SN74LVC162244ADGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC162244ADGGR is a 16-bit buffer and driver featuring 3-state outputs, designed for operation within a supply voltage range of 1.65 V to 3.6 V. It provides symmetrical active-low output-enable inputs and accepts input voltages up to 5.5 V, facilitating mixed-mode signal operation in systems with 3.3-V or 5-V logic levels. The device includes equivalent 26-Ω series resistors on the output ports to minimize overshoot and undershoot without requiring external components. It supports partial power-down applications through Ioff circuitry, which prevents damaging backflow currents when the device is powered down.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against the orderable addendum, as the DGGR suffix denotes the TSSOP (DGG) package. Confirm RoHS compliance and lead finish specifications, typically NIPDAU, prior to procurement. Ensure the selected part status is listed as Active Production. Cross-reference the moisture sensitivity level and peak reflow temperature ratings with your assembly process requirements to guarantee compatibility.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit unidirectional buffer with high drive capability and 5.5-V tolerant inputs is required. It is suitable for translating signals between different voltage domains, such as 3.3-V and 5-V systems. Consider the maximum propagation delay and output current limits relative to your load conditions. Ensure unused inputs are tied to VCC or GND to prevent floating states and excessive power consumption during operation.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to Texas Instruments' Widebus Family, designed to improve performance and density in bus-oriented receivers and transmitters. It can be configured as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. The SN74LVC162244A series is optimized for memory address drivers and clock drivers, offering balanced output drive and fast edge rates suitable for high-speed digital applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVC162244ADGVR is a functional substitute with an identical electrical specification but utilizes the TVSOP (DGV) package instead of the TSSOP (DGG) package.
