CD4010BM - Hex Non-Inverting Buffer | Texas Instruments
Teilenummer: CD4010BM ✓ AktivCD4010BM Übersicht
A CMOS logic buffer is an interface device that reproduces a binary input signal at its output without changing its logic polarity. In the signal-processing hierarchy, this six-channel device belongs to the CMOS logic family and the broader category of buffers and logic-level converters. The non-inverting configuration preserves high and low logic states, making the CD4010BM useful for signal buffering, distribution, and CMOS-to-TTL or DTL interface applications.
The six independent channels provide flexible implementation of parallel data paths, control-signal isolation, fanout distribution, and logic conversion. Push-pull outputs are suitable for driving CMOS loads and support reliable operation at both logic levels. Operation is supported at 5 V, 10 V, and 15 V parametric ratings, while the verified 18 V input-current data indicates a maximum supply operating point of 18 V. The specified low input current helps minimize loading on the driving circuit.
The CD4010B family was designed around CMOS operating principles and provides independent non-inverting channels rather than a shared multiplexed data bus. This architecture avoids the bus-sharing restrictions of multiplexers and allows every input and output to be used simultaneously. The manufacturer documentation specifically identifies the CD4010B family for use as CMOS-to-TTL or DTL logic-level converters and as CMOS high-sink-current drivers.
Typical applications include buffering multiple digital control lines, translating slow or lightly loaded CMOS signals into more capable logic-driver outputs, distributing clock or gate signals, and supporting industrial or embedded systems that mix CMOS and legacy TTL or DTL interfaces. Six channels in one 16-pin package also reduce board area compared with six discrete single-channel buffers. Because the outputs are non-inverting, the part is preferable where polarity must remain unchanged.
Designers should verify input and output voltage levels against the load technology rather than assuming every TTL interface is guaranteed at every supply condition. Unused input pins must not float, and unused outputs should be left unconnected unless required by a specific test configuration. The 16-pin SOIC package also requires adequate lead spacing and soldering time appropriate for a 1.27 mm-pitch surface-mount footprint.
This page consolidates the verified manufacturer and distributor information, identifies the supported voltage and temperature qualifications, clarifies the limitations of drop-in replacement data, and provides practical interface-selection guidance beyond the basic catalog description.

Typische Anwendungen
CD4010BM ist geeignet für 6 Anwendungs: CMOS-to-TTL Logic Interface, Industrial Control Signal Distribution, Clock and Gate Signal Buffering, Embedded Data-Signal Conditioning, Legacy DTL Interface Support, Digital Control-Line Isolation.
CMOS-to-TTL Logic Interface
The CD4010BM is suitable for interface and signal-conditioning stages that connect CMOS circuitry to TTL or DTL inputs because its six channels preserve logic polarity and provide push-pull outputs. According to the Texas Instruments documentation, the CD4010B family may be used as a CMOS-to-TTL or DTL logic-level converter. Each channel can support a separate control or data signal, reducing discrete buffer count. The design must still verify the CD4010BM output levels against the receiver’s input thresholds, noise margins, supply voltage, and operating temperature; merely matching voltage families does not guarantee every threshold condition. The low maximum input current of 1 µA at 18 V also helps minimize loading on the source circuit.

Industrial Control Signal Distribution
The CD4010BM can distribute related digital control signals in industrial control equipment while keeping the source and destination logic states unchanged. Its six independent non-inverting channels allow one package to buffer enable, reset, select, or interlock signals without sharing a multiplexed bus. The verified -55°C to 125°C operating range is useful where temperature conditions exceed typical commercial expectations, although system qualification remains necessary. Designers should account for the push-pull output architecture, confirm adequate drive current for the connected loads, and use the low-input-current characteristics to avoid burdening the controller. The 16-pin SOIC package supports conventional surface-mount assembly while conserving board area.
Empfohlen
Clock and Gate Signal Buffering
The CD4010BM is appropriate for buffering clock, latch-enable, and gate-control signals when multiple CMOS destinations require a non-inverting interface. Its six independent channels prevent one buffer from imposing a shared enable or routing restriction, and the push-pull outputs provide a defined driven state suitable for normal CMOS logic. The manufacturer identifies the family as usable for CMOS high-sink-current drivers, making it relevant to selected legacy-interface loads. Timing checks must include propagation delay and transition behavior from the controlled datasheet. Because the verified data does not provide explicit rise-time or fanout values, engineers should not infer guaranteed fanout from the six-channel organization alone.
Empfohlen
Embedded Data-Signal Conditioning
The CD4010BM can condition low-loading digital data paths in embedded systems that require several inputs to reach downstream logic without inversion. Its six 1-bit channels provide parallel buffering for data, address, or control lines, and the 16-pin SOIC package can reduce routing complexity compared with multiple discrete buffers. The maximum input current of 1 µA at 18 V over the full package-temperature range is the key verified electrical advantage when preserving source drive margin. Integration still requires checking supply compatibility and output drive against the receiving devices. If the design specifically requires inverting logic, an inverter buffer would be more appropriate, but it would not preserve the CD4010BM’s polarity.
Empfohlen
Legacy DTL Interface Support
The CD4010BM supports legacy DTL interface designs where a modern CMOS control circuit must drive older logic inputs without changing signal polarity. Texas Instruments explicitly describes the CD4010B types as usable as CMOS-to-TTL or DTL logic-level converters. Six channels make the device practical when a system needs several buffered command or acknowledgment lines rather than a single isolated signal. Compatibility must be established using the actual receiver thresholds, noise margins, timing requirements, and supply arrangement; a nominal CMOS-to-DTL use case does not remove those checks. The low typical input current of 100 nA at 18 V and 25°C helps preserve upstream drive capacity, while the wide -55°C to 125°C range supports harsh temperature ranges.
Empfohlen
Digital Control-Line Isolation
The CD4010BM can isolate digital control paths in mixed-signal or multi-section equipment because each non-inverting channel buffers its associated signal independently. This arrangement can reduce the loading seen by a sensitive source and provide push-pull drive to a following CMOS load. The maximum input current of 1 µA at 18 V across the full package-temperature range provides a concrete loading advantage, although the actual benefit depends on the source impedance and operating frequency. Engineers should validate that the output transition times and propagation delay meet the control-system timing budget, and should tie every unused input to a defined logic level. The SOIC package also makes the device convenient for repair and legacy-system modernization boards.

Designhinweise
Treat every connected input as a defined logic node. An unused CMOS input must be tied to VSS or VDD rather than left floating, because floating nodes can oscillate and create unpredictable transitions in adjacent circuitry. Keep the six buffered signals on controlled-impedance paths when they operate at high edge rates, and avoid long stubs or unnecessary test pads near the inputs. Verify propagation delay and output transition timing from the controlled manufacturer datasheet before relying on the device for high-speed clock distribution.
Place the supply bypass capacitor as close as practical to the VDD and VSS pins, and provide a low-impedance ground return. The manufacturer specifies 100% quiescent-current testing at 20 V, but the verified operating range extends to 18 V, so system rails must not exceed the applicable device limit. Account for supply-current changes and CMOS dynamic current when several of the six push-pull outputs switch simultaneously. Decoupling requirements and capacitor values should follow the controlled TI application guidance.
Do not substitute an inverting buffer for CD4010BM without changing the system logic, and do not assume every similarly packaged hex buffer has the same pin arrangement. The supplied family guidance specifically identifies CD4050B as the preferred CD4010B replacement except in multiplexer applications, demonstrating why functional equivalence and pin equivalence must be checked separately. For CD4010BMTG4, compare the controlled pinout, temperature grade, timing, output drive, and supply limits before approving it as a drop-in production substitute.
Use a standard 16-pin SOIC land pattern and observe the manufacturer’s soldering and board-assembly recommendations. Route each input directly toward its corresponding buffer pin and keep the ground plane continuous beneath and around the device where practical. Because all six channels share the same package supply system, keep high-current return paths away from sensitive input traces. Confirm pin 1 orientation on the PCB artwork, especially during conversion from a through-hole or different logic-buffer footprint.
Compliance-Informationen
The supplied verified results do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. The CD4010BM is a commercial 16-pin SOIC logic IC, not an explicitly identified AEC-Q100 automotive part.
