SN74ABT162244DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT162244DGGR is a 16-bit buffer and line driver from the Widebus family, designed for high-performance memory address drivers, clock drivers, and bus-oriented receivers. It operates at a supply voltage of 4.5 V to 5.5 V with symmetrical active-low output-enable inputs. The device features noninverting outputs capable of sourcing or sinking up to 12 mA, incorporating equivalent 25-Ω series resistors to minimize signal overshoot and undershoot. It supports hot-insertion via Ioff circuitry and power-up 3-state functionality. Packaged in a 48-pin TSSOP (DGG) format, it ensures distributed VCC and GND pins to reduce high-speed switching noise.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGGR' corresponds to the TSSOP-48 package and tape-and-reel packaging configuration. Confirm that the component meets the required RoHS compliance standards and lead finish specifications (NIPDAU). Ensure the operating temperature range aligns with the -40°C to +85°C catalog rating for this specific part number variant.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit buffering with integrated termination resistors to simplify PCB design. It is suitable for applications needing hot-insertion support and robust latch-up protection exceeding 500 mA per JESD-17. Consider its flow-through pinout if optimizing trace routing density is a priority over other logic families.
