74HCT126PW,112

Overview

The Nexperia 74HCT126PW,112 is a quad buffer and line driver featuring three-state outputs controlled by active HIGH enable inputs (nOE). It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL input levels. The device provides four non-inverting buffers with high-impedance OFF-states when disabled. It complies with JEDEC standards JESD7A and includes ESD protection exceeding 2000 V HBM and 1000 V CDM. The component is specified for ambient temperatures from -40 °C to +125 °C and utilizes a TSSOP14 package.
