Philips Semiconductors
Octal buffer/line driver with 5-volt tolerant
inputs/outputs (3-State)
Product specification
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.
