Each of the four switches connects an A port to a B port with low on-resistance, effectively isolating or connecting two signal paths under a single enable control per pair. The 4.75V to 5.25V single-supply rail means this is a 5V-only part — not a 3.3V or dual-supply device, so check your logic levels before routing it into a lower-voltage bus. ## Two independent switch groups — what that means for routing The QS3244PAG contains two independent circuits, each with two 1:1 switches sharing a common enable. That gives you two separate enable domains on one 20-pin TSSOP. If your design needs to gate two different data buses independently — say, isolating a memory bank from a peripheral bus — this part handles it without an external inverter or a second device. The 20-TSSOP body (4.40 mm width) is a common footprint for signal-switching arrays, and the surface-mount package suits automated assembly lines. No special thermal management needed at the 5V supply — the switch's quiescent current is negligible.","metaTitle":"QS3244PAG Bus Switch, 4 x 1:1, 20-TSSOP, 5V Supply","metaDescription":"QS3244PAG bus switch from Renesas (IDT).
