It belongs to the TPIC series, TI's power-logic family that integrates high-current output stages with standard shift-register control logic. The part accepts serial data input and shifts it through an 8-bit register, then latches the parallel data onto eight open-drain output stages. ## Open-drain outputs — the design difference The open-drain output stage is the defining characteristic that separates this part from a standard 74HC595 shift register. Each of the eight outputs can sink substantial current — rated for 150 mA per output continuously — and the outputs can be paralleled for higher load currents on a single channel. The open-drain configuration means the outputs pull low only; the load connects between the output pin and a positive supply voltage (up to the output breakdown voltage, typically 50 V). This allows the TPIC6B595N to switch loads at a different voltage than the logic supply, a capability a push-pull shift register cannot match. The through-hole 20-pin DIP package (0.300\" body width) suits prototyping, breadboard work, and legacy PCB retrofits where surface-mount rework is impractical. The industrial temperature range also covers the thermal extremes in sealed enclosures with minimal airflow.","metaTitle":"TPIC6B595N Power 8-Bit Shift Register, Open-Drain, 20-PDIP","metaDescription":"Texas Instruments TPIC6B595N power logic 8-bit shift register with open-drain outputs. 4.5V-5.5V supply, -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":"TPIC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Series":"TPIC","Package":"Tube","Function":"Serial to Parallel, Serial","Logic Type":"Shift Register","Output Type":"Open Drain","Mounting Type":"Through Hole","Package / Case":"20-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Elements":"1","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"20-PDIP","Number of Bits per Element":"8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.77","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.77000","currency":"USD"},{"qty":10,"price":"$1.59000","currency":"USD"},{"qty":25,"price":"$1.50000","currency":"USD"},{"qty":100,"price":"$1.27790","currency":"USD"},{"qty":250,"price":"$1.19988","currency":"USD"},{"qty":500,"price":"$1.04990","currency":"USD"},{"qty":1000,"price":"$0.86991","currency":"USD"},{"qty":2500,"price":"$0.80992","currency":"USD"},{"qty":5000,"price":"$0.77992","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/afc31590f8865205eb8d8974843f460c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How does TPIC6B595N compare to a standard 74HC595 shift register?","answer":"The TPIC6B595N is a power-logic device with open-drain outputs rated for 150 mA per channel, whereas a 74HC595 has push-pull outputs limited to around 6 mA. The TPIC6B595N drives loads directly — relays, solenoids, LEDs — without external transistors. The 74HC595 is a logic-level part for signal routing only. They are not pin-compatible: the TPIC6B595N uses a different pinout with dedicated power and ground pins for the output stage."},{"question":"Can TPIC6B595N be used with 5V microcontrollers?","answer":"The logic inputs are 5 V tolerant and the serial interface (data in, clock, latch, output enable) connects directly to 5 V GPIO pins without level shifting."},{"question":"What is the difference between TPIC6B595N and TPIC6B595D?","answer":"The TPIC6B595N is in a 20-pin PDIP through-hole package; the TPIC6B595D is the same die in a 20-pin SOIC surface-mount package. Electrical specifications are identical. The choice is purely a board-assembly decision — through-hole for prototyping or legacy boards, SOIC for automated SMT production."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPIC6B595N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPIC6B595N when reusing this data.
