TPS65198RUYR - 13-Channel LCD Level Shifter | Texas Instruments
MPN: TPS65198RUYR ✓ Hoạt độngTPS65198RUYR Tóm tắt
A level shifter is an interface IC that translates logic signals between voltage domains whose high and low thresholds differ. In an LCD television or monitor, source electronics, timing controllers, panel interfaces, and backlight systems may operate from different supply rails. A multi-channel level shifter allows those signals to cross between incompatible voltage domains, while the integrated operational amplifier provides buffering for a signal that requires drive or amplification.
The TPS65198RUYR's 13-channel architecture consolidates multiple translated logic connections in one package. This can reduce the number of discrete level-shifter components and simplify printed-circuit-board layout compared with a collection of individual translators. Its 4 x 4 mm WQFN format also supports compact display-control designs where connector density and panel-interface routing leave limited board area.
The verified operating temperature range is -40 C to +85 C, covering industrial temperature conditions commonly encountered in display electronics. The available LCSC listing identifies an 8 V to 20 V supply-related value, but the provided source excerpt does not clearly identify that parameter or its test conditions; consequently, voltage limits, channel direction, translation thresholds, and the integrated amplifier's electrical ratings require confirmation in the manufacturer datasheet before design release.
Typical uses include LCD monitor panel-interface circuits, television timing and control boards, display power-sequence logic, and other multi-rail display systems where a compact level-translation stage is needed. Because this device combines translation and amplification, it can simplify signal-interface design when the source impedance and loading requirements of the translated channels differ.
Engineers should confirm every channel's direction, voltage domain, enable behavior, and the exposed-pad connection directly against the TI datasheet and the PCB footprint. The 28-pin WQFN package is also thermally and assembly sensitive; proper land-pattern compliance, paste control, and exposed-pad soldering are required for reliable production yield.
This page consolidates the verified manufacturer identification, distributor package data, temperature rating, and supply-range excerpt for TPS65198RUYR, while clearly separating missing electrical data from confirmed values. It also documents the absence of a manufacturer-verified drop-in substitute rather than presenting an unverified package conversion as a drop-in replacement.

Ứng dụng tiêu biểu
TPS65198RUYR phù hợp cho 6 Áp dụngs: LCD Monitor Panel Interfaces, LCD Television Timing-Control Boards, Multi-Rail Display Control Logic, Panel Driver Command Interfaces, Display Backlight Sequencing Control, Industrial Flat-Panel Display Systems.
LCD Monitor Panel Interfaces
The TPS65198RUYR fits an LCD monitor board that must translate several panel-control signals between the timing controller and lower-voltage display interface circuitry. Its 13 translated channels allow multiple related signals to share one 28-pin WQFN (RUY) device, while the integrated operational amplifier can buffer a channel that needs additional drive. The -40 C to +85 C rating covers industrial-temperature monitor environments. Before schematic release, engineers must confirm channel directions, enable behavior, and the 8 V to 20 V supply-related value directly in the TI datasheet because the retrieved distributor excerpt does not fully define its test conditions.

LCD Television Timing-Control Boards
In an LCD television main board, the TPS65198RUYR can translate control and status signals between the main processor, timing controller, and panel-interface circuitry operating at different logic levels. Thirteen channels reduce the number of separate translator packages, and the 4 x 4 mm WQFN (RUY) footprint preserves routing space in densely populated televisions. The integrated amplifier is useful where a translated signal also requires buffering. Confirm every channel's voltage domain and direction against the official datasheet, and route exposed-pad connections exactly as specified for both electrical and thermal reliability.
Được đề xuất
Multi-Rail Display Control Logic
The TPS65198RUYR is appropriate for display boards that divide logic functions across multiple voltage domains, such as a controller rail, timing rail, and panel-driver rail. Its 13-channel architecture translates multiple signals without requiring thirteen discrete translator packages, and the integrated op-amp provides an additional buffered path within the same component. This can shorten board traces and simplify assembly. The verified -40 C to +85 C rating is useful across industrial display installations, but designers should confirm per-channel thresholds and signal timing before relying on the device for high-speed data rather than control signals.
Được đề xuất
Panel Driver Command Interfaces
A panel-driver command interface often links a timing controller operating at one voltage to gate-driver logic operating at another. The TPS65198RUYR can translate up to 13 associated command signals in one package, and its integrated amplifier can support a buffered interface line. Compared with a collection of single-channel translators, the 28-pin WQFN (RUY) implementation occupies a compact 4 x 4 mm footprint and can simplify bill-of-material management. Verify the exact channel mapping, directional constraints, and allowable input and output voltage combinations in the TI datasheet before layout release.
Được đề xuất
Display Backlight Sequencing Control
The TPS65198RUYR can support level translation between display-control logic and backlight sequencing or panel-enable circuitry when the two sections use different voltage domains. Its 13 channels allow several sequencing and status lines to cross the boundary efficiently, while the integrated operational amplifier can provide a buffered control output where required. The -40 C to +85 C range suits industrial display systems. Engineers should confirm that the relevant channels support the required direction and timing, and that the amplifier is not being assigned to a function outside its datasheet limits.
Được đề xuất
Industrial Flat-Panel Display Systems
Industrial monitors and control panels often combine a high-performance controller with interface circuits operating at different logic voltages, making the TPS65198RUYR useful for a consolidated translation stage. Its -40 C to +85 C operating range matches industrial-temperature requirements, and the 28-pin WQFN package fits space-constrained flat-panel electronics. The device's 13 channels can replace several discrete translators, and the integrated amplifier can reduce external buffering in suitable locations. Because the retrieved data does not confirm individual pin assignments, the schematic and PCB layout must be checked against the official pin map and package drawing.

Bảo phân biệt quan trọng
- Combines thirteen level-shifting channels and an amplifier in one display-specific IC (vsGeneric single-channel level-shifter combinations)
- Purpose-built for LCD television and monitor interfaces (vsGeneral-purpose logic translators)
- Compact 28-pin WQFN implementation (vsDiscrete translator and buffer packages)
Ghi chú thiết kế
Use the official TI RUY 28-pin WQFN land pattern rather than a generic 28-pin footprint. Confirm whether the exposed pad is electrically connected, its thermal and copper requirements, and the manufacturer-recommended solder-mask and paste apertures. The verified 4 x 4 mm body size is not enough to define a production-compatible footprint, and a copied footprint without the exposed-pad geometry can cause assembly defects or unstable thermal performance.
Map all 13 translated channels and the integrated operational amplifier before assigning signals. Do not assume every channel has the same direction, enable behavior, output-impedance specification, or voltage tolerance; these details were not available in the retrieved excerpts. Place the device near the boundary between the two voltage domains, keep high-speed traces short, and provide a continuous return path beneath each interface route to reduce crosstalk and ground bounce.
The retrieved LCSC excerpt reports 8 V to 20 V, but it does not unambiguously identify the associated supply pin or test conditions. Do not use that value as permission to connect an external rail until the TI datasheet identifies the correct power terminals, absolute maximum ratings, and operating limits. Likewise, treat TPS65198RUYT as a review candidate rather than an automatic replacement because the available comparison states that important parameters and circuit details can differ.
Thông tin tuân thủ
The supplied verified snippets do not state RoHS, REACH, halogen-free, lead-free, conflict-minerals, or AEC-Q100 status. The part is described for LCD TVs and monitors rather than automotive use, so AEC-Q100 is treated as not applicable without asserting a qualification.
