The 74LVT244A; 74LVTH244A is a high-performance BiCMOS product designed for VCC operation at 3.3 V. This device is an octal buffer that is ideal for driving bus lines. The device features two output enables, each controlling four of the 3-state outputs.
Octal bus interface
Output capability: +64 mA and -32 mA
TTL input and output switching levels
Input and output interface capability to systems at 5 V supply
Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs
Live insertion and extraction permitted
No bus current loading when output is tied to 5 V bus
