SN54ALS244C

SN54ALS244C, SN54AS244A, SN74ALS244C, SN74AS244A OCTAL BUFFERS AND LINE DRIVERS WITH 3-STATE OUTPUTS SDAS142C – JULY 1987 – REVISED AUGUST 1995 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers pnp Inputs Reduce dc Loading Package Options Include Plastic Small-Outline (DW) 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 the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. With the ′ALS240A, ′ALS241C, ′AS240A, and ′AS241A, these devices provide the choice of selected combinations of inverting outputs, symmetrical active-low output-enable (OE) inputs, and complementary OE and OE inputs. The -1 version of SN74ALS244C is identical to the standard version, except that the recommended maximum IOL for the -1 version is 48 mA. There is no -1 version of the SN54ALS244C. The SN54ALS244C and SN54AS244A are characterized for operation over the full military temperature range of – 55°C to 125°C. The SN74ALS244C and SN74AS244A are characterized for operation from 0°C to 70°C. 2Y1 GND 2A1 1Y4 2A2 SN54ALS244C, SN54AS244A . . . J PACKAGE SN74ALS244C, SN74AS244A . . .
