The 3-state control allows multiple outputs to share a line without contention. ## Package and footprint — 14-SSOP surface mount The SSOP footprint is smaller than a standard SOIC, so verify the land pattern matches your PCB layout — it is not pin-compatible with SOIC-14 without a pad adjustment. This makes it suitable for new designs requiring a standard 74LS logic buffer in a commercial temperature range.","metaTitle":"SN74LS125ADBR 74LS Buffer, Non-Inverting, 3-State, 14-SSOP","metaDescription":"Texas Instruments SN74LS125ADBR 74LS quad buffer with 3-state outputs, 4.75V-5.25V supply, commercial temp 0°C-70°C, 14-SSOP.

A pin-compatible alternative would be any other 74LS125 variant in the same 14-SSOP package, such as the SN74LS125AD (SOIC-14) — but note the package difference.
