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
