Product data sheet
1. General description
The 74LVT244A; 74LVTH244A is a high-performance BiCMOS product designed for V_CC
operation at 3.3 V.
This device is an octal buffer that is ideal for driving bus lines. The device features two
output enables (1OE, 2OE), each controlling four of the 3-state outputs.
