74VCXR162601MTX

Universal Bus Functions Overview

The onsemi 74VCXR162601MTX 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 inputs and outputs tolerant up to 3.6V. The device integrates D-type latches and flip-flops, allowing data flow in transparent, latched, and clocked modes controlled by OE, LE, CLK, and CLKEN inputs. It includes 26Ω series resistors on both A and B port outputs to reduce line noise. Propagation delay is a maximum of 3.8ns at 3.0V to 3.6V VCC.
