Philips Semiconductors
Quad buffer/line driver; 3-State
Product specification
74LVC125
FEATURES
Wide supply voltage range of 1.2 to 3.6 V
In accordance with JEDEC standard no. 8-1A
Inputs accept voltages up to 5.5 V
CMOS lower power consumption
Direct interface with TTL levels
Output drive capability 50 W transmission lines at 85°C
DESCRIPTION
The 74LVC125 is a high performance, low-power, low-voltage
Si-gate CMOS device and superior to most advanced CMOS
compatible TTL families.
The 74LVC125 consists of four non-inverting buffers/line drivers with
3-State outputs. The 3-State outputs (nY) are controlled by the
output enable input (nOE). A HIGH at nOE causes the outputs to
assume a high impedance OFF-state.

CPD
Power dissipation capacitance per buffer Notes 1 and 2
NOTES:
1. CPD is used to determine the dynamic power dissipation (PD in µW)
PD = CPD × VCC2 × fi +Σ (CL × VCC2 × fo) where:
fi = input frequency in MHz; CL = output load capacity in pF;
fo = output frequency in MHz; VCC = supply voltage in V;
Σ (CL × VCC2 × fo) = sum of the outputs.
2. The condition is VI = GND to VCC
