CAT24C04YI-GT3

onsemi · EEPROM · TSSOP-8

CAT24C04YI-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 CAT24C04 (this position is address input A0 on the CAT24C02).
2 A1 input Device address input that sets the device address when cascading multiple devices; pulled LOW internally when not driven.
3 A2 input Device address input that sets the device address when cascading multiple devices; pulled LOW internally when not driven.
4 VSS power_in Ground.
5 SDA bidirectional Serial data I/O pin that receives input data and transmits stored data; open drain in transmit mode, VIH up to 5.5 V.
6 SCL input Serial clock input that accepts the clock generated by the master; has a Schmitt trigger and noise suppression filter.
7 WP input Write protect input that inhibits all write operations when pulled HIGH; pulled LOW internally when not driven.
8 VCC power_in Power supply, 1.7 V to 5.5 V.
