CAT24C16YI-GT3

onsemi · EEPROM · TSSOP-8

CAT24C16YI-GT3 from onsemi, in a TSSOP-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 connect on the CAT24C16, since the A0 address input is not used on this density.
2 NC unconnected No connect on the CAT24C16, since the A1 address input is not used on this density.
3 NC unconnected No connect on the CAT24C16, since the A2 address input is not used on this density.
4 VSS power_in Ground.
5 SDA bidirectional Serial data input/output that is open drain when transmitting; data is acquired on the positive edge and delivered on the negative edge of SCL.
6 SCL input Serial clock input that accepts the clock generated by the I2C master, supporting 100 kHz Standard and 400 kHz Fast modes.
7 WP input Write protect input that inhibits all write operations when pulled HIGH and is pulled LOW internally when not driven.
8 VCC power_in Power supply, 1.7 V to 5.5 V.
