SN54HCT244 Datasheet | Texas Instruments

Features - Operating voltage range of 4.5V to 5.5V - High-current outputs drive up to 15 LSTTL loads - Low power consumption: 80µA maximum ICC - Typical tpd = 13ns - ±6m A output drive at 5V - Low input current of 1µA maximum - Inputs are TTL-voltage patible - 3-state outputs drive bus lines and buffer memory address registers 2 Applications - Servers - LED displays - Network switches - Tele infrastructure - Motor drivers - I/O expanders 1 1OE 3 Description These octal buffers and line 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. The SNx4HCT244 devices are organized as two 4-bit buffers or drivers with separate output-enable (OE) inputs. When OE is low, the device passes non inverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the highimpedance state.
