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 VCC.
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
