74LVCH162245ADGG,5

Overview

The Nexperia 74LVCH162245ADGG is a 16-bit bus transceiver housed in a TSSOP48 package (SOT362-1). It operates within a supply voltage range of 1.2 V to 3.6 V and features 3-state outputs with integrated 30 Ω series termination resistors. The device supports bidirectional data transfer controlled by two direction inputs (1DIR, 2DIR) and two output enables (1OE, 2OE). Inputs are overvoltage tolerant up to 5.5 V, allowing direct interfacing with 3.3 V or 5 V logic systems. Propagation delay ranges from 1.0 ns to 9.5 ns depending on voltage and temperature.

Feature Summary

• Integrated 30 Ohm series termination resistors for signal integrity
• Bus hold circuitry on all data inputs to eliminate external pull-up requirements
• IOFF circuitry enabling partial power-down mode operation
• Overvoltage tolerant inputs compatible with 5.5 V signals

Applications

• Mixed 3.3 V and 5 V system environments
• Partial power-down applications requiring backflow current prevention
• High-speed data buses utilizing standard multibyte flow-through architecture

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature rating. Confirm that the requested variant matches the required JEDEC compliance standards and ESD protection levels specified in the product data sheet before finalizing procurement.

Selection Notes

Select this component when designing interfaces between mixed-voltage domains requiring high noise immunity and low ground bounce. The integrated termination resistors make it suitable for high-speed applications without external components. Ensure the design accommodates the dual-supply capability if translating between different voltage nodes.

Part Context

This part belongs to the 74LVC/LVCH family of logic ICs manufactured by Nexperia. It is specifically designed as a 16-bit transceiver with direction control pins. The ADGG suffix indicates the TSSOP48 plastic thin shrink small outline package with a body width of 6.1 mm.

Replacement Considerations

The 74LVC162245ADGG is functionally equivalent regarding pinout and electrical characteristics but lacks the bus hold feature found in the LVCH variant.
