Texas Instruments SN74ACT244
The SNx4ACT244 devices are organized as two 4bit buffers and drivers with separate output-enable (OE) inputs. When OE is low, the device passes noninverted data from the A inputs to the Y outputs.FEATURES
● 4.5-V to 5.5-V VCC operation● Inputs accept voltages to 5.5 V
● Maximum 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. 2
APPLICATIONS
● LED displays● Servers and telecommunication
● Switching networks 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. When OE is high, the outputs are in the highimpedance state.
