Octal buffer/line driver with 5-volt tolerant inputs/outputs (3-State)
74LVC241A
FEATURES
* 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 * High impedance when VCC = 0 V
DESCRIPTION
The 74LVC241A 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 3.3 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.

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.
