SN74HCT244DWR 3-State Octal Buffer/Line Driver with HCT Speed LSTTL Compatibility High-Current Outputs Wide Operating Voltage and Balanced Propagation Delays

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

• ±6mA output drive at 5V

• Low input current of 1µA maximum

• Inputs are TTL-voltage compatible

• 3-state outputs drive bus lines and buffer memory address registers

Applications

• Servers

• LED displays

• Network switches

• Telecom infrastructure

• Motor drivers

• I/O expanders

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 high impedance state.
