Quiescent current is 17 mA typical across the supply range, and the outputs can source 1 mA or sink 20 mA — enough to drive one or two standard TTL loads or a 74F input without external buffers. The ROHS3 compliance confirms no restricted substances in the package or lead finish. ## Sourcing posture for BOM planning Texas Instruments lists the SN74F109D as an active product. No pin-compatible second-source is listed in the manufacturer's cross-reference data.","metaTitle":"SN74F109D Texas Instruments JK Flip-Flop, 150 MHz, 16-SOIC","metaDescription":"Active-production SN74F109D dual JK flip-flop with set/reset, 150 MHz clock, 8ns propagation delay, 4.5-5.5V supply, 16-SOIC.
