SN74ALVCH16245DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH16245DLR is a 16-bit (dual-octal) noninverting bus transceiver designed for asynchronous communication between two data buses. It operates from a supply voltage of 1.65 V to 3.6 V and features 3-state outputs with a maximum propagation delay of 3 ns at 3.3 V. The device provides ±24 mA output drive capability and includes active bus-hold circuitry on data inputs, eliminating the need for external pullup or pulldown resistors. It offers ESD protection exceeding 2000 V via the human-body model and latch-up performance exceeding 250 mA per JESD 17. The component is housed in a 48-pin SSOP package.
