CD74HC4511M96 概要
A BCD-to-7-segment decoder is a logic IC that converts a 4-bit Binary Coded Decimal input (0-9) into the seven individual segment drive signals (a, b, c, d, e, f, g) needed to display a decimal digit on a 7-segment LED or LCD display. These devices sit in the logic IC hierarchy: decoder/driver -> display driver -> logic IC -> integrated circuit -> semiconductor. They are essential building blocks in numeric displays used in instrumentation, appliance panels, industrial counters, and embedded systems where a microcontroller must drive multi-digit readouts efficiently.
Key features of the CD74HC4511M96 include input latches for BCD code storage, allowing data to be held stable while multiplexing multiple digits; lamp-test and blanking capability for testing all segments simultaneously and for PWM-based dimming; balanced propagation delays and transition times; and significant power reduction versus the original CD4000-series CMOS designs. The high-output sourcing capability (10 mA at 6 V) eliminates the need for external segment drivers in most LED display applications.
The CD74HC4511M96 uses CMOS technology with CMOS-compatible inputs on the HC variant. Its 16-pin SOIC (D) small-outline surface-mount package measures approximately 9.9 mm x 3.9 mm with a 1.27 mm pin pitch, making it well-suited to compact PCB layouts. The integrated latch enables display multiplexing with no external storage, simplifying firmware and reducing microcontroller pin count when several digits share a data bus.
Typical applications include digital panel meters, instrument counters, industrial control readouts, appliance displays (microwave ovens, washing machines), electronic scoreboards, point-of-sale terminals, and any embedded system that needs to display decimal digits on a 7-segment LED or LCD. Designers use it when they need a hardware decoder to offload display refresh from a microcontroller or when supporting multi-digit multiplexing without continuous MCU intervention.
When designing with this device, add series resistors between each segment output and the LED anodes to limit current, or use a constant-current driver if brightness uniformity is critical. For multi-digit multiplexing, route BL through a PWM signal or high-frequency oscillator to achieve dimming and ghosting reduction. The LE (Latch Enable) input must be low for transparent operation and high to store the BCD code. The 'M96' suffix indicates tape-and-reel packaging for high-volume assembly.

Digital Panel Meters
The CD74HC4511M96 is well-suited to digital panel meters because its BCD-to-7-segment decoding and integrated input latch simplify firmware on the host microcontroller. With 10 mA source current per segment at 6 V VCC, the device directly drives common-cathode LED displays sized 0.3" to 1.0" with external current-limiting resistors, eliminating the need for external segment drivers. The BL (active-low blanking) input enables leading-zero suppression and overrange indication by blanking unused digits during multiplexing. The 2-6 V wide VCC range supports both 3.3 V and 5 V microcontroller-based meter designs, and the -55 C to +125 C operating range covers industrial panel meter environments. The 16-pin SOIC (D) package fits compact meter PCBs behind the display.

Industrial Counters and Timers
In industrial event counters and elapsed-time displays, the CD74HC4511M96 reduces microcontroller pin count by handling all BCD-to-7-segment decoding in hardware. Four BCD lines per digit replace seven MCU-driven segment lines, freeing GPIO for sensor inputs, relay control, and communication. The integrated latch (LE) lets the MCU update multiple digits sequentially with stable displays between updates, eliminating flicker during refresh. The 10 mA per-segment source capability directly drives large industrial 7-segment displays used in factory-floor counters without external drivers. The -55 C to +125 C industrial temperature range ensures reliable operation in unconditioned factory environments, and the 16-pin SOIC supports dense PCB layouts behind front panels.

Appliance Displays
Microwave ovens, washing machines, and white goods benefit from the CD74HC4511M96's low power consumption and hardware BCD decoding, which simplifies main-board design and reduces EMI from software-driven segment updates. The 2-6 V VCC range supports direct interface with 3.3 V or 5 V appliance microcontrollers without level shifters. The lamp-test (LT) input enables factory self-test routines that light all segments on power-up for visual verification, while the BL input supports dimming via PWM. The 16-pin SOIC (D) surface-mount package suits automated high-volume appliance PCB assembly. The CMOS HC technology provides low quiescent current suitable for energy-conscious appliance designs.

Electronic Scoreboards and Point-of-Sale
Scoreboards and POS terminals use the CD74HC4511M96 to drive large multi-digit numeric readouts with hardware BCD decoding that offloads refresh logic from the main controller. The 10 mA per-segment output at 6 V drives medium-sized LED digits directly; for larger displays, external transistors can be added. The active-low blanking (BL) input allows individual digit blanking for scoreboard format switching, while the LE latch stabilizes displays during ball updates. The wide operating temperature range supports outdoor scoreboard installations. The 16-pin SOIC allows compact scoreboard controller PCB designs where multiple decoder chips serve each digit column.

The CMOS-compatible inputs interface directly with 3.3 V or 5 V measurement ASICs and microcontrollers without level translation. The lamp-test (LT) input enables bench self-test diagnostics, while the blanking (BL) input supports overrange and underrange indication by blanking leading digits. The -55 C to +125 C specification supports temperature-controlled laboratory environments and outdoor field instruments. The integrated latch eliminates segment flicker during MCU ADC updates and display refresh.
おすすめ
Embedded System Numeric Displays
Hobby electronics, Arduino/Raspberry Pi projects, and embedded development boards use the CD74HC4511M96 to add hardware-decoded 7-segment displays without burdening the host MCU with software-driven multiplexing. The four BCD inputs (D0-D3) connect directly to four GPIO pins, freeing the remaining MCU pins for sensors, communication, and user I/O. The 2-6 V VCC range supports both 3.3 V (Raspberry Pi, ESP32) and 5 V (Arduino) platforms. The integrated latch (LE) lets the MCU update BCD code at any time without flicker, while BL supports software-driven dimming.

設計ノート
The CD74HC4511M96 operates from 2 V to 6 V VCC for the HC version; for 5 V TTL systems, the CD74HCT4511M96 with TTL-compatible input thresholds is recommended to avoid input-level noise. Decouple VCC (pin 16) with a 0.1 uF ceramic capacitor placed within 5 mm of the supply pin to suppress switching noise. Total quiescent current is typically under 1 uA at room temperature per the TI datasheet, but dynamic current increases with segment switching frequency - estimate 50 uA/MHz of switching activity for budget calculation.
Route segment output traces (pins 9-15) directly to the LED display anodes through individual current-limiting resistors. Keep trace lengths short (under 50 mm) to minimize ringing on the CMOS outputs. Place the CD74HC4511M96 within 25 mm of the display connector to reduce EMI. For multi-digit multiplexing with shared segment lines, add 100 ohm series resistors on each segment output to limit fault current during digit-to-digit transitions. Ground plane should be continuous under the IC with via stitching at the exposed SOIC thermal pad area (if present on layout).
Do not apply voltages above 6 V to VCC on the HC version - this can damage the CMOS input structures. For common-ANODE LED displays, the CD74HC4511M96 will NOT work directly because its outputs source current; use the SN74LS47 (active-low open-collector sink) instead. The LE (Latch Enable) input must be tied LOW for transparent (real-time) BCD following, or driven HIGH to freeze the displayed digit. The LT input is active-LOW - driving LT high allows normal operation, driving it low forces all segments ON regardless of BCD input. Always check the BL input polarity: BL low blanks segments, BL high enables normal display.
Separate analog/digital grounds if mixing the CD74HC4511M96 with precision analog circuitry on the same PCB. For designs driving large LED displays (>50 mA total segment current per digit), use a separate digital VCC trace with its own decoupling rather than sharing the main logic supply. The 16-pin SOIC (D) package does not have an exposed thermal pad, so standard SOIC land pattern with 1.27 mm pin pitch applies. Place the device away from heat sources such as power transistors or voltage regulators.
