CD4503BM CD4503BC Hex Non-Inverting TRI-STATE Buffer
General Description
The CD4503B is a hex non-inverting TRI-STATE buffer with high output current sink and source capability TRI-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
