Product details

Supply rail and logic-level compatibility

The 4.5V minimum supply means this buffer does not run from a 3.3V rail — it needs a regulated 5V supply. Input thresholds are 5V CMOS/TTL compatible; a 3.3V logic signal will not reliably cross the VIH(min) level at 5V VCC. If the design uses a mixed 3.3V/5V bus, a level-shifting buffer (such as the SN74LVTH series) is the correct choice. The 3-state output control (active-low output enable) lets multiple buffers share a common data bus without contention.

Package and footprint

The part comes in a 20-SSOP package — the narrow-body 5.3 mm wide variant with 0.65 mm pin pitch. This is a surface-mount package; no through-hole option exists for this order code. The shipping medium is Tape & Reel or Cut Tape, which suits both automated pick-and-place and small-quantity prototyping.

Lifecycle and sourcing posture

The part is ROHS3 compliant.

Frequently asked questions

Is SN74LV541ATDBR compatible with 3.3V input logic?

No. A 3.3V logic signal will not reliably meet the VIH(min) requirement at 5V VCC. For mixed-voltage buses, consider a 74LVTH or 74AVC series buffer.

What is the alternative for SN74LV541ATDBR if out of stock?

A functional alternative is the SN74LVTH16245ADGVR from the 74LVTH series. It is a 16-bit transceiver (two 8-bit elements) with 32 mA output drive, 3-state outputs, and a wider 2.7V to 3.6V supply range. Note the supply voltage difference — the LVTH part is 3.3V native, not 5V. Verify the supply rail and bit width before substituting.
