74LVT2244 3.3 V octal buffer/line driver with 30 termination resistors 3-state Rev. 4 17 May 2021 Product data sheet 1. General description The 74LVT2244 is an 8-bit buffer/line driver with 3-state outputs. The device can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE), 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 The 74LVT2244 is designed with 30 series resistance in both the HIGH and LOW states of the output. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus receivers/transmitters. 2. Features and benefits Octal bus interface 3-state buffers Wide supply voltage range from 2.7 to 3.6 V Overvoltage tolerant inputs to 5.5 V BiCMOS high speed and output drive Output capability: +12 mA and -12 mA Direct interface with TTL levels No bus current loading when output is tied to 5 V bus Bus hold on data inputs Power-up 3-state I circuitry provides partial Power-down mode operation OFF Live insertion and extraction permitted Latch-up performance exceeds 500 mA per JESD 78 Class II Level B ESD protection: HBM JESD22-A114E exceeds 2000 V MM JESD22-A115-A exceeds 200 V 3.
