74ALVC164245DLG4

Overview

The SN74ALVC164245DLG4 is a 16-bit dual-supply bus transceiver designed for asynchronous communication between data buses. It features two independent power rails: Port A (VCCA) operates at 2.5 V or 3.3 V, while Port B (VCCB) supports 3.3 V or 5 V. This architecture enables level shifting between 2.5 V and 3.3 V environments, or between 3.3 V and 5 V systems. The device provides three-state outputs and is housed in a 48-pin SSOP package. It supports bidirectional data flow controlled by direction inputs.

Feature Summary

• Dual-supply architecture allowing flexible voltage translation between 2.5 V, 3.3 V, and 5 V domains
• High-speed data transmission capability with propagation delays as low as 2.4 ns
• Strong output drive strength of ±24 mA at 3.3 V operation
• Compliance with JESD-17 standard for latch-up performance exceeding 250 mA

Applications

• Electronic point-of-sale (EPOS) systems
• Printers and other peripheral devices
• Motor driver interfaces
• Wireless and telecommunications infrastructure
• Wearable health and fitness equipment

Procurement Notes

Verify the specific suffix 'G4' to confirm lead-free and RoHS compliance status as per Texas Instruments documentation. Ensure the SSOP-48 package dimensions match the target PCB footprint requirements. Confirm that the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the intended application design.

Selection Notes

Select this component when interfacing logic families requiring translation between 2.5 V/3.3 V and 3.3 V/5 V supply voltages. The ALVC series offers lower power consumption compared to older LVC technologies. Ensure the system design accommodates the separate VCCA and VCCB power supplies to utilize the full level-shifting functionality effectively.

Part Context

This part belongs to the SN74ALVC164245 family of widebus transceivers from Texas Instruments. It is functionally similar to the SN74ALVC164245 but distinguished by its specific 48-lead SSOP packaging variant. The device serves as a bridge for high-density data buses in mixed-voltage digital systems.

Replacement Considerations

Direct pin-compatible substitutes include the SN74ALVC164245DGGT and SN74ALVC164245DGGR. Verify that alternative packages maintain identical electrical characteristics and pinout configurations before implementation.
