DESCRIPTION

The 74LVX541 is a low voltage CMOS OCTAL BUS BUFFER with 3 STATE OUTPUT NON INVERTING fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power, battery operated and low noise 3.3V applications.

The 3 STATE control gate operates as two input AND such that if either G1 or G2 are high, all eight outputs are in the high impedance state.

In order to enhance PC board layout, the 74VHC541 offers a pinout having inputs and outputs on opposite sides of the package.

Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage.

This device can be used to interface 5V to 3V. It combines high speed performance with the true CMOS low power consumption.

All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
