Product details
Overview
74HCT4511D,652 from Nexperia is a TTL-level-compatible BCD-to-7-segment latch/decoder/driver in SO16 package, featuring active-low latch enable (LE), lamp test (LT), and ripple blanking (BI) inputs, 10 mA per-output drive capability, and operation from 4.5 V to 5.5 V across –40 °C to +125 °C. It directly drives common-cathode LED displays in digital instrumentation and industrial panel meters.
For engineers reviewing the 74HCT4511D,652 datasheet, 74HCT4511D,652 pinout, 74HCT4511D,652 application, or 74HCT4511D,652 equivalent, key selection criteria include TTL input compatibility, latch-controlled static segment output stability, ripple blanking for leading-zero suppression, and guaranteed 10 mA sink current per segment at 5 V.
Technical Context
The device integrates four independent D-type latches followed by a BCD-to-7-segment decoder and seven high-current output drivers. Latch storage isolates segment outputs from input bus transitions, enabling stable display updates synchronized to LE edge.
LT forces all segment outputs HIGH (illuminating all segments); BI forces all outputs LOW (blanking entire display). Both LT and BI operate asynchronously and bypass the latch, allowing immediate visual control independent of BCD data state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures direct compatibility with 5 V TTL logic systems without level shifting. |
| Input Logic Level | TTL - Accepts standard 5 V TTL thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), eliminating need for external interface buffers. |
| Output Drive | 10 mA sink per segment (a–g) at VO = 0.4 V - Directly drives common-cathode LEDs with series resistors ≥ 330 Ω at 5 V. |
| Propagation Delay | 27 ns (typ) from LE to segment output - Enables reliable update timing in multiplexed displays up to ~10 kHz refresh rate. |
| Operating Temperature | –40 °C to +125 °C - Qualified for industrial control panels and automotive under-hood instrumentation interfaces. |
| Latch Enable Polarity | Active LOW - Synchronizes display updates on falling edge of LE, simplifying microcontroller GPIO control. |
| Blanking Input | Ripple blanking (BI) active LOW - Supports cascaded blanking for multi-digit displays to suppress leading zeros automatically. |
Pinout & Package
74HCT4511D,652 uses the SO16 (SOT109-1) plastic small outline package: 16-pin, 3.9 mm body width, 1.27 mm lead pitch, surface-mount compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B (BCD input) | Second least-significant BCD bit; sampled only when LE is LOW or during LE transition. |
| 2 | C (BCD input) | Third least-significant BCD bit; part of 4-bit latch input stage feeding decoder. |
| 3 | LT (Lamp Test) | Asynchronous active-LOW input forcing all segment outputs HIGH - used for display continuity verification. |
| 4 | BI (Ripple Blanking Input) | Asynchronous active-LOW input forcing all segment outputs LOW - enables zero-suppression in multi-digit systems. |
| 5 | LE (Latch Enable) | Active-LOW control: latches current BCD inputs on HIGH-to-LOW transition; holds outputs stable thereafter. |
| 6 | D (BCD input) | Most-significant BCD bit; determines digit value 0–9 or blank when combined with A–C. |
| 7 | A (BCD input) | Least-significant BCD bit; forms complete 4-bit binary-coded decimal address for segment mapping. |
| 8 | GND | Ground reference for all logic and output stages; must be low-impedance for stable segment current sinking. |
| 9 | e (Segment output) | Drives segment 'e' of common-cathode 7-segment display; sinks up to 10 mA at 5 V supply. |
| 10 | d (Segment output) | Drives segment 'd'; electrically identical to other segment outputs with same drive strength and timing. |
| 11 | c (Segment output) | Drives segment 'c'; shares latch/decoder path and output driver architecture with a–g outputs. |
| 12 | b (Segment output) | Drives segment 'b'; output voltage swing is rail-to-rail (0 V to VCC) under no-load conditions. |
| 13 | a (Segment output) | Drives segment 'a'; output remains latched and stable even if A–D inputs change after LE goes HIGH. |
| 14 | g (Segment output) | Drives segment 'g'; supports blanking via BI regardless of latch state or BCD input. |
| 15 | f (Segment output) | Drives segment 'f'; output clamping diodes allow safe interfacing to voltages exceeding VCC. |
| 16 | VCC | Positive supply input; decoupling capacitor (100 nF) required near pin for noise immunity and transient current delivery. |
Key Features
| Feature | Design Value |
|---|---|
| Latch-controlled output stability | Outputs remain fixed after LE HIGH transition, enabling glitch-free display updates independent of BCD bus activity. |
| Asynchronous lamp test | LT input forces all segments ON instantly - critical for factory test and field diagnostics without software intervention. |
| Ripple blanking support | BI input allows daisy-chaining multiple 74HCT4511 devices to blank leading zeros in multi-digit numeric displays. |
| TTL-compatible inputs | Accepts standard 5 V TTL logic levels, eliminating level shifters in legacy 5 V microcontroller or FPGA designs. |
| Industrial temperature range | Specified from –40 °C to +125 °C - suitable for DIN-rail PLC modules and outdoor HMI enclosures without derating. |
Applications
| Digital Panel Meter Display | Industrial Programmable Logic Controller (PLC) HMI |

Equivalent & Alternatives
The following parts are listed as comparable options for similar BCD-to-7-segment latch/decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC4511D,652 | CMOS input thresholds (VIH ≥ 3.15 V @ 4.5 V); wider 2–6 V supply range | Suitable for mixed-voltage systems (e.g., 3.3 V MCU with 5 V display rail) but requires level translation from TTL sources | Select when system uses CMOS logic families or variable supply rails; not drop-in for TTL-only designs. |
| CD4511BE | Single-supply 3–18 V operation; higher propagation delay (~100 ns); no ripple blanking input | Lacks BI pin - cannot support leading-zero suppression in multi-digit displays without external logic | Choose for ultra-wide voltage applications where timing and blanking features are secondary; verify segment drive strength at target VCC. |
Compared with 74HC4511D,652 and CD4511BE, the 74HCT4511D,652 uniquely combines TTL input compatibility, ripple blanking, and 10 mA segment drive in a single industrial-grade SO16 package - making it optimal for robust 5 V embedded display interfaces requiring minimal external components.

FAQ
Can 74HCT4511D,652 drive common-anode LED displays?
No - the 74HCT4511D,652 provides active-low (sink) outputs designed exclusively for common-cathode LED configurations. Driving common-anode displays would require external high-side drivers or logic inversion, which is not supported by the device's architecture or specified output characteristics.
What happens to segment outputs when LE is HIGH and BCD inputs change?
When LE is HIGH, the internal latches retain the last valid BCD value present at the moment LE transitioned HIGH. Subsequent changes to A–D inputs have no effect on segment outputs (a–g), ensuring display stability during bus contention or microcontroller reconfiguration.
Is ripple blanking (BI) functional when LE is HIGH?
Yes - BI operates asynchronously and independently of the latch state. When BI is pulled LOW, all segment outputs go LOW immediately, regardless of whether LE is HIGH or LOW, enabling real-time blanking without disrupting latched BCD data.
Does the device support LCD display driving?
No - the 74HCT4511D,652 is specified only for LED segment driving. Its DC output structure and lack of AC excitation capability make it unsuitable for LCDs, which require alternating voltage waveforms to prevent electrode degradation; Fig. 14 in the datasheet explicitly warns against direct DC drive of LCDs.
