SN74ACT244 Datasheet | Texas Instruments

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 patible - On products pliant 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 telemunication - 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. 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. When OE is high, the outputs are in the highimpedance state.
