ET1640 is listed in the Display Drivers range at ChipApex. The manufacturer field lists ETEK MICROELECTRONICS. Its product description is 8SEGs16 Grids,LED DRVR. Review the specifications below when checking this part for your BOM.
The ET1640 is an LED driver manufactured by ETEK MICROELECTRONICS, designed for driving 8-segment displays with a 16-grid configuration. It operates within a supply voltage range of 4.5V to 5.5V and supports up to 16 multiplexing steps. The device features a 2-wire serial interface for data transmission and includes memory chip select decoding capabilities. It is packaged in SOP-28 format.
Verify the specific package variant and ordering suffix against official ETEK documentation before procurement. Confirm that the 2-wire serial interface requirements match your system controller. Ensure operating voltage conditions align with the specified 4.5V to 5.5V range for reliable performance.
Select this component when a dedicated driver for 8-segment or 16-grid LED matrices is required. The integrated serial interface reduces pin count compared to parallel drivers. Verify compatibility with existing MCU GPIO configurations for the 2-wire protocol.
ETEK MICROELECTRONICS specializes in high-performance analog and power management ICs. The ET1640 belongs to their display driver portfolio, targeting applications requiring efficient LED control with minimal external components. This part complements other drivers like the ET6144 for different display densities.
Consult official substitution lists for direct equivalents. Generic replacements may differ in drive current or interface timing. Verify pinout compatibility if substituting with similar 28-pin LED drivers.
