October 1993
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 dis-
able input will cause those gates on its control line to go into
a high impedance state
