Product details

Buffer, 2V–5.5V, 3-State outputs, 20-TVSOP

Packaged in a compact 20-TFSOP (also designated 20-TVSOP), it suits space-constrained PCBs in industrial control, automotive body electronics, and telecom infrastructure where a glueless bus interface is needed.

The 2V to 5.5V supply range lets this buffer bridge 3.3V and 5V domains without a level translator, provided the input thresholds are compatible. Each output sources or sinks 8mA (symmetrical drive), which is sufficient for driving a few CMOS loads or a short trace but not a heavy bus — plan for fan-out accordingly. The 3-state outputs allow multiple buffers to share a data line when the output-enable controls are gated.

Housed in a 20-TFSOP (4.40mm width, 0.173" body) with a 0.5mm pin pitch, the footprint matches the industry-standard TSSOP-20 layout. The supplier device package is 20-TVSOP, which is electrically and mechanically identical to 20-TFSOP for this part. Surface-mount assembly is straightforward with standard reflow profiles.

ROHS3 compliant.
