It covers a count range from 2 to 2^24, giving the designer a wide window of timing intervals without cascading multiple devices. The 5 MHz maximum frequency sets the shortest achievable output period at 200 ns per count step, which is the practical ceiling for precision timing in this family. For longer delays, the 2^24 count ceiling extends the maximum interval to over 3 seconds at the same clock rate. ## 3 V to 18 V supply — one part for mixed-rail designs The supply range from 3 V to 18 V lets the CD4536BNSR operate directly on a 3.3 V logic rail, a 5 V microcontroller bus, or a 12 V industrial supply without an intermediate regulator. This eliminates a voltage-conversion stage in the timing path and reduces BOM count. Quiescent supply current is 3 mA typical, which is low enough for battery-backed real-time-clock applications where the timer runs continuously. The current draw does not vary significantly across the supply range — the CMOS construction keeps the bias current stable. The operating temperature range spans -55°C to 125°C, which is the military-grade envelope. This qualifies the part for avionics engine bays, downhole drilling tools, satellite payloads, and outdoor telecom cabinets where the ambient temperature swings beyond the industrial -40°C to 85°C band. ## Active lifecycle — no end-of-life risk on this BOM line The part is supplied in Tape & Reel (TR) or Cut Tape (CT) options, which matches automated pick-and-place assembly lines. Sourcing is per RFQ — confirm the BOM quantity and preferred packaging with your distributor at quote time.","metaTitle":"CD4536BNSR Programmable Timer IC – Texas Instruments, 5 MHz","metaDescription":"Texas Instruments CD4536BNSR programmable timer IC. 5 MHz max frequency, 3 V to 18 V supply, -55°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Type":"Programmable Timer","Count":"2 ~ 2²⁴","Package":"Tape & Reel (TR); Cut Tape (CT)","Frequency":"5MHz","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"3 mA","Voltage - Supply":"3V ~ 18V","Operating Temperature":"-55°C ~ 125°C","Supplier Device Package":"16-SO"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.82","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.82000","currency":"USD"},{"qty":10,"price":"$0.72000","currency":"USD"},{"qty":25,"price":"$0.67640","currency":"USD"},{"qty":100,"price":"$0.55190","currency":"USD"},{"qty":250,"price":"$0.51268","currency":"USD"},{"qty":500,"price":"$0.43632","currency":"USD"},{"qty":1000,"price":"$0.34906","currency":"USD"},{"qty":2000,"price":"$0.31633","currency":"USD"},{"qty":6000,"price":"$0.29452","currency":"USD"},{"qty":10000,"price":"$0.28361","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/08074128600efe59b0a7855cc31f796b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum frequency of the CD4536BNSR?","answer":"The maximum oscillator frequency is 5 MHz.
