Product Summary

The MCP23008T-E is a 8-bit I/O expander. The MCP23008T-E differs in the number of ardware address pins and the serial interface. The MCP23008T-E consists of multiple 8-bit configuration registers for input, output and polarity selection.

Parametrics

MCP23008T-E absolute maximum ratings: (1) Ambient temperature under bias: -40 to +125°C; (2) Storage temperature: -65 to +150°C; (3) Voltage on VDD with respect to VSS: -0.3V to +5.5V; (4) Voltage on all other pins with respect to VSS (expect VDD) : -0.6V to (VDD +0.6V) ; (5) Total power dissipation: 700mW; (6) Maximum current out of VSS pin: 150mA; (7) Maximum current into VDD pin: 125mA; (8) Input clamp current, IIK ( VI＜0 or VI＞VDD) : ±20mA ; (9) Output clamp current, IOK (VO＜0 or VO＞VDD) : ±20mA; (10) Maximum output current sunk by any output pin: 25mA; (11) Maximum output current sourced by any output pin: 25mA.

Features

MCP23008T-E features: (1) 8-bit remote bidirectional I/O port; (2) High-speed SPI interface; (3) Hardware address pins; (4) Configurable interrupt output pin; (5) Configurable interrupt source; (6) Polarity Inversion register to configure the polarity of the input port data; (7) External reset input; (8) Low standby current: 1|ìA (max.) .
