HEF4502B is Strobed hex inverter/buffer manufactured by NXP Semiconductors.
| Part Number | Description |
|---|---|
| HEF4505B | 64-bit/ 1-bit per word random access read/write memory |
| HEF4508B | Dual 4-bit latch |
| HEF4510B | BCD up/down counter |
| HEF4511B | BCD to 7-segment latch/decoder/driver |
| HEF4512B | 8-input multiplexer with 3-state output |
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.
