The 1 x 1:1 topology means no address decoding — the single switch is enabled by the output-enable pin (active low, per the 74CB family convention). ## Package and board integration The SOT-23-5 (SC-74A) footprint is a standard small-outline transistor package with 1.27 mm pitch — easy to route on two-layer boards. The supplier device package is SOT-23-5, identical to the SC-74A; no footprint mismatch. ROHS3 compliant, so it meets the latest EU restriction directive without exemption. No official second-source or pin-compatible alternative is documented by TI; the part is single-sourced from TI.","metaTitle":"SN74CB3T1G125DBVR Bus Switch, 1 x 1:1, SOT-23-5, TI","metaDescription":"Texas Instruments SN74CB3T1G125DBVR bus switch, 1 x 1:1 circuit, 2.3V-3.6V supply, SOT-23-5.
