FEATURES
DESCRIPTION
The 74LVC241A is a high-performance, low-power, low-voltage,
Si-gate CMOS device and superior to most advanced CMOS
compatible TTL families.
• 5-Volt tolerant inputs/outputs, for interfacing with 5-volt logic.
• Supply voltage range of 1.2 to 3.6 V
• In accordance with JEDEC standard no. 8-1A
• CMOS lower power consumption
• Direct interface with TTL levels
Inputs can be driven from either 3.3 V or 5 V devices. In 3-State
operation, outputs can handle 5 V. This feature allows the use of
these devices as translators in a mixed 3.3 V/5 V environment.
The 74LVC241A is an octal non-inverting buffer/line driver with 3-State
outputs. The 3-State outputs are controlled by the output enable inputs
1OE and 2OE. Schmitt-trigger action at all inputs makes the circuit
highly tolerant for slower input rise and fall times.
• High impedance when V = 0 V

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
