74ALVC16245 74ALVCH16245 16-bit transceiver with direction pin 3-state Rev. 6 5 August 2021 Product data sheet 1. General description The 74ALVC16245 74ALVCH16245 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 OFF OFF the output, preventing the potentially damaging backflow current through the device when it is powered down. The 74ALVCH16245 has an active bushold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors. 2. Features and benefits Wide supply voltage range from 1.2 V to 3.6 V CMOS low power consumption MULTIBYTE flow-through standard pin-out architecture Low inductance multiple V and GND pins for minimize noise and ground bounce CC Overvoltage tolerant inputs to 5.5 V Direct interface with TTL levels I circuitry provides partial Power-down mode operation OFF All data inputs have bushold (74ALVCH16245 only) Latch-up performance exceeds 100 mA per JESD 78 Class II Level B Output drive capability 50 transmission lines at 85 C Current drive 24 mA at V = 3.0 V. CC Complies with JEDEC standards: JESD8-5 (2.3 V to 2.7 V) JESD8B/JESD36 (2.7 V to 3.6 V) ESD protection: HBM ANSI/ESDA/JEDEC JS-001 exceeds 2000 V CDM JESD22-C101E exceeds 1000 V 3.
