74ALVCH16601DGG,11

Overview

The Nexperia 74ALVCH16601 is an 18-bit universal bus transceiver featuring 3-state outputs and bus hold inputs. It supports a wide supply voltage range from 1.65 V to 3.6 V, with recommended operating conditions of 2.3 V to 2.7 V for maximum speed at 30 pF load, or 3.0 V to 3.6 V at 50 pF load. The device operates within an ambient temperature range of -40 °C to +85 °C. It utilizes the MULTIBYTE flow-through standard pin-out architecture and includes low inductance multiple VCC and GND pins to minimize noise and ground bounce.

Feature Summary

• Universal data flow control via dedicated output enable, latch enable, clock enable, and clock inputs for both A-to-B and B-to-A directions.
• Bus hold circuitry on data inputs maintains signal integrity during idle states.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow current.
• Direct interface capability with TTL logic levels.

Applications

• High-density memory buffer applications
• Clock drivers and buffered oscillators
• Multiplexer demultiplexer and peer-to-peer bus architectures

FAQ

How does the IOFF feature function?

The IOFF circuitry disables the outputs when the device is powered down, preventing potentially damaging backflow current through the device.

What is the purpose of the bus hold inputs?

Bus hold inputs maintain the last known logic state of the data lines, ensuring stable signals when the bus is not actively driving data.
