74LVCH16T245ZQLR

Overview

The SN74LVCH16T245ZQLR is a 16-bit dual-supply bus transceiver manufactured by Texas Instruments. It features configurable voltage translation between Port A and Port B, supporting supply voltages from 1.65 V to 3.6 V on both ports. The device includes three-state outputs for bidirectional data transfer. It is housed in a 56-pin Microstar Junior (VFBGA) package with dimensions of 7 mm x 4.5 mm. The component operates within a temperature range of -40 °C to +85 °C.

Feature Summary

• Configurable voltage translation allows independent power supply rails for Port A and Port B
• Supports bidirectional data transfer via dual-supply architecture
• Provides three-state outputs for efficient bus management

Applications

• Voltage level translation between different logic families
• Bidirectional data bus interfaces in embedded systems
• High-density board-to-board connections requiring flexible voltage domains

Procurement Notes

Verify the specific suffix ZQLR against the manufacturer's current datasheet to confirm package type and pinout compatibility. Ensure that the required operating voltage ranges for both ports align with the system design specifications before integration.

Selection Notes

Select this component when designing systems requiring 16-bit wide buses with mixed voltage domains. The dual-supply capability eliminates the need for external level shifters, simplifying PCB layout and reducing component count compared to single-supply alternatives.

Part Context

This part belongs to the LVCH logic family, optimized for low-voltage applications. It serves as a high-performance alternative to standard LVC devices, offering improved switching speeds while maintaining compatibility with 3.3 V and lower voltage systems in portable and industrial electronics.
