The CD4503BC is a hex non-inverting 3-STATE buffer withhigh output current sink and source capability. 3-STATEoutputs make it useful in bus-oriented applications. Twoseparate disable inputs are provided. Buffers 1 through 4are controlled by the disable 4 input. Buffers 5 and 6 arecontrolled by the disable 2 input. A high level on either disableinput will cause those gates on its control line to gointo a high impedance state.Features Wide supply voltage range: 3.0 VDC to 18 VDC3-STATE outputsSymmetrical turn on/turn off delaysSymmetrical output rise and fall timesPin-for-pin replacement for MM80C97 and MC14503
