THS7374IPWR from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	CH1 IN	input	Channel 1 video input. Input resistance ~800 kΩ, input capacitance ~2 pF. Supports DC-coupled (with 300-mV output level shift), AC-coupled with sync-tip clamp, or AC-coupled with biasing.
2	CH2 IN	input	Channel 2 video input. Input resistance ~800 kΩ. Same input-coupling options as CH1 IN.
3	CH3 IN	input	Channel 3 video input. Input resistance ~800 kΩ. Same input-coupling options as CH1 IN.
4	CH4 IN	input	Channel 4 video input. Input resistance ~800 kΩ. Same input-coupling options as CH1 IN.
5	GND	power_in	Ground reference for all internal circuitry. Connect to system 0 V.
6	DISABLE	input	Chip-disable logic input. Logic high disables the part (~0.1 µA quiescent, high-Z outputs ≈20 kΩ
7	NC	unconnected	No internal connection. May be left floating or tied to GND.
8	NC	unconnected	No internal connection. May be left floating or tied to GND.
9	BYPASS	input	Filter-bypass logic input. Logic high bypasses the internal 6th-order 9.5-MHz low-pass filter (150-MHz bandwidth passthrough); logic low engages the filter. Must not be left floating - tie to GND or VS+. Filter/bypass switch time ~5 ns.
10	VS+	power_in	Positive single-supply pin. Operating range +3 V to +5 V (absolute max 5.5 V). Total quiescent current ~9.6 mA at 3.3 V, ~10 mA at 5 V. Bypass with local decoupling capacitors close to the pin.
11	CH4 OUT	output	Channel 4 video output. Rail-to-rail (swings within ~100 mV of the rails), 6-dB (2 V/V) gain. Capable of driving two 75-Ω lines simultaneously; short-circuit output current ~80-90 mA sourcing / 70-85 mA sinking.
12	CH3 OUT	output	Channel 3 video output. Rail-to-rail, 6-dB gain, drives two 75-Ω lines.
13	CH2 OUT	output	Channel 2 video output. Rail-to-rail, 6-dB gain, drives two 75-Ω lines.
14	CH1 OUT	output	Channel 1 video output. Rail-to-rail, 6-dB gain, drives two 75-Ω lines.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ths7374ipwr.step`	194 KB	You want the bare part, or you mark your own boards.
`ths7374ipwr-etched.step`	2.2 MB	You want the part with `THS7374IPWR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 583 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
