Product overview
Overview
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 MM80C97 and 340097
• Pb−Free Packages are Available
