digit display while BCD inputs change, making it ideal for multiplexed digit scan circuits. Consumer electronics, test instruments, and frequency counters with numeric readout benefit from its simple 4-wire BCD input to 7-output decode function.

Frequently Asked Questions
How much current can each segment output of CD74HC4511PWR sink when driving a common-cathode LED display?
Each segment output of CD74HC4511PWR can sink up to 5.2 mA when operating at a 5 V supply, which is sufficient to directly drive common-cathode 7-segment LED display segments with appropriate series resistors, eliminating the need for external current driver transistors in low-brightness applications.
Does CD74HC4511PWR include a latch function, and how is it used in multiplexed display systems?
CD74HC4511PWR integrates a 4-bit BCD input latch controlled by a dedicated LE (latch enable) pin. When LE is held high, the decoder output holds the last valid BCD digit regardless of input changes, enabling time-multiplexed display designs where the BCD bus is shared among multiple digit positions scanned at rates above 100 Hz.
For a 3.3 V microcontroller design driving CD74HC4511PWR, is the device compatible with that supply voltage?
CD74HC4511PWR operates from 2 V to 6 V supply, so it can run at 3.3 V. At 3.3 V the output sink current is reduced to approximately 2 mA, and propagation delay increases slightly compared to 5 V operation. Most common-cathode LED segments require only 1 mA to 2 mA for adequate brightness, so 3.3 V operation is feasible in many designs.
When is CD74HC4511PWR a better choice than a software-decoded GPIO approach for 7-segment display driving?
CD74HC4511PWR reduces the microcontroller I/O pin requirement from 7 segment pins to just 4 BCD pins plus 3 control pins, freeing up GPIO resources. In systems where the MCU is I/O-pin-constrained or where hardware decode offloads real-time scan processing, the CD74HC4511PWR saves firmware complexity and reduces CPU interrupt overhead compared to bit-banging 7 segment outputs directly.
