FEATURES
5 volt tolerant inputs/outputs for interfacing with 5V logic
Wide supply voltage range of 1.2V to 3.6V
Complies with JEDEC standard no. 8-1A
CMOS low power consumption
MULTIBYTE
TM
flow-through standard pin-out architecture
Low inductance multiple power and ground pins for minimum
noise and ground bounce
Direct interface with TTL levels
DESCRIPTION
The 74LVC16241A is a high-performance, low-power, low-voltage,
Si-gate CMOS device, superior to most advanced CMOS
compatible TTL families. Inputs can be driven from either 3.3V or 5V
devices. In 3-State operation, outputs can handle 5V. These
features allow the use of these devices in a mixed 3.3V/5V
environment.
The 74LVC16241A is a 16-bit buffer/line driver with 3-State outputs.
The 3-State outputs are controlled by the output enable inputs nOE
and nOE. Schmitt-trigger action at all inputs makes the circuit highly
tolerant for slower input rise and fall times. The device can be used
as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer.

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 clamp current ratings are observed.
