74LVT162244B 3.3 V 16-bit buffer/driver with 30 termination resistors 3-state Rev. 5 6 August 2021 Product data sheet 1. General description The 74LVT16244B is a 16-bit buffer/line driver with 3-state outputs. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The device features four output enables (1OE, 2OE, 3OE and 4OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs 2. Features and benefits 16-bit bus interface 3-state buffers Outputs include series resistance of 30 making external termination resistors unnecessary Output capability: +12 mA/12 mA Wide supply voltage range from 2.7 to 3.6 V BiCMOS high speed and output drive Direct interface with TTL levels Overvoltage tolerant inputs to 5.5 V Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs Live insertion/extraction permitted Power-up 3-state No bus current loading when output is tied to 5 V bus I circuitry provides partial Power-down mode operation OFF Latch-up performance exceeds 500 mA per JESD 78 Class II Level B Complies with JEDEC standard JESD8C (2.7 V to 3.6 V) ESD protection: HBM: JESD22-A114F exceeds 2000 V MM: JESD22-A115-A exceeds 200 V Specified from -40 C to 85 C 3.
