74ABT16245B 16-bit bus transceiver 3-state Rev. 6 14 July 2021 Product data sheet 1. General description The 74ABT16245B is a 16-bit transceiver with 3-state outputs. The device can be used as two 8-bit transceivers or one 16-bit transceiver. The device features two output enables (1OE and 2OE) each controlling eight outputs, and two send/receive (1DIR and 2DIR) inputs for direction control. 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, OFF OFF preventing the potentially damaging backflow current through the device when it is powered down. 2. Features and benefits Supply voltage range from 4.5 to 5.5 V BiCMOS high speed and output drive Direct interface with TTL levels 16-bit bidirectional bus interface Multiple V and GND pins minimize switching noise CC Power-up 3-state 3-state buffers Output capability: +64 mA and -32 mA Live insertion/extraction permitted I circuitry provides partial Power-down mode operation OFF Latch-up performance exceeds 500 mA per JESD 78 Class II Level B ESD protection: HBM JESD22-A114E exceeds 2000 V CDM JESD22-C101C exceeds 1000 V Specified from -40 C to 85 C 3.
