This device is organized as two 4-bit line drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state. The LVCH244A has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance. 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. Inputs can be driven from either 3.3V or 5V devices. This feature allows theuseofthisdeviceasatranslatorinamixed3.3V/5Vsystemenvironment. The LVCH244A has “bus-hold” which retains the inputs’ last state whenever the input goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors. 1 A1 1 A2 1 A3 1 A4 1 Y1 1 Y2 1 Y3 1 Y4 2 A1 2 A2 2 A3 2 A4 2 Y1 2 OE 2 Y2 2 Y3 2 Y4 19 11 9 15 5 7 13 3 17 1 2 4 6 8 18 16 14 12 1 OE |
