ICM7555IBA

Programmable Timers And Oscillators Overview

The Renesas ICM7555IBA is a single CMOS timer circuit designed for low-power applications. It operates within a supply voltage range of 2V to 18V and supports a maximum input frequency of 1MHz. The device features an output current capability of 20mA at low levels and -0.8mA at high levels. It is housed in an 8-pin SOIC package with dimensions of 5mm x 4mm x 1.5mm. The component functions as a standard timer, suitable for precision timing, pulse generation, and time delay tasks across a temperature range of -25°C to +85°C.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'IBA' against the manufacturer's official documentation to confirm pinout compatibility and electrical specifications relative to other variants like ICM7555IBAZ-T. Ensure the source document explicitly lists this part number to avoid confusion with obsolete or discontinued equivalents such as the ICM7555ESA.

Programmable Timers And Oscillators Selection Notes

Select this component when a low-power CMOS timer is required for battery-operated devices due to its wide voltage tolerance. Verify that the 20mA output drive is sufficient for the intended load, as it cannot directly drive high-current motors. Confirm that the SOIC-8 footprint matches the PCB design constraints.

Programmable Timers And Oscillators Part Context

The ICM7555 series represents a CMOS version of the classic 555 timer, offering significantly lower quiescent current compared to bipolar counterparts. This family includes variants like the dual-timer ICM7556. The ICM7555IBA is part of Renesas Electronics' portfolio, continuing the lineage from Intersil and Maxim Integrated products.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes include the ICM7555IBAZ-T. Other compatible options may include the ICM7555C-W-T from Maxim Integrated, provided the package and electrical parameters align with the design requirements.
