The device converts logic levels between two voltage domains, each independently powered from 3V to 15V, enabling flexible level shifting between any combination of common logic voltages. Each direction (A-to-B and B-to-A) has an independent enable control, allowing fine-grained control over data flow. The 3-state outputs enable connection to shared buses. With a propagation delay of 120ns typical and wide -55 to 125 C operating temperature range, the CD40109BPWR is suitable for both commercial and industrial applications. The device is available in a 16-pin TSSOP package.","working_principle":"The CD40109BPWR operates as a bidirectional voltage level translator with independent power domains. Key subsystems include: (1) Four Bidirectional Channels - each channel can shift signals from A-side to B-side or B-side to A-side depending on the direction enable inputs; (2) Dual Power Rails - VDDA powers the A-side I\/O and VDDB powers the B-side I\/O, allowing independent voltage domains; (3) Direction Control - OA (output enable A-to-B) and OB (output enable B-to-A) independently control which direction is active; when both are disabled, outputs are in 3-state; (4) Level Translation - CMOS inverters on each side convert the input logic level to the appropriate output level referenced to the respective supply rail.","pin_description":"
