Product details

PLL with integrated VCO — what it does on your board

The Texas Instruments SN74LV4046ADR is a phase-lock loop with an on-chip voltage-controlled oscillator, built in the 74LV low-voltage CMOS logic family. It accepts CMOS or TTL inputs and delivers CMOS or TTL outputs. The single PLL circuit provides a 1:3 input-to-output ratio.

Lifecycle and sourcing reality

TI lists this part as Active with ROHS3 compliance. No NRND flag, no last-time-buy notice as of the current record. That means it remains a safe line-item for new designs and production builds — no looming obsolescence risk.

Frequently asked questions

What is the maximum frequency of SN74LV4046ADR?

The VCO locks up to 38 MHz. That is the maximum VCO frequency; the PLL's capture and lock range must stay within that ceiling.

Is SN74LV4046ADR equivalent to CD4046?

Functionally similar — both are PLLs with VCO — but the SN74LV4046ADR is a low-voltage CMOS (74LV) part in a 16-SOIC package, while the classic CD4046 is a 4000-series CMOS part often in through-hole. The supply range, speed, and footprint differ; they are not direct equivalents.
