Product specification

74LVC125

Quad buffer/line driver; 3-State

1997 Mar 18

853–1951 17865

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.

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
