Available from SC-70 and SON up to SOIC and TSSOP packages.

Low-voltage logic for dense 3.3 V and mixed-voltage boards

Use this SN74LVC page to compare TI logic variants by function, channel count, package, voltage range, and output drive.

The SN74LVC family from Texas Instruments is built for modern low-voltage digital interfaces where 5 V TTL logic is no longer the default rail. The catalog spans simple single-gate devices, quad NAND and NOR gates, hex inverters, octal buffers, bus transceivers, latches, flip-flops, multiplexers, and small logic translators. Typical variants support 1.65 V to 3.6 V operation, making them useful on 1.8 V, 2.5 V, and 3.3 V processor, FPGA, memory, and peripheral buses.

Engineers usually choose SN74LVC when they need CMOS logic speed, compact packaging, and predictable switching behavior without moving to a 5 V logic family. Many options provide strong 24 mA class output drive, 3-state outputs for shared buses, Schmitt-trigger inputs for noisy edges, or 5 V tolerant inputs on selected functions. The same base family appears in SOIC, TSSOP, VSSOP, SOT-23, SC-70, SON, VQFN, and BGA packages, so it can serve both serviceable industrial boards and dense handheld electronics.

When selecting a SN74LVC variant, start with the logic function and bit width, then confirm input tolerance, output enable behavior, propagation delay, package pitch, and temperature grade. Octatronics groups the ordering codes under one base number so procurement and engineering teams can compare active variants, alternate packages, and stock positions without losing the original TI naming context.

How to Choose the Right SN74LVC Drivers, Receivers and Transceivers

cpu

Choose by logic role

Match the Boolean function, bit width, inversion, and output-enable behavior before comparing package alternatives.

zap

Check rail compatibility

Confirm the supply range and input tolerance for the exact suffix, especially on mixed 3.3 V and 5 V systems.

activity

Validate timing margin

Use propagation delay and output drive current from the datasheet for high-speed buses or long traces.

Frequently Asked Questions

Common technical questions about the SN74LVC product family.

SN74LVC devices are low-voltage CMOS logic ICs used for gates, buffers, bus transceivers, latches, translators, and small interface logic on 1.8 V to 3.3 V digital boards.
Sometimes, but only after checking supply voltage, input thresholds, output drive, timing, pinout, and input tolerance. SN74LVC is optimized for lower voltage rails, while HC and LS families target different logic levels.
The base family covers many logic functions and each function may be offered in multiple package, temperature, and reel formats. The suffix identifies the exact mechanical and ordering option.
