16-bit transceiver with 30 Ω termination resistors; 3-state

Rev. 4 — 3 February 2021

Product data sheet

1. 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.

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 Ω making external termination resistors unnecessary

I_OFFcircuitry 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
