The 74HC2G126; 74HCT2G126 is a dual buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE). Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
The document describes the NXP 74HC2G126 and 74HCT2G126 as a dual buffer/line driver featuring 3-state outputs controlled by output enable inputs. These devices include clamp diodes on inputs, allowing for current limiting resistors to interface with voltages exceeding VCC.
Key features include wide operating voltage ranges (2.0V to 6.0V), symmetrical output impedance, high noise immunity, and low power dissipation. The datasheet provides comprehensive ordering information for various packages such as TSSOP8, VSSOP8, and XSON8, along with detailed static and dynamic characteristics tables.
