JESD8B/JESD36 (2.7 to 3.6 V)
• 3.6 V tolerant inputs/outputs
• CMOS low power consumption
• Direct interface with TTL levels (2.7 to 3.6 V)
• Power-down mode
• Latch-up performance exceeds 250 mA
• ESD protection:
HBM EIA/JESD22-A114-A exceeds 2000 V
MM EIA/JESD22-A115-A exceeds 200 V.
DESCRIPTION
The 74ALVC125 is a high-performance, low-power,
low-voltage, Si-gate CMOS device and superior to most
advanced CMOS compatible TTL families.
Schmitt-trigger action at all inputs makes the circuit
tolerant for slower input rise and fall times.
The 74ALVC125 consists of four non-inverting buffer/line
drivers with 3-state outputs. The 3-state outputs (nY) are
controlled by the output enable input (nOE). A HIGH on
pin nOE causes the outputs to assume a high-impedance
OFF-state.

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.
