TC4421CPA

Microchip Tech · Gate Drive ICs · PDIP-8

TC4421CPA from Microchip Tech, in a PDIP-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 VDD power_in Supply input rated 4.5V to 18V with respect to GND; duplicate VDD pins must both be connected and bypassed with a local ceramic capacitor of at least 1.0 µF suggested.
2 INPUT input High-impedance TTL/CMOS compatible control input with 300 mV of hysteresis between the high and low thresholds.
3 NC unconnected No connection.
4 GND power_in Ground return for bias current and high peak discharge currents; both GND pins must be connected and tied to a ground plane or very short traces.
5 GND power_in Ground return for bias current and high peak discharge currents; both GND pins must be connected and tied to a ground plane or very short traces.
6 OUTPUT output CMOS push-pull output driving capacitive loads with 9.0A peak current and withstanding 1.5A peak reverse current of either polarity; duplicate output pins must both be connected.
7 OUTPUT output CMOS push-pull output driving capacitive loads with 9.0A peak current and withstanding 1.5A peak reverse current of either polarity; duplicate output pins must both be connected.
8 VDD power_in Supply input rated 4.5V to 18V with respect to GND; duplicate VDD pins must both be connected and bypassed with a local ceramic capacitor of at least 1.0 µF suggested.

CAD (KiCad official)

  • Symbol: TC4421CPA
  • Footprint: Package_DIP:DIP-8_W7.62mm
  • 3D model: PDIP-8 (KiCad packages3D, STEP)
  • 3D model files: tc4421cpa-etched.step / tc4421cpa-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tc4421cpa.step / tc4421cpa.glb are the bare package body.

Provenance

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

  • Datasheet: Microchip Tech datasheet (24 pp, sha256 fdfdd968dd4e8796, retrieved 2026-10-31, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
