DM7810 - quad 2-input TTL-MOS interface gate
These Series 54/74 compatible gates are high output voltage versions of the DM5401/DM7401 (SN 5401 /SN 740 1), DM5403/DM7403 (SN 5403/SN 7403), and DM5405/DM7405 (SN5405/SN7405).
Their open-collector outputs may be "pulled-up" to +14 volts in the logical "1" state thus providing guaranteed mteFface
