Introduction
These octal buffers and line 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 ’AC244 devices are organized as two 4 - bit buffers/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. To ensure the high - impedance state during power up or power down, OE should be tied to Vcc through a pullup resistor; the minimum value of the resistor is determined by the current - sinking capability of the driver.
Features
- 2 - V to 6 - V Vcc Operation
- Inputs Accept Voltages to 6 V
- Max tpd of 7.5 ns at 5 V
Applications
- Three-state memory address driver
- Clock driver
- Bus-oriented receiver
- Bus-oriented transmitter
