General description
The 74ALVT162245 is a 16-bit transceiver with 30 Ω 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.

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 Ω making external termination resistors unnecessary • IOFF circuitry provides partial Power-down mode operation • 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
