74ALVT16601DL,512

Overview

The 74ALVT16601DL,512 is an 18-bit universal bus transceiver manufactured by Nexperia. It operates at VCC voltages of 2.3V to 2.7V or 3.0V to 3.6V with I/O compatibility up to 5V. The device features non-inverting 3-state outputs and bidirectional data flow controlled by OEAB, LEAB, CPAB, CEAB, OEBA, LEBA, CPBA, and CEBA inputs. It utilizes BiCMOS technology for high performance and low power dissipation.

Feature Summary

• Provides 18-bit bidirectional bus interface capability
• Features active bus hold circuitry to maintain valid logic levels on unused inputs
• Supports live insertion and extraction without bus current loading
• Includes positive-edge triggered clock inputs with latch-up protection

Applications

• High-performance bi-directional data transfer between buses
• Interface connections between systems operating at different supply voltages
• Memory buffer applications requiring latched data storage

Procurement Notes

Verify the component manufacturer as Nexperia due to business restructuring from NXP. Confirm the package type corresponds to SSOP56 (SOT371-1) and check the temperature range specification of -40 °C to +85 °C. Ensure compliance with RoHS directives and verify the specific ordering suffix matches the required packaging format.

Selection Notes

Select this component when an 18-bit wide bus interface is required with independent control over data direction and latching. It is suitable for designs needing 5V tolerant I/O while operating at lower core voltages. Consider the 3-state output capability and bus hold features for managing floating lines in complex system architectures.

Part Context

This part belongs to the 74ALVT series of advanced low-voltage TTL-compatible logic devices. It is a registered bus transceiver designed for high-speed data transmission. The DL variant specifically denotes the SSOP56 plastic shrink small outline package configuration.

Replacement Considerations

The 74ALVT16601DGG serves as a pin-compatible alternative utilizing the TSSOP56 package.
