00 — Overview

What the NL17SZ125 does

The NL17SZ125 is a high performance non-inverting 3-state buffer operating from a 1.65 V to 5.5 V supply. It features extremely high speed with a typical propagation delay of 2.6 ns at 5.0 V. The device supports overvoltage tolerant inputs and outputs, providing 24 mA balanced output sink and source capability. It maintains near zero static supply current to reduce system power requirements. The 3-state OE input is active-low, allowing multiple devices to share a single bus line. This buffer is compatible with LVTTL and LVCMOS logic standards. It serves as a direct replacement for the NC7SZ125. Available in various packages including SOT-353, TSOP-5, and UDFN6, it handles storage temperatures from -65 to +150 °C.
