Product specication
Quad buffer/line driver with 5 Volt tolerant input/outputs;
3-state
74LVC125A
FEATURES
5 V tolerant inputs/outputs for interfacing with 5 V logic
Wide supply voltage range from 1.2 to 3.6 V
CMOS low power consumption
Direct interface with TTL levels
Inputs accept voltages up to 5.5 V
Complies with JEDEC standard no. 8-1A
Specified from 40 to +85 °C and 40 to +125 °C.
DESCRIPTION
The 74LVC125A is a high-performance, low-power,
low-voltage, Si-gate CMOS device, superior to most
advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3 or 5 V devices.
In 3-state operation, outputs can handle 5 V.
The 74LVC125A consists of four non-inverting buffers/line
drivers with 3-state outputs (nY) which are controlled by
the output enable input (nOE). A HIGH at nOE causes the
outputs 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 + 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;
Σ(CL × VCC2 × fo) = sum of the outputs.
2. The condition is VI = GND to VCC.
