TC1427CPA

Microchip Tech · Gate Drive ICs · PDIP-8

TC1427CPA 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 NC unconnected No connection.
2 IN A input Control input A, TTL/CMOS compatible logic input (VIH min 3V, VIL max 0.8V); ground or tie to VDD if unused.
3 GND power_in Ground; use a ground plane or individual ground returns for input and output circuits.
4 IN B input Control input B, TTL/CMOS compatible logic input (VIH min 3V, VIL max 0.8V); ground or tie to VDD if unused.
5 OUT B output Output B, CMOS totem-pole output with 1.2A peak current and latch-up withstand of 500 mA reverse current.
6 VDD power_in Supply input, 4.5V to 16V (absolute maximum +18V).
7 OUT A output Output A, CMOS totem-pole output with 1.2A peak current and latch-up withstand of 500 mA reverse current.
8 NC unconnected No connection.
