Supplied in a tube — the standard handling format for through-hole DIPs — which protects the leads during shipping and kitting. ## Sourcing and availability — quoted to order No stock-holding claim is made; availability is verified per inquiry.","metaTitle":"SN74LS126AN Texas Instruments 74LS Buffer, 3-State, 14-DIP","metaDescription":"SN74LS126AN Texas Instruments 74LS quad buffer, non-inverting, 3-state outputs, 4.75V-5.25V supply, 14-DIP.
