74LVCH162245ADGG:1

Overview

The Nexperia 74LVCH162245ADGG:1 is a 16-bit bus transceiver housed in a TSSOP48 (SOT362-1) package. It operates within a supply voltage range of 1.2 V to 3.6 V and supports inputs up to 5.5 V. The device features integrated 30 Ω series termination resistors, Schmitt-trigger inputs, and IOFF circuitry for partial power-down protection. It includes bus hold functionality on all data inputs and provides two independent output enables and direction controls.

Feature Summary

• Integrated 30 Ohm series termination resistors for signal integrity
• Bus hold circuitry on all data inputs eliminates external pull-up requirements
• IOFF circuitry prevents damaging backflow current during partial power-down
• Overvoltage tolerant inputs accept signals up to 5.5 V

Applications

• Mixed 3.3 V and 5 V system translation
• Partial power-down applications requiring backflow prevention
• High-speed data bus interfacing with termination needs

Procurement Notes

Verify the specific ordering suffix ':1' corresponds to the required tape and reel or cut tape packaging configuration. Confirm that the TSSOP48 package variant matches the design footprint. Ensure the LVCH logic family meets the low-power and speed requirements for the target application environment.

Selection Notes

Select this component when 16-bit bi-directional translation between different voltage domains is required. The integrated termination resistors simplify PCB layout by reducing external component count. The bus hold feature ensures stable input states without additional hardware. Verify compatibility with the system's operating temperature range of -40 °C to +125 °C.

Part Context

This part belongs to the Nexperia 74LVCH162245A family of 16-bit bus transceivers. It shares functional similarities with the 74LVC162245A but utilizes Low-Voltage CMOS High-Speed technology for optimized power consumption. The ADGG suffix specifically denotes the TSSOP48 plastic thin shrink small outline package with a 6.1 mm body width.

Replacement Considerations

The 74LVC162245ADGG:1 is a compatible alternative within the same family offering identical pinout and functionality. Other variants such as the TVSOP48 version (74LVCH162245ADGV:1) provide the same electrical characteristics in a smaller footprint.
