1 / 6 page SN54HC240, SN74HC240 OCTAL BUFFERS AND LINE DRIVERS WITH 3-STATE OUTPUTS SCLS128B – DECEMBER 1982 – REVISED MAY 1997 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers D High-Current Outputs Drive up to 15 LSTTL Loads D Package Options Include Plastic (DW) and Ceramic Flat (W) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 300-mil DIPs description These octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The ’HC240 are organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the device passes inverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state. The SN54HC240 is characterized for operation over the full military temperature range of –55 °C to 125 °C. The SN74HC240 is characterized for operation from –40 °C to 85°C.
