These octal buffers/drivers are designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The designer has a choice of selected combinations of inverting and noninverting outputs, symmetrical active-low output-enable (OE) inputs, and complementary OE and OE inpu.
SN54ALS241C and SN54AS241A are characterized for operation over the full military temperature range of − 55°C to 125°C. The SN74ALS241C and SN74AS241A are characterized for operation from 0°C to 70°C. 2Y1 GND 2A1 1Y4 2A2 SN54ALS241C, SN54AS241A . . . J PACKAGE SN74ALS241C, SN74AS241A . . .
