It accepts a supply range from 3V to 18V, which lets it interface between 5V TTL, 12V industrial logic, and 15V analog rails without a level shifter. Each of the six buffers can source 8mA and sink 48mA, enough to drive a small relay coil through a transistor, a string of LEDs, or a long backplane trace. ## 3V to 18V supply — one buffer for multiple logic families The CD4050BE operates from 3V to 18V supply. ## 8mA source / 48mA sink — real drive for real loads The output drive is generous for a CMOS buffer. The 48mA sink capability can directly energise a 24V relay coil through a series resistor and a small-signal transistor, or drive a bank of low-current LEDs. The 8mA source is enough to charge the gate capacitance of a logic-level MOSFET or feed a 5V TTL input. For heavier loads, the push-pull stage can be paralleled across multiple buffers (same input) to increase drive — just watch the package thermal limits. ## Through-hole DIP — still the repair-bench and breadboard standard The 16-pin DIP package (0.300\" width, 7.62mm row spacing) is a legacy footprint that remains common in industrial control cards, test equipment, and prototyping. It fits standard breadboards, wire-wrap sockets, and IC extraction tools. For repair depots and MRO shops, this means the part can be swapped without hot-air rework — a soldering iron and a desoldering pump are enough. ## Active lifecycle — no near-term EOL risk For long-life programs in industrial, aerospace, or defence, this part is a safe line item to qualify into the BOM. If a second-source concern arises, the 4000B series is broadly second-sourced by multiple manufacturers — the CD4050BE pinout is standard across the industry.","metaTitle":"CD4050BE Buffer Non-Inverting, 3V-18V, 16-DIP, Active","metaDescription":"Texas Instruments CD4050BE 4000B series hex buffer, non-inverting push-pull output, 3V to 18V supply, -55°C to 125°C, 8mA/48mA drive, 16-DIP.","metaKeywords":null},"attributes":{"series":"4000B","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"4000B","Package":"Tube","Logic Type":"Buffer, Non-Inverting","Output Type":"Push-Pull","Mounting Type":"Through Hole","Package / Case":"16-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 18V","Number of Elements":"6","Operating Temperature":"-55°C ~ 125°C (TA)","Supplier Device Package":"16-PDIP","Current - Output High, Low":"8mA, 48mA","Number of Bits per Element":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.64","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.64000","currency":"USD"},{"qty":10,"price":"$0.56000","currency":"USD"},{"qty":25,"price":"$0.52560","currency":"USD"},{"qty":100,"price":"$0.42910","currency":"USD"},{"qty":250,"price":"$0.39856","currency":"USD"},{"qty":500,"price":"$0.33920","currency":"USD"},{"qty":1000,"price":"$0.27136","currency":"USD"},{"qty":2500,"price":"$0.24592","currency":"USD"},{"qty":5000,"price":"$0.24000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/cee5e635680f5c2543b21b033300d6fe.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can CD4050BE operate at 5V supply?","answer":"Yes.
