CD4050BE - 6-Channel CMOS Buffer | Texas Instruments
부품 번호: CD4050BE ✓ 활성CD4050BE 개요
A CMOS buffer is a digital logic device that reproduces its input signal at the output while providing buffering and, in this case, non-inverting logic-level conversion. Within the product hierarchy, the CD4050BE is a six-channel buffer, part of the CD4000 CMOS logic series and the broader logic IC category. Unlike an inverting buffer, each of its six channels preserves the input logic state.
The six-channel architecture allows one package to serve several independent signal paths. Push-pull outputs provide a defined output state and make the device suitable for driving downstream CMOS inputs. Logic-level conversion can bridge signals whose voltage levels differ when the input and output thresholds remain compatible with the selected supply voltage.
The CD4050B family uses a single positive supply, and the verified product information identifies a 3 V to 18 V operating range. This broad range supports integration across legacy 5 V systems and higher-voltage CMOS logic where the input and output signal levels are compatible with the device thresholds. Exact propagation delay, output-current, and input-threshold values were not included in the supplied verified data and therefore are not asserted here.
Typical uses include interfacing signals between different logic-voltage domains, buffering multiple digital control lines, and driving CMOS inputs from sources operating at a different logic level. The device can also provide multiple non-inverting channels in logic circuits where inversion would be undesirable. Because each channel is independent, unused channels should be tied to a defined logic state according to the manufacturer recommendations.
The main design consideration is ensuring that every connected signal remains within the input and output limits of the selected 3 V to 18 V supply. Designers should also account for unused inputs, supply decoupling, output loading, and the maximum transition rates verified in the manufacturer datasheet. The through-hole PDIP package is intended for conventional through-hole PCB assembly rather than surface-mount production.
This page consolidates the verified manufacturer and distributor information for CD4050BE, adds same-package cross-reference options, and provides practical guidance for logic-level conversion, unused inputs, decoupling, and component selection. It also distinguishes confirmed characteristics from parameters that require consultation of the manufacturer datasheet before design release.

일반적인 애플리케이션

CMOS Logic-Level Conversion
The CD4050BE is suitable for buffering digital signals between voltage domains that can be supported by one 3 V to 18 V supply. Its six non-inverting channels preserve logic polarity while the CMOS buffer function isolates the driving source from the receiving input. This is useful when a lower-voltage controller must communicate with a higher-voltage CMOS load. The designer must confirm that every high and low input meets the CD4050BE thresholds and that the translated output meets the load’s voltage limits. Because the device uses a single positive supply, level translation is not automatically suitable for arbitrary voltage pairs; the actual input and output levels must be checked against the manufacturer datasheet.
추천
Multi-Channel Digital Signal Buffering
The six independent channels in the CD4050BE can isolate multiple digital control or data paths without changing their logic polarity. This arrangement is useful in control systems where several inputs must be presented to downstream CMOS logic with reduced source loading. The push-pull output provides a defined output state, while the non-inverting architecture avoids introducing the inversion that could complicate active-high control signals. Designers should avoid exceeding the verified electrical limits and should use the manufacturer’s guidance for unused inputs. The 16-pin PDIP package also provides through-hole assembly, making the device practical for legacy control boards, prototypes, and industrial equipment that still uses plated-through-hole layouts.
추천
Legacy 5 V CMOS Interface Board
The CD4050BE fits legacy systems that use 5 V CMOS logic while also operating across the family’s verified 3 V to 18 V supply range. Its non-inverting buffer channels can isolate interface signals between controller boards and peripheral logic while retaining the original active-high or active-low meaning. The broad supply range does not by itself guarantee arbitrary level translation, so each signal must satisfy the device’s input thresholds and the receiving circuit must accept the resulting output voltage. Through-hole DIP-16 construction is particularly useful when updating or repairing older industrial, instrumentation, and control equipment without redesigning the board footprint.
추천
Industrial Control Signal Conditioning
The CD4050BE can condition multiple low-current digital control signals before they enter a downstream CMOS logic section. Six non-inverting channels allow active-high or active-low commands to retain their intended polarity while being buffered from the source. This can reduce loading interactions when a controller output must serve more than one compatible input path. The implementation must preserve a valid common ground and should account for signal rise and fall times, wiring capacitance, and downstream input requirements. Because propagation-delay and transition-rate values were not included in the supplied verified data, timing-critical loops should be reviewed against the Texas Instruments manufacturer datasheet before deployment.
추천
Test and Measurement Interface Logic
The six buffered channels of the CD4050BE are useful in test and measurement equipment that translates or isolates multiple CMOS control lines. For example, instrument-control signals from one logic section can drive front-panel or measurement circuitry without directly loading the source. The non-inverting behavior preserves command polarity, and the push-pull output provides a deterministic drive state for compatible CMOS loads. The 3 V to 18 V operating range supports experimentation across different supply levels, but threshold compatibility remains the decisive constraint. Breadboard and legacy test fixtures commonly favor the 16-pin PDIP package, although users must confirm pin orientation and obtain the exact pinout from the manufacturer datasheet.
추천
Embedded and Retrofit Logic Interfaces
The CD4050BE can support interface upgrades in embedded-control or retrofit projects where a modern controller must communicate with established CMOS logic. Six channels provide enough parallelism for several related control signals, while the non-inverting configuration simplifies adaptation of existing positive-logic commands. The broad 3 V to 18 V family supply range is helpful when consolidating interfaces built around different CMOS voltage levels, although each signal path must still be checked for threshold overlap. The PDIP package is well suited to legacy through-hole boards and hand-wired prototypes, but production designs should verify pin numbering, decoupling requirements, operating temperature, and qualification requirements from the applicable manufacturer documentation.

설계 노트
Confirm the actual supply voltage, input thresholds, and output limits against the Texas Instruments CD4050B datasheet before applying the device. The verified 3 V to 18 V range describes the supply capability, but it does not mean every signal can be translated between any two voltages within that interval. Place a suitable bypass capacitor close to VDD and VSS, observe the manufacturer’s grounding recommendations, and ensure connected signals never exceed the absolute maximum ratings.
Use the exact 16-pin PDIP pin numbering from the manufacturer datasheet when creating or repairing the footprint. The verified search results confirm the package and pin count but do not provide the individual pin names, so they should not be inferred from generic DIP conventions. Preserve the package orientation mark, avoid excessive heat during soldering, and verify that adjacent board traces do not conflict with the IC body or pins.
Do not treat CD4051BE as a drop-in replacement merely because both devices use a 16-pin DIP; CD4051BE has a different multiplexed-buffer function. Likewise, a candidate with the same package and channel count must still be checked for voltage range, propagation delay, input thresholds, output current, temperature grade, and qualification. Unused input pins should be connected according to the applicable manufacturer datasheet rather than left floating.
