Product speciﬁcation

Dual buffer/line driver; 3-state

74HC2G126; 74HCT2G126

FEATURES

• Wide operating voltage from 2.0 to 6.0 V

• Symmetrical output impedance

• High noise immunity

• Low power dissipation

• Balanced propagation delays

• Very small 8 pins package

• Output capability: bus driver

• ESD protection:

– HBM EIA/JESD22-A114-A exceeds 2000 V

• Specified from −40 to +85 °C and −40 to +125 °C.

DESCRIPTION

The 74HC2G/HCT2G126 is a high-speed Si-gate CMOS

device.

The 74HC2G/HCT2G126 provides one non-inverting

buffer/line driver with 3-state output. The 3-state output is

controlled by the output enable input pin (OE). A LOW at

pin OE causes the output as assume a high-impedance

OFF-state.

The bus driver output currents are equal compared to the

74HC/HCT126.

QUICK REFERENCE DATA

GND = 0 V; Tamb =25 °C; tr =rf ≤ 6.0 ns.

Notes

1. CPD is used to determine the dynamic power dissipation (PD in µW).

PD =CPD × VCC2 × fi × N+ Σ(CL × VCC2 × fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

CL = output load capacitance in pF;

VCC = supply voltage in Volts;

N = total switching outputs;

Σ(CL × VCC2 × fo) = sum of the outputs.

2. For the 74HC2G126 the condition is VI = GND to VCC.

For the 74HCT2G126 the condition is VI = GND to VCC − 1.5 V.
