Product details

The SN74CB3Q3244PWR is a 4-bit bus switch from the 74CB series, configured as two independent 4 x 1:1 circuits. The switch connects a single input to a single output per channel with low on-resistance, allowing signal pass-through without adding propagation delay. The 4 x 1:1 topology means each of the four channels is a simple SPST switch — no address decoding or bus arbitration logic is needed.

Housed in a 20-TSSOP (0.173", 4.40 mm width) surface-mount package, the SN74CB3Q3244PWR fits standard 0.65 mm pitch layouts. The supplier device package is also 20-TSSOP, so no footprint variation between the generic and TI-specific designators.

Active production, ROHS3 compliant

No end-of-life notice or successor part is recorded — the part continues as a standard catalog item.
