74ALVT162245 16-bit transceiver with 30 termination resistors 3-state Rev. 4 3 February 2021 Product data sheet 1. General description The 74ALVT162245 is a 16-bit transceiver with 30 termination resistors and 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. 2. Features and benefits 16-bit bidirectional bus interface 3-State buffers Wide supply voltage range from 2.3 to 3.6 V 5V I/O compatible Overvoltage tolerant inputs to 5.5 V Output capability: +12 mA/12 mA Direct interface with TTL levels Input and output interface capability to systems at 5 V supply BiCMOS high speed and output drive Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs Live insertion/extraction permitted Outputs include series resistance of 30 making external termination resistors unnecessary I circuitry provides partial Power-down mode operation OFF 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 ESD protection: MIL STD 883 method 3015: exceeds 2000 V MM: exceeds 200 V Specified from -40 C to +85 C 3.
