MC14503B Hex Non-Inverting 3-State Buffer The MC14503B is a hex non−inverting buffer with 3−state outputs, and a high current source and sink capability.
The 3−state outputs make it useful in common bussing applications.
Two disable controls are provided.
A high level on the Disable A input causes the outputs of buffers 1 through 4 to go into a high impedance state and a high level on the Disable B input causes the outputs of buffers 5 and 6 to go into a high impedance state.
Features • 3−State Outputs • TTL Compatible − Will Drive One TTL Load Over Full Temperature Range • Supply Voltage Range = 3.
0 Vdc to 18 Vdc • Two Disable Controls for Added Versatility • Pin for Pin Replacement for MM...
