# TL7757CDR

**Texas Instruments** · Supervisor And Reset ICs · SOIC-8

TL7757CDR from Texas Instruments, in a SOIC-8. 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 | RESET | output | Reset output; becomes active (low) when VCC exceeds 1 V during power-up or when supply voltage drops below threshold voltage of 4.55 V ±120 mV; high output sink capability of 20 mA. |
| 2 | VCC | power_in | Supply voltage input; recommended operating range 1 V to 7 V. |
| 3 | NC | unconnected | No internal connection. |
| 4 | GND | power_in | Ground; reference voltage for the device. |
| 5 | NC | unconnected | No internal connection. |
| 6 | NC | unconnected | No internal connection. |
| 7 | NC | unconnected | No internal connection. |
| 8 | NC | unconnected | No internal connection. |

## CAD (KiCad official)

- Symbol: `TL7757CDR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `tl7757cdr-etched.step` / `tl7757cdr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tl7757cdr.step` / `tl7757cdr.glb` are the bare package body.
