料号： TMC57253DSB ✗ 停产TMC57253DSB 概述
A CCD driver is an interface IC positioned between an imaging sensor, timing controller, and analog readout chain. CCD drivers generate the clock, reset, and gate waveforms required to transfer and accumulate charge in a charge-coupled device. In the broader semiconductor hierarchy, the TMC57253DSB belongs to the interface-IC class rather than the image-sensor or analog-signal-processing classes. This distinction matters because the device does not itself capture an image; it conditions and drives the signals used by the CCD and its associated readout electronics.
The verified part description identifies a 5/0 driver configuration with TTL-compatible inputs and CCD-compatible outputs. Adjustable clock levels provide flexibility when matching the requirements of the connected CCD array. A high-speed clear function supports sensor reset operations, while the serial-gate midlevel feature supports correlated double sampling by establishing an appropriate reference level in the readout system. These functions target timing-sensitive CCD rather than general-purpose display or storage applications.
The TMC57253DSB is implemented as a CMOS interface IC operating from 5 V. Solid-state reliability is explicitly identified in the available technical description, avoiding the mechanical lifetime limitations associated with electromechanical relays or vacuum devices. The commercial temperature grade and surface-mount package make the device suitable for commercial imaging equipment when its electrical limits and timing characteristics are compatible with the selected CCD and system clocking requirements.
Typical uses include CCD-based imaging modules, industrial vision systems, scientific cameras, barcode and document scanners, surveillance cameras, and legacy CCD readout boards. In each case, the driver provides the electrical interface and timing waveforms needed to connect a CCD array to downstream sampling electronics. The 24-HSOP package supports conventional PCB assembly, while the 5 V supply operation is consistent with many mixed-signal imaging designs.
Designers should confirm the complete electrical and timing specification against the manufacturer datasheet before layout or production use. In particular, verify the output levels, clock-edge relationships, clear timing, input compatibility, decoupling requirements, and CCD-specific output limits. Do not infer unseen timing values or pin assignments from the distributor classification alone.
This product page consolidates verified distributor information, package details, supported CCD-driver functions, sourcing links, and engineering-oriented selection guidance. It distinguishes documented characteristics from unavailable electrical details so engineers can identify the correct device and request authoritative timing, pinout, and lifecycle information before committing a design.

典型应用
TMC57253DSB 适用于 6 应用s: CCD Scientific Imaging Systems, Industrial Machine Vision, Barcode and Document Scanners, Security and Surveillance Cameras, CCD Signal-Chain Readout Electronics, Legacy CCD Camera Electronics.
CCD Scientific Imaging Systems
The TMC57253DSB fits scientific CCD imaging systems that require a dedicated 5 V clock and output driver. Its documented 5/0 CMOS configuration, adjustable clock levels, TTL-compatible inputs, and CCD-compatible outputs support the timing interface between a CCD array and downstream sampling electronics. The high-speed clear function is relevant when the sensor must be reset rapidly between exposures. The serial-gate midlevel also supports correlated double sampling, where a controlled reference level helps the readout electronics distinguish signal and reset charge. Before layout, engineers must confirm the selected CCD's required waveforms, output levels, and timing relationships against the complete manufacturer datasheet.
Industrial Machine Vision
Industrial machine-vision modules can use the TMC57253DSB where a CCD sensor requires deterministic clock, clear, and gate-drive signals. The part's 5 V CMOS operation is compatible with conventional 5 V imaging electronics, while TTL-compatible inputs simplify command or timing-control interfacing. CCD-compatible outputs and adjustable clock levels provide the required boundary between the driver and the sensor. The commercial temperature grade makes the device a candidate for factory equipment, but enclosure temperature, vibration, and continuous operating-time requirements must be checked separately. Exact output timing, load capability, and pin-level routing remain unverified in the supplied excerpts and should be taken directly from the manufacturer data sheet.
Barcode and Document Scanners
The TMC57253DSB is suitable for legacy CCD-based barcode and document-scanning heads that depend on repeatable clocking and controlled transfer operations. Its adjustable clock levels allow the drive interface to be tuned to the imaging array, while the high-speed clear function supports the reset sequence used between scan lines. The serial-gate midlevel feature can assist correlated double sampling in low-level scanner readout circuits. Because the verified information identifies the required CCD functions but does not provide maximum clock frequency, output current, or propagation timing, engineers must validate those parameters against the sensor and scanner clocking architecture. The 24-HSOP package also requires compatible board space and assembly planning.
Security and Surveillance Cameras
CCD surveillance-camera modules represent a possible application for the TMC57253DSB because the device provides the clock, clear, and serial-gate-related functions required by many CCD readout systems. Its solid-state implementation supports repeatable operation without moving contacts, and the 5 V CMOS supply aligns with common camera-board power architectures. TTL-compatible control inputs can simplify integration with timing logic, while adjustable clock levels help match the selected sensor. Commercial temperature grading must be checked against the camera's internal temperature range. The supplied data does not state radiation, low-light, image-quality, or AEC-Q100 qualifications, so no such capability should be inferred for this device.
CCD Signal-Chain Readout Electronics
The TMC57253DSB can serve as the timing and output interface in a CCD signal-chain readout board that transfers charge from the imaging array toward correlated-double-sampling electronics. Its documented high-speed clear function supports sensor initialization, while its adjustable clock levels allow the output stage to be adjusted to the array's requirements. The serial-gate midlevel feature is directly relevant when the downstream amplifier must distinguish the serial sampling reference from signal charge. To use the part confidently, designers should confirm output impedance, settling behavior, clock-edge limits, and load capacitance from the original Texas Instruments data sheet. Those quantitative values are not available in the supplied distributor excerpts.
Legacy CCD Camera Electronics
The TMC57253DSB is a practical candidate for repairing or extending legacy CCD camera electronics that still use a Texas Instruments 24-HSOP driver. The part combines TTL-compatible inputs, CCD-compatible outputs, adjustable clock levels, high-speed clear, and serial-gate midlevel support in one 5 V CMOS device. That feature set targets the interface between a CCD and its readout circuitry rather than image processing itself. For an existing board, compare the original device's pinout, supply rails, clock polarity, output levels, and timing with the replacement documentation. Because no verified pin-to-pin substitute was identified, the safest path is an exact MPN replacement rather than a speculative cross-reference.

设计说明
Route the CCD clock, clear, and serial-gate outputs as short, controlled traces, and place the datasheet-specified bypass capacitors directly beside the associated 5 V and ground pins. Keep the solid-state driver return path close to the device so clock edges do not share noisy return paths with sensitive readout stages. The supplied web excerpts do not specify capacitor values or trace limits, so use the original manufacturer layout guidance rather than a generic decoupling recipe.
Verify clock amplitude, edge rate, duty cycle, and propagation timing against the selected CCD before finalizing the board. The TMC57253DSB provides adjustable clock levels, but adjustment alone does not establish timing compatibility with every sensor. Use controlled-impedance routing where appropriate, avoid long stubs, and maintain a continuous return reference. Account for the driver's output loading and the CCD input capacitance in signal-integrity simulations.
Do not substitute a generic 24-pin driver solely because it has a similar HSOP footprint. A valid replacement must match pin assignments, 5 V supply requirements, TTL input compatibility, CCD output levels, clear polarity and timing, serial-gate functionality, and adjustable clock behavior. No verified drop-in alternative was found in the supplied cross-reference results, so the exact MPN should be retained unless every electrical and timing requirement has been independently confirmed.
Use a clean 5 V supply and follow the manufacturer's decoupling and layout requirements. Clock-driver transitions can produce transient current even though the average load may appear modest, so power routing should be sized for edge current rather than only quiescent consumption. Separate noisy driver return current from analog sampling paths where the board architecture permits. The available excerpts do not specify peak output current, so those values must be obtained from the manufacturer datasheet.
合规信息
The supplied verified results do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not applicable because the part is identified as a commercial-grade interface IC and no automotive qualification is stated.
