Clock frequency reaches 14 MHz, and propagation delay is 120 ns at 15 V with a 50 pF load. The 16-pin DIP package (16-PDIP) fits standard through-hole prototyping and legacy board revs. The 3 V to 18 V supply range is a key differentiator of the 4000B family. At 5 V the part works directly with TTL or 5 V CMOS logic without level translation. Propagation delay is specified at 120 ns with a 15 V supply and 50 pF load — expect longer delays at lower supply voltages, so budget margin for timing closure if running from a 5 V rail. Quiescent current is just 4 µA, so the part adds negligible static power draw in battery-backed or always-on sections. Output high/low current is 6.8 mA each, enough to drive a few CMOS gate inputs directly but not a heavy bus or LED without a buffer. Sourcing is through the independent distribution channel — surplus, new-old-stock, or broker inventory. For new designs, consider a more modern CMOS logic family (e.g., 74HC or 74HCT series) that offers similar D-type functionality in a through-hole package. The CD40175BE comes in a 16-pin PDIP (0.300\" width, 7.62 mm body) for through-hole mounting. Board layout follows standard 0.1\" pitch DIP footprint — no special pad geometry or thermal management needed for the 6.8 mA output current.","metaTitle":"CD40175BE D-Type Flip-Flop, 14 MHz, 3V–18V, -55°C to 125°C","metaDescription":"CD40175BE 4000B-series D-type flip-flop, 4-bit, positive-edge triggered, complementary outputs, 14 MHz clock, 120 ns prop delay at 15V, -55°C to 125°C.","metaKeywords":null},"attributes":{"series":"4000B","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Obsolete","categoryPath":["Logic ICs"],"specifications":{"Mfr":"Texas Instruments","Type":"D-Type","Series":"4000B","Package":"Tube","Function":"Master Reset","Output Type":"Complementary","Trigger Type":"Positive Edge","Mounting Type":"Through Hole","Package / Case":"16-DIP (0.300\\\", 7.62mm)","Product Status":"Active","Clock Frequency":"14 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 18V","Input Capacitance":"5 pF","Number of Elements":"1","Base Product Number":"CD40175","Operating Temperature":"-55°C~125°C(TA)","Supplier Device Package":"16-PDIP","Current - Quiescent (Iq)":"4 µA","Current - Output High, Low":"6.8mA, 6.8mA","Number of Bits per Element":"4","Max Propagation Delay @ V, Max CL":"120ns @ 15V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6900","priceTiers":[{"qty":1,"price":"$0.69000","currency":"USD"},{"qty":10,"price":"$0.58800","currency":"USD"},{"qty":25,"price":"$0.54920","currency":"USD"},{"qty":100,"price":"$0.43930","currency":"USD"},{"qty":250,"price":"$0.40788","currency":"USD"},{"qty":500,"price":"$0.34514","currency":"USD"},{"qty":1000,"price":"$0.26670","currency":"USD"},{"qty":2500,"price":"$0.24316","currency":"USD"},{"qty":5000,"price":"$0.22748","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c311023f367fbf030758d819981e0b82.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CD40175BE/alternatives.json"},"ai":{"faq":[{"question":"Is CD40175BE obsolete?","answer":"Yes, the CD40175BE is obsolete per Texas Instruments' product status. It is no longer manufactured, so new orders are fulfilled from surplus and broker stock through independent distribution."},{"question":"What is a replacement for CD40175BE?","answer":"There is no direct pin-compatible replacement announced by TI. For new designs, a 74HC175 or 74HCT175 D-type flip-flop in a 16-pin DIP package is a functional alternative, though supply voltage range differs (2 V to 6 V for 74HC). Check the specific logic family for timing and drive compatibility."},{"question":"Can CD40175BE be used with 5V supply?","answer":"Yes, the CD40175BE operates from 3 V to 18 V, so 5 V is within spec. At 5 V the propagation delay will be longer than the 120 ns figure given for 15 V; budget extra margin for timing closure."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD40175BE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD40175BE when reusing this data.
