Product details

Output drive and signal integrity

With a symmetrical 32 mA output drive capability, this buffer can directly drive the input capacitance of several downstream logic gates or a low-power LED indicator without an external transistor. The push-pull output eliminates the need for a pull-up resistor, simplifying board layout and reducing component count in signal-buffering stages. Because the 74LVC family is specified with 5 V tolerant inputs even when powered at 1.65 V, the SN74LVC1G34DRLR can interface between a low-voltage core and a legacy 5 V peripheral without a level shifter.

SOT-553 footprint and supply posture

Housed in the 5-pin SOT-553 package (supplier device package SOT-5), the part occupies a board area of roughly 1.6 mm × 1.6 mm, suiting space-constrained portable or sensor-module designs.

Frequently asked questions

What is the closest functional alternative to SN74LVC1G34DRLR?

The SN74LVC1G125YZPR is a single non-inverting buffer from the same 74LVC family with the same 32 mA output drive and supply range, but its output is 3-state rather than push-pull. The SN74LVC1G34DRLR's push-pull output means it does not require an external pull-up resistor; the 1G125 version needs one when the output is enabled.
