PCF8574T/3,518, Расширитель ввода/вывода шина I2C 8-бит 16SOIC

Описание PCF8574T/3,518 The PCF8574T/3.518 is a 8-bit remote I/O Expander for I?C-bus with interrupt. It provides general-purpose remote I/O expansion via the two-wire bidirectional I?C-bus (serial clock (SCL), serial data (SDA)). The devices consist of eight quasi-bidirectional ports, 100kHz I?C-bus interface, three hardware address inputs and interrupt output operating between 2.5 and 6V. The quasi-bidirectional port can be independently assigned as an input to monitor interrupt status or keypads or as an output to activate indicator devices such as LEDs. System master can read from the input port or write to the output port through a single register. The low current consumption of 2.5µA (typical, static) is great for mobile applications and the latched output ports directly drive LEDs. This is identical, except for the different fixed portion of the slave address. • I?C-bus to parallel port expander • 100kHz I?C-bus Interface (standard-mode I?C-bus) • Latched outputs directly drive LEDs • Total package sink capability of 80mA • Active low open-drain interrupt output • 2.5µA Typical low standby current • Latch-up testing is done to JEDEC standard JESD78 that exceeds 100mA • -40 to +85°C Operating temperature range EU RoHSCompliantECCN (US)EAR99Part StatusActiveHTS8542.39.00.01Number of I/Os8Number of Addresses8Manual ResetNoInterface TypeI2CInterface Speed (kHz)100I2C Bus Interface ModeStandard ModeInterrupt OutputYesOutput TypeOpen DrainMinimum Operating Supply Voltage (V)2.5Maximum Operating Supply Voltage (V)6Maximum Sink Current per Bit (mA)25(Typ)Maximum Source Current per Bit (mA)0.3Maximum Quiescent Current (uA)10Minimum Operating Temperature (°C)-40Maximum Operating Temperature (°C)85PackagingTape and ReelPin Count16Supplier PackageSOMountingSurface MountPackage Height2.45(Max)Package Length10.5(Max)Package Width7.6(Max)PCB changed16Lead ShapeGull-wingВес, г0.8
