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 V_DC to 18 V_DC
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
