74ALVC162601TX

Overview

The onsemi 74ALVC162601TX is an 18-bit universal bus transceiver designed for low-voltage applications. It operates within a supply voltage range of 1.65V to 3.6V and features inputs and outputs tolerant up to 3.6V. The device integrates D-type latches and flip-flops, enabling transparent, latched, and clocked data flow modes controlled by dedicated enable and clock inputs. It includes 26Ω series resistors in the B-port outputs to reduce line noise. Packaged in a 56-lead Thin Shrink Small Outline Package (TSSOP), it supports live insertion and utilizes patented noise reduction circuitry.

The component serves as a versatile interface solution for digital systems requiring robust signal integrity and multi-mode data handling capabilities.

Replacement Considerations

Check datasheets for alternative 18-bit bus transceivers with similar voltage tolerances and pin configurations. Verify functional equivalence regarding latch/flip-flop modes and output drive characteristics before substitution.

FAQ

How does the device handle data flow direction?

Data flow in each direction is controlled by separate output-enable, latch-enable, and clock inputs, allowing independent configuration for A-to-B and B-to-A transmission.

What is the purpose of the series resistors in the B-port?

The 26Ω series resistors in the B-port outputs are designed to reduce line noise and electromagnetic interference in high-speed applications.
