1 Features 3 Description These SNx4ACT244 octal buffers and drivers are
designed specifically to improve the performance and
density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and transmitters. 1 4.5-V to 5.5-V VCC Operation
Inputs Accept Voltages to 5.5 V
Max tpd of 9.5 ns at 5 V
Inputs are TTL Compatible
On Products Compliant to MIL-PRF-38535,
All Parameters are Tested Unless Otherwise
Noted. On All Other Products, Production
Processing Does Not Necessarily Include Testing
of All Parameters. The SNx4ACT244 devices are organized as two 4-bit
buffers and drivers with separate output-enable (OE)
