Product details
Overview
THS7376IPW from Texas Instruments is a 4-channel video amplifier IC with one SD (CVBS) channel and three HD (Y'P'B'P'R'/G'B'R') channels, integrated sixth- and eighth-order low-pass filters, 6-dB fixed gain, rail-to-rail output, and 30.9-mA quiescent current at 3.3 V. It serves as a DAC reconstruction/ADC antialiasing filter in set-top boxes and Blu-ray players.
For engineers reviewing the THS7376IPW datasheet, THS7376IPW pinout, THS7376IPW application, or THS7376IPW equivalent, key selection criteria include SD/HD channel separation, 75-Ω drive capability per channel, HD bypass mode bandwidth (300 MHz), differential gain/phase performance (0.2%/0.3°), and TSSOP-14 package compatibility with THS7373/THS7374.
Technical Context
The THS7376IPW integrates four independent video amplifiers: one SD channel with sixth-order filter (–3 dB at 10 MHz) and three HD channels each with eighth-order filter (–3 dB at 42 MHz). All channels feature 6-dB gain, DC-coupled input/output support, and 210-mV output bias shift for full sync dynamic range.
Filter configuration is controlled via two logic inputs: DISABLE (pin 6) enables/disables all channels, and HD BYPASS (pin 9) toggles HD channels between filtered and bypassed modes (300 MHz –3 dB bandwidth); the SD channel filter is non-bypassable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| SD Filter Order & Bandwidth | Sixth-order LPF; –3 dB at 10 MHz - meets NTSC/PAL CVBS reconstruction requirements |
| HD Filter Order & Bandwidth | Eighth-order LPF; –3 dB at 42 MHz - supports 1080p30 Y'P'B'P'R' filtering |
| HD Bypass Bandwidth | –3 dB at 300 MHz - enables 1080p60 or SXGA RGB line driving without filtering |
| Differential Gain / Phase | 0.2% / 0.3° (NTSC/PAL) - preserves color fidelity in broadcast-quality video paths |
| Rail-to-Rail Output Swing | 3.1 V (75 Ω to GND) at 3.3 V supply - drives dual 75-Ω loads per channel |
| Quiescent Current | 30.9 mA at 3.3 V - enables low-power operation in portable/media center designs |
| ESD Protection | 10-kV HBM on outputs - robust against handling damage in production and field service |
Pinout & Package
TSSOP-14 package (PW suffix), RoHS-compliant, 5.0 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |

| 6 - DISABLE | Global enable/disable control | Logic high disables all channels (0.1 µA supply current); defaults to enabled if floating |
| 9 - HD BYPASS | HD filter mode control | Logic high bypasses all three HD filters; SD filter remains active and non-bypassable |
| 10 - VS+ | Positive supply | +3 V to +5 V single supply; PSRR = 50 dB (dc) |
| 5 - GND | Analog/digital ground | Common reference for all channels and logic inputs |
| 7,8 - NC | No connection | Not internally bonded; must remain unconnected |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS7373IPW | Same pinout and package; identical SD channel but only two HD channels (vs. three) | Limited to dual-HD-output systems (e.g., Y'P'B' only); cannot support full Y'P'B'P'R' or G'B'R') | Select when third HD channel is unused and cost reduction is prioritized |
| THS7374IPW | Same pinout and package; identical SD and HD channel count, but no HD BYPASS function | HD filters permanently enabled; no support for 1080p60/SXGA wideband RGB output | Select when system requires fixed filtering only and bypass flexibility is unnecessary |
Compared with THS7373IPW and THS7374IPW, the THS7376IPW uniquely provides three HD channels plus programmable HD bypass - enabling both broadcast-compliant filtering and high-bandwidth RGB routing in one footprint.

FAQ
What is the primary function of the THS7376IPW in a video system?
The THS7376IPW functions as a 4-channel video line driver and reconstruction/antialiasing filter IC. Its SD channel conditions CVBS signals with sixth-order filtering, while its three HD channels process Y'P'B'P'R' or G'B'R' components using eighth-order filters - all with 6-dB gain, rail-to-rail output, and 75-Ω drive capability. The THS7376IPW is used in set-top boxes, Blu-ray players, and media centers to ensure broadcast-compliant video signal integrity before output to displays or encoders.
Can the THS7376IPW drive two 75-Ω loads simultaneously per channel?
Yes, the THS7376IPW supports driving two 75-Ω loads per channel. Its rail-to-rail output stage delivers 3.1 V swing into a 75-Ω load at 3.3 V supply, and electrical characteristics confirm it can source/sink ≥100 mA - sufficient for dual-line driving. This capability enables use cases like feeding both a display and a recording path from a single HD channel without external buffers, directly supported by the THS7376IPW's design and test data.
How does the HD BYPASS pin affect THS7376IPW operation?
The HD BYPASS pin (pin 9) controls whether the three HD channels operate in filtered or wideband mode. When logic high, it bypasses the internal eighth-order low-pass filters, extending bandwidth to 300 MHz (–3 dB) - enabling 1080p60 or SXGA RGB video routing. The SD (CVBS) channel filter remains active and non-bypassable. This function is confirmed in the functional block diagram, logic table, and electrical characteristics tables for THS7376IPW.
What is the guaranteed differential gain and phase performance of the THS7376IPW?
The THS7376IPW guarantees differential gain ≤0.2% and differential phase ≤0.3° for both NTSC and PAL standards, measured at TA = +25°C with 3.3-V supply, RL = 150 Ω, and dc-coupled I/O. These values are 100% tested (test level A) and represent critical broadcast compliance metrics - directly specified in the "AC PERFORMANCE: SD (CVBS) CHANNEL" section of the THS7376IPW datasheet.
Is the THS7376IPW pin-compatible with other members of the THS737x family?
Yes, the THS7376IPW is pin-compatible with THS7373IPW and THS7374IPW in the TSSOP-14 (PW) package. Pin assignments for CVBS/HD I/O, power, ground, DISABLE, and HD BYPASS are identical across all three devices. This allows drop-in replacement where functionality aligns - for example, upgrading from THS7374IPW to THS7376IPW adds HD bypass capability without layout changes, as explicitly stated in the THS7376IPW datasheet.
