Part Number : SN54HC244
Function : OCTAL BUFFERS AND LINE DRIVERS WITH 3-STATE OUTPUTS
Package : DIP, SOP 20 Pin Type
Maker : Texas Instruments
Pinouts : 
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 54HC244, SN54HC244 devices are organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OEis low, the device passes noninverted data from the A inputs to the Y outputs. When OEis high, the outputs are in the high-impedance state.
Features
1. Wide Operating Voltage Range of 2 V to 6 V
2. High-Current Outputs Drive Up to 15 LSTTL Loads
3. 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
4. Low Power Consumption: ICC, 80-µA (Maximum)
