The document describes the DM54251/DM74251 Tri-State Data Selectors/Multiplexers, which contain full on-chip binary decoding to select one-of-eight data sources. These devices feature a strobe-controlled TRI-STATE output that permits direct connection to a common bus and can perform parallel-to-serial conversion.
| Typical propagation delay time (D to Y) | 17ns |
|---|---|
| Typical power dissipation | 155 mW |
| Storage Temperature Range | -65°C to +180°C |
The strobe must be at a low logic level to enable these devices; when high, outputs are in a high-impedance state.
The maximum supply voltage is 5.5V.
