CD4503BC

Hex Non-Inverting 3-STATE Buffer

General Description

The CD4503BC 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 dis-

able input will cause those gates on its control line to go

into a high impedance state.

Features

s Wide supply voltage range: 3.0 VDC to 18 VDC

s 3-STATE outputs

s Symmetrical turn on/turn off delays

s Symmetrical output rise and fall times

s Pin-for-pin replacement for MM80C97 and MC14503

Note 1: “Absolute Maximum Ratings” are those values beyond which the

safety of the device cannot be guaranteed. They are not meant to imply

that the devices should be operated at these limits. The tables of “Recom-

mended Operating Conditions” and “Electrical Characteristics” provide con-

ditions for actual device operation.
