74LVC162244ADGG,11

Overview

The Nexperia 74LVC162244ADGG,11 is a 16-bit buffer and line driver featuring integrated 30 Ω series termination resistors and 5 V tolerant inputs and outputs. It provides three-state outputs controlled by four independent output enable signals (1OE, 2OE, 3OE, 4OE). The device operates on a supply voltage range of 1.2 V to 3.6 V and supports an input voltage up to 5.5 V. It includes Schmitt-trigger action for noise immunity and IOFF circuitry for partial power-down protection. The component is housed in a 48-lead TSSOP package (SOT362-1) and functions across an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Integrated 30 Ω series termination resistors for signal integrity
• IOFF circuitry prevents backflow current during partial power-down
• Schmitt-trigger inputs provide tolerance for slow rise and fall times
• Bus hold feature on data inputs eliminates the need for external pull-up resistors

Applications

• Mixed 3.3 V and 5 V logic environments
• Multibyte flow-through standard pin-out architectures
• Partial power-down applications requiring backflow prevention

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the application environment remains within the specified absolute maximum ratings to prevent permanent damage. Ensure design safeguards are implemented to minimize risks associated with the product's use in customer applications.

Selection Notes

Select this component when designing systems requiring 16-bit buffering with built-in termination resistors. It is suitable for interfaces between devices operating at different voltage levels, specifically those involving 3.3 V and 5 V domains. The inclusion of bus hold features simplifies board layout by removing the need for external pull-up components on unused inputs.

Part Context

This part belongs to the 74LVC162244A family of 16-bit buffers and line drivers manufactured by Nexperia. It is designed for high-speed digital applications where signal integrity and voltage translation are critical. The device complements other logic families by providing robust interface capabilities between varying voltage standards.

Replacement Considerations

Direct substitutes include the 74LVCH162244ADGG,11 variant, which shares identical pinout and functional characteristics but may differ in specific electrical parameters such as propagation delay or drive strength. Verify compatibility before substitution.
