74LVT244A 74LVTH244A 3.3 V octal buffer/line driver 3-state Rev. 7 17 August 2021 Product data sheet 1. General description The 74LVT244A 74LVTH244A 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 2. Features and benefits Octal bus interface 3-state buffers Output capability: +64 mA and -32 mA Wide supply voltage range from 2.7 to 3.6 V Overvoltage tolerant inputs to 5.5 V Direct interface with TTL levels BiCMOS high speed and output drive I circuitry provides partial Power-down mode operation OFF Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs Live insertion and extraction permitted Power-up 3-state No bus current loading when output is tied to 5 V bus 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-A114E exceeds 2000 V MM JESD22-A115-A exceeds 200 V Specified from -40 C to 85 C 3.
