TL7705AIDR

Texas Instruments · Supervisor and Reset ICs · SOIC-8

TL7705AIDR from Texas Instruments, in a SOIC-8. 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 REF output Voltage reference output (Vref = 2.53 V typ). Requires a decoupling capacitor (typically 0.1 uF) to GND to reduce influence of fast supply transients.
2 RESIN input Active-low reset input. Forces the RESET/RESET outputs active when driven low; VIH >= 2 V, VIL <= 0.6 V, input current up to 20 uA.
3 CT passive External timing-capacitor pin. Reset pulse duration t_d (seconds) = 1.3e4 * C_T (farads); e.g. 0.1 uF gives t_d ~ 1.3 ms.
4 GND power_in Device ground reference.
5 RESET output Active-low supervisor reset output (inverted). Open-collector; typically pulled up externally (e.g. 10 kOhm). IOL = 16 mA, VOL <= 0.4 V.
6 RESET output Active-high supervisor reset output. Open-collector; requires external pull-up. IOH = -16 mA, VOH >= VCC - 1.5 V.
7 SENSE input Supply-monitoring sense input. Compared against internal threshold; for TL7705A negative-going threshold VIT- = 4.55 V typ (hysteresis ~15 mV). Input range 0 to 10 V.
8 VCC power_in Positive supply input. Recommended VCC = 3.5 V to 18 V (absolute max 20 V). Typical supply current ICC = 1.8 mA.

Two STEP files. Same geometry, different body top:

File Size Use it when
tl7705aidr.step 122 KB You want the bare part, or you mark your own boards.
tl7705aidr-etched.step 1.7 MB You want the part with TL7705AIDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 436 faces against 147 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (29 pp, sha256 520a7378835d9638, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
