40109 Quad Level Shifter PDIP-16
The 40109 Quad Level Shifter is a CMOS logic integrated circuit in a 16-pin PDIP package featuring four independent low-to-high voltage translators. Designed to shift digital logic signals from a lower input voltage domain to a higher output voltage domain, this device supports a wide supply range typically from 3 V to 18 V, offering flexibility for interfacing between different logic families and power domains. Each channel provides non-inverting level translation with tri-state output capability, enabling efficient bus interfacing and isolation of subsystems. The IC’s CMOS construction ensures low power consumption and high input impedance, making it suitable for a variety of digital signal conditioning and voltage translation applications.
