SN74ALVCH16245DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH16245DGGR 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 ±24-mA drive capability at 3.3 V. The device includes active bus-hold circuitry on data inputs, eliminating the need for external pullup or pulldown resistors. It provides ESD protection exceeding 2000 V via the human-body model and latch-up performance exceeding 250 mA per JESD 17. The maximum propagation delay is 3 ns at 3.3 V.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused inputs?

The SN74ALVCH16245DGGR utilizes active bus-hold circuitry to hold unused or undriven inputs at a valid logic state, which eliminates the need for external pullup or pulldown resistors.

What is the function of the DIR and OE inputs?

The Direction Control (DIR) input determines the direction of data flow between the A and B ports. The Output Enable (OE) input activates either the B-port or A-port outputs or places both into a high-impedance mode.
