The CD4503BCN is a hex non-inverting 3-State buffer with high output current sink and source capability. 3-State outputs make it useful in bus-oriented applications. Two separate disable inputs are provided. Buffers 1 through 4 are controlled by the disable 4 input. Buffers 5 and 6 are controlled by the disable 2 input. A high level on either disable input will cause those gates on its control line to go into a high impedance state.
Wide supply voltage range: 3.0 VDC to 18 VDC
Symmetrical turn on/turn off delays
Symmetrical output rise and fall times
Pin-for-pin replacement for MM80C97 and MC14503
