Drive for Dialight 745-0005 64-character alphamerle display generates desired character in response to pattern of 0s and 1s on input lines A1-A6. Timing of sequential scanning operation for seven horizontal rows of matrix is controlled by clock that drives binary counter having row-selecting outputs A, B, and C. Outputs C1-C5 of ROM correspond to vertical rows of dots enabled by 1-out-of-8 decoder．－"Readout Displays,"Dialight,Brooklyn, NY,1978,Catalog SG745,p 24－26.
These TTL hex inverter buffers/drivers feature high-voltage open-collector outputs for interfacing with high-level circuits (such as MOS) or for driving high-current loads (such as lamps or relays), and also are characterized for use as inverter buffers for driving TTL inputs. The
SN5406 and SN7406 have minimum breakdown voltages of 30 V. The SN5416 and SN7416 have minimum breakdown voltages of 15 V. The maximum sink current is 30 mA for the SN5406 and SN5416, and 40 mA for the SN7406 and SN7416.
