SN74LV Low-Voltage CMOS Logic Variants
Texas Instruments SN74LV devices provide low-voltage CMOS gates, buffers, multiplexers, counters, and bus logic for 2 V to 5.5 V systems that need compact packages and moderate drive.
Low-voltage logic bridging classic 5 V and modern 3.3 V designs
Compare SN74LV functions, packages, propagation delays, and supply ranges across TI ordering variants.
The SN74LV family is Texas Instruments' low-voltage CMOS logic line for designs that operate across a wider 2 V to 5.5 V supply window than many newer 3.3 V-only logic families. It includes standard gates, inverters, buffers, flip-flops, multiplexers, counters, bus transceivers, and analog switch style functions. The family is useful when a board uses 3.3 V logic but still needs compatibility with 5 V-capable CMOS supply rails or legacy logic architecture.
SN74LV variants often appear in SOIC, SSOP, TSSOP, VQFN, PDIP, and other package formats, which makes them practical for both compact production hardware and boards that need easier inspection or rework. Compared with SN74LVC, SN74LV parts may trade some drive strength or speed depending on the function, while offering a useful supply range and established pinouts for common 74-series logic functions.
To choose an SN74LV device, identify the logic function, bit width, output-enable requirements, supply range, and package first. Then verify input thresholds, timing, output current, and whether the exact suffix supports the voltage and temperature range required. Octatronics groups the variants so buyers can compare sourcing options without mixing the family with HC, HCT, LVC, or AUP devices that may behave differently.

How to Choose the Right SN74LV Drivers, Receivers and Transceivers
Do not mix logic families casually
LV, LVC, HC, HCT, AHC, and AUP can have different input thresholds, speed, output drive, and supply limits.
Check analog switch limits
For LV switch functions, verify signal range, on-resistance, bandwidth, and supply configuration.
Confirm package migration
A function may exist in both PDIP and compact SMT packages, but board land pattern and thermal behavior still matter.
