74LVT16652ADGG,118

Overview

The 74LVT16652ADGG,118 is a high-performance BiCMOS 3.3 V 16-bit bus transceiver and register featuring 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V and supports TTL input/output switching levels. The device provides an output capability of +64 mA and -32 mA. Propagation delays are specified at 2.1 ns typical for nAx to nBx transitions at 3.3 V. It includes complementary output enable inputs and select controls for real-time or stored data transfer.

Feature Summary

• Configurable as two 8-bit transceivers or one 16-bit transceiver with independent control
• Bus-hold data inputs eliminate the need for external pull-up resistors on unused inputs
• Supports live insertion and extraction without bus current loading when tied to a 5 V bus
• Power-up reset and power-up 3-state functionality ensure safe initialization

Applications

• High-speed 16-bit bus interface systems
• Memory buffer applications requiring registered data storage
• Systems requiring simultaneous real-time and stored data transfer modes
• Interfaces between 3.3 V logic and 5 V tolerant systems

Procurement Notes

Verify component authenticity through authorized Nexperia distributors. Confirm package integrity for TSSOP-56 (SOT364-1). Check datasheet revision status for latest electrical characteristics. Ensure ESD handling protocols are followed during assembly. Validate operating temperature range compliance for industrial applications.

Selection Notes

Select this component for designs requiring dual 8-bit or single 16-bit bidirectional data flow with internal latching capabilities. Suitable for interfaces needing 5 V tolerance on I/O pins while operating at 3.3 V. Consider the TSSOP-56 package constraints for PCB layout. Evaluate propagation delay requirements against system clock speeds.

Part Context

This part belongs to the 74LVT series of low-voltage CMOS logic devices originally developed by Philips Semiconductors, now manufactured by Nexperia. The 'A' suffix typically denotes improved specifications or revisions within the family. The 'DGG' indicates the TSSOP-56 plastic thin shrink small outline package variant.
