FEATURES
DESCRIPTION
• Wide supply voltage range from 1.65 V to 5.5 V
• High noise immunity
The 74LVC1G126 is a high-performance, low-power,
low-voltage, Si-gate CMOS device, superior to most
advanced CMOS compatible TTL families.
• Complies with JEDEC standard:
– JESD8-7 (1.65 V to 1.95 V)
The input can be driven from either 3.3 V or 5 V devices.
This feature allows the use of this device in a mixed
3.3 V and 5 V environment.
– JESD8-5 (2.3 V to 2.7 V)
– JESD8B/JESD36 (2.7 V to 3.6 V).
• ±24 mA output drive (VCC = 3.0 V)
• CMOS low power consumption
• Latch-up performance exceeds 250 mA
• Direct interface with TTL levels
• Inputs accept voltages up to 5 V
• Multiple package options
This device is fully specified for partial power-down
applications using Ioff. The Ioff circuitry disables the output,
preventing the damaging backflow current through the
device when it is powered down.
The 74LVC1G126 provides one non-inverting buffer/line
driver with 3-state output. The 3-state output is controlled
by the output enable input (OE). A low level at pin OE
causes the output to assume a high-impedance
OFF-state.
• ESD protection:
– HBM EIA/JESD22-A114-B exceeds 2000 V
– MM EIA/JESD22-A115-A exceeds 200 V.
• Specified from −40 °C to +85 °C and −40 °C to +125 °C.

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. The condition is VI = GND to VCC
.
