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

ten is the same as tPZL and tPZH.
tdis is the same as tPLZ and tPHZ.
tt is the same as tTHL and tTLH.
[3] CPD is used to determine the dynamic power dissipation (PD in W).
PD = CPD VCC2 fi N + (CL VCC2 fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
(CL VCC2 fo) = sum of outputs.
