Product specification
74LVC541A
Octal buffer/line driver with 5-volt tolerant
inputs/outputs (3-State)
2
1998 Jul 29
853-2103 19803
FEATURES
5-volt tolerant inputs/outputs, for interfacing with 5-volt logic
Wide supply voltage range of 2.7V to 3.6V
Complies with JEDEC standard no. 8-1A
CMOS low power consumption
Direct interface with TTL levels
5 Volt tolerant inputs/outputs, for interfacing with 5 Volt logic
DESCRIPTION
The 74LVC541A is a high performance, low-power, low-voltage
Si-gate CMOS device and superior to most advanced CMOS
compatible TTL families.
Inputs can be driven from either 3.3V or 5.0V devices. In 3-State
operation, outputs can handle 5V. This feature allows the use of
these devices as translators in a mixed 3.3V/5V environment.
The 74LVC541A is an octal non-inverting buffer/line driver with
5-volt tolerant inputs/outputs. The 3-State outputs are controlled by
the output enable inputs OE1 and OE2.

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