DESCRIPTION
The 74LVC1G126 is a high-performance, low-power,
low-voltage, Si-gate CMOS device, superior to most
advanced CMOS compatible TTL families.
The input can be driven from either 3.3 or 5 V devices.
This feature allows the use of this device in a mixed
3.3 and 5 V environment.
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 HIGH level at pin OE
causes the output to assume a high-impedance
OFF-state.
QUICK REFERENCE DATA
GND = 0 V; Tamb =25 °C; tr =tf ≤ 2.5 ns.
Notes
1. CPD is used to determine the dynamic power dissipation (PD in W).
PD =CPD × VCC2 × fi +(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.
2. The condition is VI = GND to VCC.
