74ABT16244A 16-bit buffer/line driver 3-state Rev. 9 5 July 2021 Product data sheet 1. General description The 74ABT16244A 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. This device is fully specified for partial power down applications using I . The I circuitry disables the output, preventing the potentially OFF OFF damaging backflow current through the device when it is powered down. 2. Features and benefits Supply voltage range from 4.5 V to 5.5 V BiCMOS high speed and output drive Direct interface with TTL levels Power-up 3-state I circuitry provides partial Power-down mode operation OFF Latch-up protection exceeds 500 mA per JESD78B class II level A 16-bit bus interface Multiple V and GND pins minimize switching noise CC 3-state buffers Output capability: +64 mA and -32 mA Live insertion and extraction permitted ESD protection: HBM JESD22-A114F exceeds 2000 V CDM JESD22-C101-C exceeds 1000 V Specified from -40 C to +85 C 3.
