It accepts eight parallel inputs and shifts them out serially on a single data line, controlled by a shift/load input and a clock. The complementary outputs give you both true and inverted serial data without extra inversion logic. Typical applications include reading multiple switch or sensor inputs over a few microcontroller pins, keypad scanning, and general-purpose I/O expansion in industrial control panels, PLC I/O modules, and embedded systems where board space is tight. ## Package and footprint — 16-TSSOP Housed in a 16-TSSOP package (4.40 mm body width), it is a surface-mount part. The supplier device package is also 16-TSSOP. ## Lifecycle and compliance — active, no LTB risk TI lists the SN74LV165APWRG3 as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window to track. For a BOM freeze, this part is a stable line item — no near-term need to qualify a second source unless you want dual-sourcing for supply resilience.","metaTitle":"SN74LV165APWRG3 8-bit shift register, 2V-5.5V, 16-TSSOP","metaDescription":"TI SN74LV165APWRG3 8-bit parallel-to-serial shift register, 74LV series, 2V to 5.5V supply, -40°C to 125°C, 16-TSSOP.

The LV version operates down to 2V supply and has lower dynamic power at 3.3V, while the HC version is specified for 2V to 6V and draws slightly higher supply current at the same frequency. For a 3.3V-only design the LV part is the lower-power pick; for a 5V rail the HC part is equally valid and may be cheaper on spot."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LV165APWRG3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LV165APWRG3 when reusing this data.
