LMH1981MT from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | REXT | passive | Bias current external resistor, specified with REXT = 10 kΩ 1% to ground-referenced bias in the electrical characteristics. |
| 2 | GND | power_in | Ground; all voltages are measured with respect to GND. |
| 3 | VCC1 | power_in | Supply voltage pin, operating range 3.3V −5% to 5V +5% with absolute maximum of 5.5V. |
| 4 | VIN | power_in | Video input accepting 140 mV to VCC-VIN-CLAMP amplitude with 0.7 V sync tip clamp level, absolute maximum −0.3V to VCC + 0.3V. |
| 5 | GND | power_in | Ground; all voltages are measured with respect to GND. |
| 6 | VCC2 | power_in | Supply voltage pin, operating range 3.3V −5% to 5V +5% with absolute maximum of 5.5V. |
| 7 | HSOUT | output | Horizontal sync output with very low jitter on its leading (falling) edge, CMOS logic swinging rail-to-rail. |
| 8 | VSOUT | output | Vertical sync output, negative-polarity CMOS logic with a pulse width of 3 H periods. |
| 9 | VFOUT | output | Video format output conveying the total horizontal line count per field as an 11-bit binary serial data stream. |
| 10 | GND | power_in | Ground; all voltages are measured with respect to GND. |
| 11 | VCC3 | power_in | Supply voltage pin, operating range 3.3V −5% to 5V +5% with absolute maximum of 5.5V. |
| 12 | CSOUT | output | Composite sync output, negative-polarity CMOS logic swinging rail-to-rail. |
| 13 | BPOUT | output | Burst/back porch timing output, negative-polarity CMOS logic swinging rail-to-rail. |
| 14 | OEOUT | output | Odd/even field output, CMOS logic swinging rail-to-rail (not negative-polarity). |
