Buffer, Non-Inverting 2 Element 4 Bit per Element 3-State Output 20-SSOP
DESCRIPTION The SN54LVCH244A octal buffer/line driver is designed for 2.7-V to 3.6-V VCC operation, and the SN74LVCH244A octal buffer/line driver is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVC244ADBR is an octal Buffer/Driver with 3-state outputs and designed for 1.65 to 3.6V VCC operation. This device is also designed for asynchronous communication between data buses. This device is organized as two 4-bit buffers/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. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver.
