74HC2G126; 74HCT2G126 Dual buffer/line driver; 3-state Rev. 5 18 December 2013 Product data sheet 1. General description 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 V . CC 2. Features and benefits Wide operating voltage from 2.0 V to 6.0 V Input levels: For 74HC2G126: CMOS level For 74HCT2G126: TTL level Complies with JEDEC standard no. 7A Symmetrical output impedance High noise immunity Low power dissipation Balanced propagation delays ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V Multiple package options Specified from 40 C to +85 C and 40 C to +125 C 3.
