These octal buffers/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. When these devices are used with the ?ALS241, ?AS241A, ?ALS244, and ?AS244A devices, the circuit designer has a choice of selected combinations of inverting and noninverting outputs, symmetrical active-low output-enable (OE)\ inputs, and complementary OE and OE\ inputs. These devices feature high fan-out and improved fan-in.

Features:
3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
PNP Inputs Reduce DC Loading
