The 74LVCH16541A 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 74LVCH16541A is a 16-bit inverting buffer/line driver with

To ensure the high impedance state during power up or power
down, OE should be tied to V through a pullup resistor; the

minimum value of the resistor is determined by the current-sinking
capability of the driver.

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 performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output voltage ratings may be exceeded if the input and output clamp current ratings are observed.
