74ALVC16501MTD

Overview

The onsemi 74ALVC16501MTD is an 18-bit universal bus transceiver combining D-type latches and flip-flops for transparent, latched, and clocked data flow. It operates with a supply voltage of 1.65V to 3.6V and features 3.6V tolerant inputs and outputs. Propagation delay ranges from 3.4 ns max at 3.0V–3.6V to 7.0 ns max at 1.65V–1.95V. The device supports live insertion/withdrawal and utilizes patented noise/EMI reduction circuitry. It is housed in a 56-lead Thin Shrink Small Outline Package (TSSOP).

Feature Summary
