CD4503BC
Hex Non-In verting 3-STATE Buffer
General Description
The CD4503BC is a hex non- invert ing 3-S TATE buffer with
high output current sink and source capability. 3-STATE
outputs make it useful in bus-oriented applications. Two
separate disable inputs are provide d. Buffers 1 through 4
are controlled by the disable 4 inpu t. 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 lin e to go
into a high impedance state.
Features
■ Wide supply voltage range: 3.0 VDC to 18 V
DC
■ 3-STATE outputs
■ Symmetrical turn on/turn off delays
■ Symmetrical output rise and fall times
■ Pin-for-pin replacement for MM80C97 and MC14503
Ordering Code:
Devices also available in Tape and Reel. Specify by appending suffix letter “X” to the or dering code.

Note 1: “Absolute Maxi mum Ratings” are those valu es beyond which the
safety of the device cannot be guaranteed. They are not meant to imply
that the devices should be o perated at these lim its. The table s of “Recom mended Operating Conditions” and “Electrical Cha rac t eristics” provide conditions for actual device operation.
