Overview
The CD40109BPW is a CMOS Quad Low-to-High Voltage Level Shifter produced by Texas Instruments. This device contains four independent low-to-high-voltage level-shifting circuits, each capable of shifting a low-voltage digital-logic input signal to a higher-voltage output signal. The CD40109BPW is notable for its flexibility in power supply sequencing and its ability to handle input signals that exceed both the low-voltage and high-voltage supply levels.
The device is available in a 16-pin Thin Shrink Small-Outline Package (TSSOP) and operates over a wide temperature range of -55°C to 125°C. It is designed to meet the requirements of JEDEC Tentative Standard No. 13B for 'B' Series CMOS Devices, ensuring reliable performance in various applications.
