Product details

Overview

HCF4511M013TR from STMicroelectronics is a BCD-to-7-segment latch/decoder/driver IC with CMOS input logic and bipolar transistor outputs, designed to directly drive common-cathode LED displays. It features 25mA high-output sourcing capability, lamp test (LT) and blanking (BL) inputs, latched BCD code storage, and blanking for invalid codes (>1001). It operates from 3V to 20V and supports industrial temperature range (–55°C to +125°C).

For engineers reviewing the HCF4511M013TR datasheet, HCF4511M013TR pinout, HCF4511M013TR application, or HCF4511M013TR equivalent, key selection considerations include its 7-segment output drive strength, latch enable timing, BL/LT control behavior, and compatibility with common-cathode display interfaces in legacy instrumentation and multiplexed digital readouts.

Technical Context

The HCF4511M013TR integrates CMOS logic for low-power BCD decoding and latching with discrete NPN bipolar output transistors capable of sourcing up to 25mA per segment. Its latch enable (LE/STROBE) input captures and holds BCD data independently of subsequent input changes, enabling stable display updates in multiplexed systems.

Blanking (BL) forces all segment outputs low regardless of input state, while Lamp Test (LT) overrides blanking and drives all segments high for visual verification. The device blanks outputs for BCD codes 1010–1111 (decimal 10–15), ensuring only valid digits 0–9 are displayed.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3 V to 20 V - supports wide-rail operation across 5V, 10V, and 15V logic systems without level-shifting.
Output Sourcing Current	25 mA max per segment - enables direct drive of standard common-cathode LEDs without external buffers.
Input Leakage Current	±100 nA max at VDD = 18 V - ensures minimal loading on upstream BCD sources in battery-powered or high-impedance circuits.
Propagation Delay (BL input)	125 ns typ. at VDD = 15 V - allows fast blanking response during high-speed multiplexing (e.g., >1 kHz refresh).
Quiescent Current	0.04 µA typ. at VDD = 5 V - delivers ultra-low static power for always-on display subsystems.
Operating Temperature	–55 °C to +125 °C - qualified for automotive under-hood, industrial control panels, and outdoor metering applications.
Logic Compatibility	JEDEC JESD13B compliant - guarantees interoperability with standard B-series CMOS logic families and predictable noise margins.

Pinout & Package

Package: 16-pin SOIC (Small Outline Integrated Circuit), body width 3.9 mm, pitch 1.27 mm, JEDEC MO-136 variant (SO-16).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 6, 7	BCD Inputs (A, B, C, D)	Active-high parallel binary-coded decimal inputs; LSB = A (pin 7), MSB = D (pin 6); latched on LE rising edge.
3	Lamp Test Input (LT)	Active-high override: forces all segment outputs high for display continuity check, independent of BL state.
4	Blanking Input (BL)	Active-low global disable: pulls all segment outputs low, overriding LT and decoded data.
5	Latch Enable / Strobe (LE)	Active-high edge-triggered latch: captures current BCD input on rising edge and holds until next strobe.
8	VSS	Negative supply reference (GND); must be connected to system ground for proper biasing of internal CMOS and bipolar stages.
16	VDD	Positive supply rail (3–20 V); powers both CMOS logic core and bipolar output transistors.
9–15, 10–15	Segment Outputs (a–g)	Active-high open-collector-equivalent outputs (NPN emitter-follower sourced); drive common-cathode displays directly.

Key Features

Feature	Design Value
Integrated Latch Function	Eliminates need for external D-latches when synchronizing BCD updates with display refresh cycles.
Dual Control Inputs (LT/BL)	Enables hardware-level display diagnostics (LT) and dynamic intensity control or power gating (BL) without microcontroller intervention.
Wide Supply Range (3–20 V)	Permits direct use in mixed-voltage systems-e.g., 5V logic control with 12V LED supply-reducing external regulation overhead.
Valid Code Blanking	Automatically suppresses segments for illegal BCD inputs (10–15), preventing erroneous glyphs like "E" or "F" on 7-segment displays.
Standardized Output Drive	Guaranteed 25mA sourcing with symmetrical VOH/VOL ensures consistent brightness across segments and predictable current limiting via series resistors.

Applications

Digital Panel Meters

Industrial Control Displays

Use Scenario: 4-digit voltage/current measurement display in DIN-rail mounted power analyzers.

IC Role / Device Role / Timing Role: Decodes microcontroller-sent BCD values into segment drive signals; latch holds digit data during multiplexed scanning.

Use Value: Eliminates software-driven GPIO toggling for each segment, reducing MCU firmware complexity and CPU load.

Use Scenario: Status indicator on PLC I/O modules showing module address or fault codes.

IC Role / Device Role / Timing Role: Receives static BCD from configuration DIP switches and drives local 7-segment ID display.

Use Value: Provides immediate human-readable identification without requiring active controller communication or display driver firmware.

Legacy Instrumentation

Multiplexed Digital Clocks

Use Scenario: Analog-to-digital converter front-end in vintage benchtop multimeters (e.g., Fluke 8000-series derivatives).

IC Role / Device Role / Timing Role: Converts successive BCD outputs from ADC's parallel interface into stable digit segments.

Use Value: Matches timing requirements of slow-scan analog instruments where propagation delay <1 µs is sufficient and latch stability prevents flicker.

Use Scenario: 4-digit time-of-day display using time-multiplexed digit scanning at ~200 Hz.

IC Role / Device Role / Timing Role: Drives one digit per scan cycle; BL input blanks other digits while LE latches active digit's BCD.

Use Value: Enables low-pin-count microcontroller interface (4 BCD lines + BL/LE/LT) instead of 28 individual segment lines.

Equivalent & Alternatives

The following parts are listed as comparable options for similar BCD-to-7-segment latch/decoder/driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4511BE	Same CMOS/bipolar architecture but rated only to 18 V max; lower output drive (20 mA typ.); no guaranteed 25 mA spec.	Not suitable for 20 V display rails or high-brightness LED loads requiring full 25 mA.	Select CD4511BE only if supply ≤18 V and segment current ≤20 mA is acceptable.
MC14495P	CMOS-only output stage (no bipolar transistors); requires external drivers for >5 mA loads; no lamp test input.	Cannot directly drive LEDs; needs buffer transistors or ULN2003; lacks hardware diagnostic capability.	Choose MC14495P only when driving low-current indicators (e.g., LCD backlights) and diagnostics are handled in firmware.

Compared with CD4511BE and MC14495P, HCF4511M013TR uniquely combines 20 V tolerance, guaranteed 25 mA sourcing, and integrated LT/BL controls-making it the only option for robust, self-contained, high-brightness 7-segment display interfaces in industrial environments.

FAQ

What is the maximum supply voltage for HCF4511M013TR?

The absolute maximum supply voltage is +22 V, but the recommended operating range is 3 V to 20 V. Operation at 20 V is fully characterized per datasheet specifications-including output drive, propagation delay, and quiescent current-and is commonly used to drive higher-brightness LEDs without external boost circuitry.

Can HCF4511M013TR drive common-anode displays?

No. HCF4511M013TR provides active-high, sourcing outputs designed exclusively for common-cathode 7-segment displays. Driving common-anode displays would require external inverters or PNP-based buffer stages, which negate the IC's integrated drive advantage and increase board area and cost.

How does the Latch Enable (LE) input function in practice?

LE is edge-triggered: a rising transition captures the current BCD input (A–D) and holds it in the internal latch, decoupling display output from subsequent input changes. This allows asynchronous BCD updates while maintaining stable digit rendering-essential for multiplexed displays or noisy control bus environments.

Is HCF4511M013TR still in active production?

STMicroelectronics has marked HCF4511B variants-including HCF4511M013TR-as obsolete in official documentation. However, Aetrix Electronics maintains verified, traceable inventory of original ST-manufactured units with full lot traceability and extended lifecycle support for legacy design continuity.
