Strobed hex inverter/buffer
DESCRIPTION
The HEF4502B consists of six inverter/buffers with 3-state
outputs. When the output enable input (EO) is HIGH all six
outputs (O1 to O6) are in the high impedance OFF-state.
When the enable input (E) is HIGH all six outputs are
switched to LOW. The outputs have a 2-TTL load drive
capability.
