74VCX162601MTDX

Universal Bus Functions Overview

The onsemi 74VCX162601MTDX is an 18-bit universal bus transceiver housed in a 56-lead Thin Shrink Small Outline Package (TSSOP). It operates with a supply voltage range of 1.4V to 3.6V and features 3.6V tolerant inputs and outputs. The device integrates D-type latches and flip-flops for transparent, latched, and clocked data flow modes. B-port outputs include integrated 26Ω series resistors to reduce line noise. Maximum propagation delay from A to B is 3.8 ns at 3.0V to 3.6V VCC.

Universal Bus Functions FAQ

How does the device handle data flow direction?

Data flow is controlled by output-enable, latch-enable, and clock inputs, allowing for transparent, latched, or clocked modes in either direction.

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

The 26Ω series resistors are integrated into the B-port outputs to reduce line noise in applications such as memory address and clock drivers.
