CD4050BK - 18V CMOS Hex Buffer | Harris Corporation
Référence : CD4050BK ✓ ActifCD4050BK Présentation
A CMOS buffer is a digital logic device that reproduces its input signal at an output with added drive strength. The CD4050 belongs to the CD4000 CMOS logic family, which sits within the broader digital IC and logic IC hierarchy. Unlike open-collector buffers, these devices use push-pull outputs, allowing them to source and sink output current without requiring an external pull-up resistor.
The verified CD4050 family information identifies six non-inverting channels, one output bit per element, 3 V to 18 V operation, and an 18 V maximum supply rating. CMOS construction supports low static power relative to many older bipolar logic families. The buffered outputs are intended to improve signal integrity when driving downstream logic or interconnect, while the single-supply level-conversion capability can bridge compatible systems operating at different logic thresholds.
The CD4050B family is based on complementary MOS circuitry using N-channel and P-channel enhancement-mode transistors. Separate input and output behavior should be checked against the relevant datasheet before finalizing edge-rate, fan-out, and loading calculations. The supplied source set confirms the CD4050B family's three-rail logic-level-conversion function and 3 V to 18 V supply range, but it does not provide a complete timing table, output-current rating, or absolute maximum ratings for the Harris CD4050BK.
Typical uses include buffering digital control signals, interfacing compatible CMOS logic domains, clock distribution, and driving multiple standard CMOS loads. The non-inverting topology preserves signal polarity, while six independent channels make the device useful when more than one buffered logic path is required. Board-level applications should avoid using the CD4050BK for high-speed differential signals, high-voltage isolated interfaces, or loads exceeding the verified output-current capability.
A key design consideration is that buffered CMOS outputs still have finite rise and fall times. Long PCB traces, capacitive inputs, stacked supply pins, and high fan-out can slow edges and create timing-margin risk. Decoupling capacitors should be placed close to the supply pins, while unused inputs must be connected to a defined logic level. Exact capacitor values, drive-current limits, and timing thresholds require the missing manufacturer data.
This page consolidates the verified distributor identity, package description, CD4050B family supply range, logic function, cross-reference results, and practical design constraints. It also distinguishes verified facts from unavailable electrical details rather than estimating pinout, timing, thermal, or lifecycle values that are not present in the supplied sources.

Applications typiques
CD4050BK convient pour 6 applications: CMOS Logic Signal Buffering, Single-Supply Logic-Level Conversion, Clock and Control-Line Distribution, Industrial Control Signal Conditioning, Legacy Digital System Interfacing, Low-Power CMOS Signal Routing.
CMOS Logic Signal Buffering
The CD4050BK fits applications requiring six independent, non-inverting buffered logic paths because each channel provides one bit with a push-pull output. According to the verified DigiKey listing, the device contains six one-bit elements in a 16-CFP package. It can reduce sensitivity to moderate capacitive loading when driving another compatible CMOS input. The trade-off is that the supplied evidence does not include propagation-delay or output-current curves, so timing margin and fan-out must be checked against the exact datasheet.
Recommandé
Single-Supply Logic-Level Conversion
The CD4050BK supports compatible CMOS logic-level conversion using one supply voltage, as stated in the verified CD4050 family documentation. Its six non-inverting channels allow multiple signal domains to be buffered without inversion. With a verified family supply range of 3 V to 18 V, the device is relevant to mixed-voltage CMOS interfacing. Engineers must ensure that input and output thresholds remain valid at the selected VDD because detailed threshold values were not included in the supplied sources.
Recommandé
Clock and Control-Line Distribution
Six buffered channels make the CD4050BK suitable for distributing a clock or several control signals among compatible CMOS loads. The push-pull topology can source and sink current without a pull-up resistor, which differs from open-collector implementations. Its non-inverting behavior preserves clock polarity at each channel. However, edge-rate degradation, channel-to-channel skew, and maximum fan-out are not quantified in the verified data, making PCB trace length and load analysis essential before use.
Recommandé
Industrial Control Signal Conditioning
The CD4050BK can condition compatible digital control signals in industrial equipment while preserving logic polarity. The verified 3 V to 18 V CD4050B-family supply range allows deployment across multiple common logic environments, subject to the selected interface thresholds. Its ceramic flat-pack construction may suit legacy or high-reliability assemblies where the 16-CFP footprint is already qualified. Designers still need to verify environmental ratings, propagation delay, noise margin, and output loading from the exact Harris datasheet.
Recommandé
Legacy Digital System Interfacing
CD4050BK is relevant when maintaining or replicating a legacy design that uses the Harris 16-CFP footprint. Its six non-inverting CMOS channels can buffer digital paths while retaining single-supply level-conversion capability. Compatibility with the target board depends on exact pin mapping, supply polarity, and signal thresholds, none of which are fully present in the supplied snippets. A schematic and package drawing should therefore be checked before treating another CD4050-family device as interchangeable.
Recommandé
Low-Power CMOS Signal Routing
The CD4050BK uses complementary MOS circuitry and can route low-level compatible digital signals without inversion. The verified family description identifies N-channel and P-channel enhancement-mode transistors, while the source set confirms single-supply logic-level conversion. This topology is useful when a design requires buffered CMOS signals rather than mechanical relay contacts or bipolar logic. Exact static-current and dynamic-power figures were not provided, so total power cannot be quantified without the missing electrical tables.

Notes de conception
Do not treat every CD4050B-family ordering code as a mechanical replacement for CD4050BK. The verified Harris CD4050BK listing specifies 16-CFP, while the verified TI CD4050BE listing specifies 16-PDIP. Confirm the package drawing, pin numbering, supply connections, and signal assignments before using a related part; a shared logic function does not establish pin-to-pin or same-footprint compatibility.
Keep the supply connection and local bypass capacitor close to the device on the PCB. The supplied data verifies 3 V to 18 V CD4050B-family operation but does not provide recommended capacitance, ESR, or layout values. Use the exact manufacturer datasheet for those requirements and avoid allowing supply transients or ringing to exceed the verified 18 V maximum supply rating.
The CD4050BK provides buffered CMOS outputs, but finite rise and fall times still limit usable bandwidth and fan-out. Estimate the total capacitive load, include receiver input capacitance, and preserve timing margin for the longest trace. The supplied data does not provide output-current, propagation-delay, or capacitive-load curves, so a conservative load limit should be established from the exact Harris datasheet rather than estimated from the logic family.
Place each input and output connection so that high-current switching loops remain away from sensitive logic nodes, and route the device's supply path with low inductance. Although exact pin names are not included in the verified snippets, the 16-CFP footprint should be compared against the manufacturer drawing before drilling or soldering. Verify assembly compatibility, ceramic-package fragility, and manufacturer-recommended soldering process data before production.
