DESCRIPTION

The U74HC540 combines with octal buffers and line drivers with

inverting 3-state outputs. The 3-state output is controlled by output

enable inputs OE1 and OE2 , all eight outputs will be in

high-impedance when either of the 2 inputs is applied with high

voltage.



FEATURES

* Operation voltage range: 2V ~ 6V

* High-current 3-state outputs for bus driver

* Inverting outputs
