Product details
Overview
THS7365IPWR from Texas Instruments is a 6-channel video amplifier IC with three standard-definition (SD) and three high-definition (HD) channels, each featuring bypassable sixth-order Butterworth low-pass filters (–3 dB at 9.5 MHz for SD, 36 MHz for HD), 6-dB fixed gain, rail-to-rail output swing, and single-supply operation from +2.7 V to +5 V. It serves as a video line driver in set-top box and Blu-ray player output buffering.
For engineers reviewing the THS7365IPWR datasheet, THS7365IPWR pinout, THS7365IPWR application, or THS7365IPWR equivalent, key selection considerations include SD/HD channel separation, filter bypass control logic, 75-Ω driving capability per channel, differential gain/phase performance (0.2%/0.3°), and TSSOP-20 package thermal characteristics.
Technical Context
The THS7365IPWR integrates six independent video amplifiers-three optimized for SD signals (CVBS, S-Video Y'/C', 480i/576i) and three for HD signals (Y'/PB/PR, 720p/1080i/1080p30)-each with dedicated sixth-order LPF and individual enable/bypass controls. Its SiGe BiCom3X process enables low quiescent current (20.7 mA at 3.3 V) while maintaining rail-to-rail output swing within 100 mV of rails.
Input coupling supports DC-coupled mode with 300-mV output level shift, AC-coupled sync-tip clamp for CVBS/Y'/R'G'B', or external-bias AC coupling for C'/PB/PR. Logic inputs (Disable SD/HD, Bypass SD/HD) are TTL-compatible and must not float; enable/disable timing is under 140 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | +2.7 V to +5 V single supply: Enables direct integration into 3.3-V or 5-V video subsystems without level-shifting. |
| SD filter –3 dB bandwidth | 9.5 MHz: Matches NTSC/PAL DAC reconstruction and anti-aliasing requirements for 480i/576i signals. |
| HD filter –3 dB bandwidth | 36 MHz: Supports full bandwidth of 720p/1080i signals with <0.1% differential gain error. |
| Gain | 6 dB (2×): Fixed non-inverting gain simplifies PCB layout and eliminates external feedback component variation. |
| Rail-to-rail output swing | Swings within 100 mV of rails: Allows direct driving of 75-Ω loads with AC or DC coupling and full sync-tip dynamic range. |
| Total quiescent current | 20.7 mA at 3.3 V: Enables low-power video buffering in portable or thermally constrained consumer devices. |
| Differential gain/phase | 0.2%/0.3° (NTSC): Meets broadcast-grade color fidelity requirements without post-amplifier correction. |
Pinout & Package
TSSOP-20 package (RoHS-compliant, green, lead-free); 6.5 mm × 4.4 mm footprint with 0.65 mm pitch; thermal pad not present; JEDEC MS-013 variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 (SD1–3 IN) | SD video input | Accepts CVBS, Y', or R'G'B' baseband signals; supports DC-coupled (300-mV shift) or AC-coupled (sync-tip clamp) biasing. |
| 7, 8, 9 (HD1–3 IN) | HD video input | Accepts Y'/PB/PR or G'B'R' signals; AC-coupling requires external resistor to VS+ for bias. |
| 20, 19, 18 (SD1–3 OUT) | SD video output | Drives 75-Ω loads directly; rail-to-rail swing supports both AC- and DC-coupled termination. |
| 12, 13, 14 (HD1–3 OUT) | HD video output | Delivers full HD bandwidth with <0.1% differential gain; output impedance ≤1.7 Ω at 30 MHz in filter mode. |
| 10 (Bypass SD) | SD filter control | Logic high disables all three SD channel filters; must be tied to VS+ or GND-no floating allowed. |
| 11 (Bypass HD) | HD filter control | Logic high disables all three HD channel filters; 5-ns switching time enables real-time format adaptation. |
| 17 (Disable SD) | SD channel shutdown | Logic high disables SD outputs (IQ drops to 6.9 mA max); used for power gating during HD-only operation. |
| 15 (Disable HD) | HD channel shutdown | Logic high disables HD outputs (IQ drops to 13.8 mA max); supports dynamic power scaling in multi-format systems. |
| 5 (VS+) | Positive supply | Accepts 2.7–5 V; decoupling capacitor required at pin for stability across SD/HD bandwidths. |
| 16 (GND) | Ground reference | Common return for all analog and digital circuitry; requires low-impedance PCB plane connection. |
Key Features
| Feature | Design Value |
|---|---|
| Six independent video channels | Three SD + three HD paths allow simultaneous processing of legacy and modern video formats without multiplexing delay. |
| Bypassable sixth-order Butterworth filters | Enables system-level flexibility: use filters for DAC reconstruction or bypass for ADC sampling paths. |
| Rail-to-rail output stage | Supports both AC-coupled (capacitor-coupled) and DC-coupled (direct-connected) 75-Ω video loads without external level-shifting. |
| Sync-tip clamp for AC-coupled inputs | Preserves black-level accuracy on CVBS/Y'/R'G'B' inputs without external clamping diodes or timing circuits. |
| Low-power disable modes | 0.1 µA shutdown current when both SD and HD are disabled-critical for battery-backed video standby states. |
Applications
| Set-Top Box Output Buffering | PVR/DVR Output Buffering |
|---|---|
Use Scenario: Driving composite (CVBS), S-Video (Y'/C'), and component (Y'/PB/PR) outputs from a single SoC in a cable/satellite STB.

Equivalent & Alternatives
The following parts are listed as comparable options for similar video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS7356IPW | 3-channel SD-only amplifier; no HD channels or HD filters; same TSSOP-20 package and 6-dB gain. | Limited to CVBS/S-Video outputs only; cannot support Y'/PB/PR or 720p/1080i signals. | Select when system requires SD output only and board space/power budget precludes unused HD channels. |
| LMH0387SQ/NOPB | 3G-SDI reclocker with integrated cable driver; no analog video filtering; operates at 2.97 Gbps serial rate. | Designed for digital serial video transport-not baseband analog buffering-requiring serializer/deserializer pairing. | Select for digital video backhaul over coax; not a functional substitute for analog baseband amplification and filtering. |
Compared with THS7365IPWR, THS7356IPW offers identical SD performance in smaller footprint but lacks HD capability, while LMH0387SQ/NOPB addresses digital video infrastructure rather than analog line driving-neither is pin-compatible nor functionally interchangeable.

FAQ
What is the maximum operating temperature for the THS7365IPWR?
The THS7365IPWR is rated for continuous operation from –40°C to +85°C ambient temperature. Its maximum junction temperature for long-term reliability is +125°C, and absolute maximum junction temperature under any condition is +150°C. Thermal design must ensure θJA ≤ 88°C/W (JEDEC High-K board) to maintain safe silicon temperatures at full load.
Can the THS7365IPWR drive two 75-Ω loads simultaneously per channel?
Yes, the THS7365IPWR is explicitly designed to drive two 75-Ω video lines per channel. Its rail-to-rail output stage delivers ±90 mA output current and maintains specified differential gain/phase (0.2%/0.3°) and group delay variation (<10 ns) under this dual-load condition, as confirmed in TI's SBOS467 datasheet Figure 1 and Electrical Characteristics tables.
How does the sync-tip clamp function on THS7365IPWR SD inputs?
The THS7365IPWR implements an internal transparent sync-tip clamp on SD inputs (pins 1–3) for AC-coupled CVBS, Y', or R'G'B' signals. When enabled, it restores DC level using the sync tip without external components, preserving black-level accuracy. Clamp charge current is 140–200 µA at –0.1 V input, and the feature is inactive in DC-coupled or bypass modes.
What is the purpose of the NC pins on the THS7365IPWR TSSOP-20 package?
Pins 4 and 6 of the THS7365IPWR are designated NC (no internal connection). TI's datasheet recommends connecting them to GND for mechanical stability and noise immunity-though they carry no electrical function. Leaving them floating is not advised, as it may increase susceptibility to EMI or cause unintended coupling in high-density layouts.
Does the THS7365IPWR support DC-coupled input with AC-coupled output?
Yes, the THS7365IPWR supports mixed coupling configurations. Its 300-mV output level shift enables DC-coupled inputs while driving AC-coupled 75-Ω loads via series capacitors. This configuration preserves full sync-tip dynamic range at the output even with 0-V input, eliminating need for external level-shifters or bias networks in hybrid signal paths.
