HT24C08ARZ

HTCSEMI · EEPROM · SOP-8

HT24C08ARZ from HTCSEMI, in a SOP-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 A0 input Address input pin. Not internally connected on the HT24C08; may be left floating or tied to VSS/VCC.
2 A1 input Address input pin. Not internally connected on the HT24C08; may be left floating or tied to VSS/VCC.
3 A2 input Hard-wire device address input. Tie to VSS or VCC to select one of two possible device addresses on the I2C bus. If left floating, internally read as VSS (low).
4 VSS power_in Ground / negative power supply return.
5 SDA bidirectional Serial data line. Open-drain bidirectional pin for I2C data transfer; requires an external pull-up resistor. May be wired-OR with other open-drain devices on the bus.
6 SCL input Serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. Supports up to 400kHz (Vcc 1.8-5V) or 1MHz (Vcc 2.5-5V).
7 WP input Write protect input. When tied to VCC, the full 8K memory array is write-protected. When tied to VSS or left floating, normal read/write operations are enabled.
8 VCC power_in Positive supply voltage input, 1.8V to 5.5V over -40C to +85C. Operating current 5mA max (write at 400kHz); standby current 3uA max.
