SN74HCT244NSR Part Information
These octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clockdrivers, 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 noninverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.
- 3-State Outputs Drive Bus Lines and Buffer
- High-Current Outputs Drive up to 15 LSTTL Loads
- Inputs Are TTL-Voltage Compatible
- Low Input Current of 1 u00b5A Maximum
- Low Power Consumption: 80-u00b5A Maximum ICC
- Operating Voltage Range of 4.5 V to 5.5 V
- Typical tpd = 13 ns
- u00b16-mA Output Drive at 5 V
