MC14503BCP (Hex Non-Inverting 3-StateBuffer) Motorola

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.

•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
