CD4503BMCD4503BC 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
