MAX458CPL - 8x4 Video Crosspoint Switch | Maxim Integrated
部品番号: MAX458CPL ✗ 生産終了MAX458CPL 概要
A video crosspoint switch is a routing semiconductor used to direct video signals between multiple sources and destinations. In the broader hierarchy, the MAX458CPL belongs to the interface IC family and provides a configurable signal-routing function between video sources and downstream display, processing, or monitoring equipment. Its buffered outputs are intended to preserve signal integrity when signals are routed through the switching matrix.
The MAX458CPL is identified in manufacturer-related listings as the MAX458/MAX459 8x4 video crosspoint-switch family with buffers. The MAX458CPL ordering code specifies the commercial temperature grade and a 40-pin DIP package. The product is intended for through-hole PCB assembly rather than surface-mount reflow assembly. Its rectangular DIP outline provides a straightforward connection pattern for equipment with sufficient board space and a suitable through-hole footprint.
Typical uses include video surveillance systems, video walls, broadcast and professional video test equipment, monitor routing, and embedded video distribution platforms. The switching matrix allows a controller to select which of eight video inputs feeds one of four buffered outputs. Designers should account for the device's legacy through-hole package, required bypassing, signal routing, grounding, and any video-level or timing constraints defined in the manufacturer datasheet.
For a new design, the MAX458CPL is most appropriate when an existing 40-pin DIP footprint and an 8x4 buffered-video architecture are required. For compact or modern equipment, a surface-mount implementation may simplify board layout, but any functional substitute must be verified for pin compatibility, video bandwidth, output drive, supply requirements, control logic, and operating temperature before use.
This page summarizes the available product information, package characteristics, functional architecture, sourcing details, and engineering considerations for engineers evaluating the MAX458CPL. Use the manufacturer datasheet and its pin-description table to verify signal assignments, timing, electrical limits, decoupling, and board-layout requirements before releasing a production design.

主な用途
MAX458CPL の用途: 6 件s: Video Surveillance Routing, Video Wall Display Control, Professional Video Test Equipment, Broadcast and Studio Monitoring, Embedded Video Distribution, Industrial Video Inspection.
Video Surveillance Routing
The MAX458CPL fits centralized video-surveillance routing systems where eight camera or playback signals must feed four selected destinations. Its 8x4 crosspoint arrangement allows a controller to assign sources to monitors, recorders, or downstream processors without duplicating the entire input stage. The four buffered outputs support the routing matrix, while the 40-pin through-hole DIP provides a conventional assembly option for rugged or serviceable equipment. Confirm the required video bandwidth, output amplitude, synchronization behavior, and control timing against the manufacturer datasheet before selecting component values and trace impedance.
おすすめ
Video Wall Display Control
The MAX458CPL is suitable for video-wall control systems that distribute eight source images among four display outputs. The switching matrix provides a practical mechanism for selecting which camera, computer, or test pattern appears on each downstream display channel. Because the device uses a 40-pin DIP package, it favors equipment with through-hole construction, adequate spacing, and manual serviceability rather than compact display electronics. System integrators should validate video timing, signal integrity across the selected traces, and buffer stability using the electrical and timing sections of the manufacturer datasheet.
おすすめ
Professional Video Test Equipment
The MAX458CPL can be used in professional video test equipment to route multiple composite or baseband video sources to selected measurement and display paths. Eight inputs and four buffered outputs allow operators or automated test software to present different patterns without rewiring the equipment for every test. The commercial-grade MAX458CPL ordering code is appropriate for ordinary commercial environments, subject to the actual operating-temperature limits stated in the datasheet. Probe points should preserve source impedance, grounding, and return paths so routing does not obscure waveform or frequency-response measurements.
おすすめ
Broadcast and Studio Monitoring
The MAX458CPL supports broadcast and studio monitoring systems where several synchronized video feeds must be routed to confidence monitors, scopes, or downstream frame synchronizers. The four buffered outputs can reduce the loading burden associated with driving selected external video paths, while the eight input channels provide flexible source selection. The legacy DIP package makes it practical for modular broadcast racks assembled with through-hole boards and replaceable modules. Engineers must check the specific video standard, maximum frequency, channel-to-channel timing, and termination requirements before implementation.
おすすめ
Embedded Video Distribution
The MAX458CPL can support legacy embedded video distribution equipment that needs to distribute eight generated or captured video streams among four peripheral display paths. It is most appropriate where a 40-pin through-hole footprint, buffered routing outputs, and controlled source selection are preferred over highly integrated surface-mount decoders. The implementation should include correct bypass and power-routing practices and should account for the finite board area required around the rectangular DIP package. Validate signal losses and logic levels at the selected input and output nodes with representative cable and termination loads.
おすすめ
Industrial Video Inspection
The MAX458CPL is applicable to industrial inspection systems that route multiple camera outputs to monitors, vision processors, or recording equipment. The eight-input, four-output matrix supports flexible workstation layouts and reduces the number of external source-selection switches required by the system integrator. A commercial-grade through-hole implementation may also simplify maintenance in production facilities where modules are replaced rather than densely assembled. Operators should verify environmental requirements, since the manufacturer records identify the temperature grade as commercial but do not state the numerical operating range.

設計ノート
Design the board around the exact 40-pin through-hole footprint associated with the MAX458CPL ordering code. Preserve the package's pin-1 orientation, provide adequate body clearance for insertion and servicing, and route video traces away from high-current switching nodes. Because the indexed material does not identify every pin function, assign each net from the manufacturer pin-description table rather than from package position alone. This prevents connectivity errors during schematic capture and PCB layout.
Treat every routed video channel as a high-speed analog signal path. Use short traces, continuous reference planes, controlled return-current paths, and terminations matched to the source and load impedances. Avoid adding long stubs or sharing narrow return paths between channels. The MAX458/MAX459 family includes buffered outputs, but buffering does not remove the need to verify source impedance, cable loading, edge rate, crosstalk, and output-drive margin against the datasheet limits.
Follow the manufacturer's bypass and decoupling recommendations when constructing the power network. Place required capacitors at the device pins with short, low-inductance connections and keep supply routing isolated from sensitive video paths. The available product records do not state the supply voltage, capacitor values, or control-level thresholds, so these values must be taken directly from the datasheet before schematic release. Do not infer power-pin locations from the 40-pin count.
Do not treat MAX458CPL and MAX459CPL as automatically interchangeable merely because both use a 40-pin DIP family package. Compare the pin table, control truth table, supply limits, timing, and operating-temperature specifications before substitution. The target is a commercial-grade legacy device, so also confirm board area, sourcing continuity, and manual serviceability. A mechanically similar package does not by itself guarantee drop-in electrical compatibility.
コンプライアンス情報
The product records identify the MAX458CPL as a commercial-grade 40-pin DIP video crosspoint switch but do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status.
